Safety Information The Welch Allyn Atlas Monitor is intended for use in a hospital or clinical environment. It should not be used at home or in emergency transport vehicles. Monitor users should be skilled at the level of a technician, nurse, doctor or medical specialist. The function of the Welch Allyn Atlas Monitor is to register ECG, CO2 concentration, Heart Rate, Noninvasive Blood Pressure (Systolic, Diastolic, and Mean Arterial Pressure), Pulse Oximetry, Respiration Rate and Temperature for adult and pediatric patients (over the age of 3 years), in all hospital or clinic facilities. To ensure patient electrical isolation, the Atlas Monitor should only be connected to other equipment that provides patient electrical isolation. When connecting the Welch Allyn Atlas Monitor to any instrument, verify proper operation before clinical use. Accessory equipment connected to the monitor’s serial data interface must be certified according to IEC Standard 950 for data-processing equipment or IEC Standard 60601-1 for electromedical equipment. All combinations of equipment must be in compliance with IEC Standard 60601-1-1 systems requirements. Anyone who connects additional equipment to the signal input / output port is configuring a medical system and is therefore responsible that the system comply with the requirements of IEC Standard 60601-1-1. If in doubt, consult the Welch Allyn Technical Service Department. The Welch Allyn Atlas Monitor and its accessories should be tested by qualified service personnel at regular intervals to verify proper operation, according to the procedures of the user’s institution. A Service Manual is available from the manufacturer. Other important safety information is located throughout this manual where appropriate.

The Welch Allyn Atlas Monitor is designed for use by medical clinicians. Although this manual may illustrate medical monitoring techniques, this system should only be used by a trained clinician who knows how to take and interpret a patient’s vital signs. Do not operate this product in the presence of flammable anesthetics. Explosion may result. WARNING – PACEMAKER PATIENTS. Rate meters may continue to count the pacemaker rate during occurrences of cardiac arrest or some arrhythmias. Do not rely entirely upon rate meter alarms. Keep pacemaker patients under close surveillance. See this manual for disclosure of the pacemaker pulse rejection capability of this instrument. This device must be used in conjunction with clinical signs and symptoms. This device is only intended to be an adjunct in patient assessment. Certain arrhythmias or pacemaker signals could adversely affect heart rate indications or alarms. During defibrillation, keep the discharge paddles away from ECG and other electrodes, as well as other conductive components in contact with the patient. Avoid contact with any accessories connected to the Welch Allyn Atlas Monitor’s panel. If pulse oximetry measurements are suspect, verify the reading using another clinically accepted measurement method. Prolonged use or the patient’s condition may require changing the SpO2 sensor site periodically. Change sensor site and check skin integrity, circulatory status, and correct alignment at least every 4 hours. When monitoring blood pressure over an extended period of time, or at frequent intervals, it is recommended to check the cuff site and cuffed extremity regularly for possible ischemia, purpura and/or neuropathy. Thoracic impedance respiration measurement may interfere with some pacemakers. Refer to the pacemaker’s manual. To ensure patient safety, the conductive parts of the ECG electrodes (including associated connectors) and other patient-applied parts, should not contact other conductive parts, including earth ground, at any time. The safety and effectiveness of this product in the detection of apnea, particularly for infants and neonates, has not been established. This equipment must not be connected to any other equipment that is not compliant with EN60601-1, or a possibility exists that combined leakage currents could exceed safe limits. Do not fit the Blood Pressure or ETCO2 systems with Luer Lock adapters. There is a risk of a user mis-connection with an IV line introducing air bubbles into a patient’s blood. WARNING: Use of accessories, transducers, and cables other than those specified may result in degraded electromagnetic compatibility performance of this device. Do not operate this product with MRI (Magnetic Resonance Imaging) equipment. It is the operator’s responsibility to set alarm limits as appropriate for each individual patient. Any Atlas Monitor which has been dropped or damaged should be checked by qualified service personnel to insure proper operation prior to use. There are no user serviceable parts inside the Atlas Monitor other than paper replacement and battery replacement. Blood pressure measurements may not be accurate for patients experiencing moderate to severe arrhythmias. This Atlas Monitor should not be used on patients who are linked to heart / lung machines. If the integrity of the external protective conductor in the installation or its arrangements is in doubt, equipment shall be operated from its internal power source (models 622xx and 623xx).

If an electrosurgical unit is used, place the ECG cable and wires as far as possible from the site of the surgery and from the electrosurgical cables. This will minimize interference and the risk of burns to the patient. Ensure that the electrosurgical return cable (neutral) is well attached and making good contact with the patient. End tidal carbon dioxide (ETCO2) and breath rate measurement and alarm capability are active ONLY when the second trace option is set to CO2. Should the operator change from viewing the ETCO2 and breath rate waveforms and data to another second trace selection (SpO2, Respiration or ECG) the CO2 and breath rate monitoring and alarm capability will be disabled. This occurs even if the watertrap and cannula are still inserted into the Monitor. Impedance Respiration rate measurement and alarm capability are active ONLY when the second trace option is set to Respiration. Should the operator change from viewing the Respiration waveforms and breath rate to another selection (SpO2, CO2 or ECG) the Respiration rate monitoring and alarm capability will be disabled. This occurs even if the ECG cable is still inserted into the Monitor. If you are using battery power, the AC indicator (AC~) on the front panel will NOT be lit. When the Atlas monitor is running on battery power, it will warn you when there is less than 10, less than 5, and less than 1 minute of life remaining in the battery. See section 3.4 for battery alarm information. When using the motion tolerant pulse oximetry channel, a very sudden and substantial change in pulse rate can result in erroneous pulse rate readings. Be sure to validate the patient data and patient condition before intervention or change in patient care. When using the 6200-12 ECG Wrist-Klip, although a normal Lead I QRS waveform is produced on the monitor, this waveform should not be used for serious clinical interpretation because the electrodes are not properly triangulated around the patient’s heart. The 6200-12 ECG Wrist-Klip cannot be adjusted in size. Proper orientation of the clip with the monitor depends on adjusting the position of the clip until a snug fit is found. The preferred position of the clip is the patient’s wrist but it can be moved up the patient’s arm toward the torso. You may find that the clip will not work with patients that have small wrists and arms. Caution must be exercised when placing the clip so that circulation is not impeded along the patient’s wrist and arm. If a snug fit cannot be found on the patient, other means of monitoring must be used.

Cautions •

• • •

• •

When transporting or storing the Atlas monitor at temperatures between 40°C (104°F) and 50°C (122°F), the following procedure must be performed. The monitor must be returned to the normal operating temperature range of 10°C (50°F) - 40°C (104°F) for a period of at least two hours. If patient monitoring is performed before two hours has elapsed, the displayed and printed ETCO2 values may be higher than the patient's actual values. Place the Welch Allyn Atlas Monitor and accessories in locations where they cannot harm the patient if they fall off a shelf or mount. Never place fluids on top of this monitor. In case of fluid spilling on the monitor, disconnect power cord, wipe clean immediately and have the monitor serviced to ensure that no hazard exists. This Welch Allyn Atlas Monitor should not be stacked directly on top of other equipment, and other equipment should not be stacked on top of this Welch Allyn Atlas Monitor. If stacking is necessary, observe the Welch Allyn Atlas Monitor to verify normal operation in the stacked configuration in which it will be used. Unplug the external power cord from the monitor before cleaning or disinfecting the monitor. Do not autoclave, subject to ethylene oxide sterilization, or immerse the Welch Allyn Atlas Monitor in liquid. Sterilize accessories only according to the manufacturer’s instructions.

• • • • • • • •

Make frequent electrical and visual checks on cables and electrode wires. Ensure the AC rating for the device is correct for the AC voltage at your installation site before using the monitor. The AC rating is shown on the back of the instrument. If the rating is not correct, do not use the monitor, and contact the Welch Allyn Technical Service Department for help. Line isolation monitor transients may resemble actual cardiac waveforms and thus inhibit heart rate alarms. Use care in placement of ECG electrodes and routing of cables to avoid interference and noise. Electrode polarization: the type of electrode used can affect the recovery time from overload, especially defibrillation. Electrodes of dissimilar metals should not be used. If the accuracy of any measurement is in question, check the patient’s vital sign(s) by an alternate method and then check the Atlas Monitor for proper functioning. Extremity and cuff motion should be minimized during blood pressure determinations. The pulse oximeter is calibrated to determine the percentage of arterial oxygen saturation of functional hemoglobin. Significant levels of dysfunctional hemoglobins such as carboxyhemoglobin or methemoglobin may affect the accuracy of the measurement. Grounding reliability can only be achieved when equipment is connected to an equivalent receptacle marked “Hospital Only” or “Hospital Grade”.

Notes • • • • • • •

If the Atlas monitor is stored or transported at temperatures outside of the published storage temperature range of -20°C (-4°F) - 50°C (122°F) the Atlas monitor will not perform to the published accuracy standards. Sidestream waste material and the CO2 watertrap should be treated as biohazard material. Blood pressure measurements determined with this device are equivalent to those obtained by a trained observer using the cuff/stethoscope auscultation method, within the limits prescribed by the American National Standard, Electronic or automated sphygmomanometers (SP 10). Blood Pressure measurements can be affected by the position of the patient, by the patient’s physiological condition, and other factors. The Blood Pressure system and Temperature system may not meet specifications if operated or stored at conditions outside the stated ranges, or subjected to excessive shock or dropping. The Blood Pressure system is compliant with requirements of EN 1060-3:1995 Specification for Noninvasive Sphygmomanometers. The Atlas Monitor is designed with protective circuitry and current isolation that eliminates any risk to the patient from possible software errors.

1 How This Manual Works This manual is arranged so that everything about one topic is found in a single section. The statement immediately below the chapter title (like this one) appears in italics and presents the important points of the topic. Most topics include an illustration or a table. The chapters are numbered so that logically connected topics begin with the same number-- for example 2.1 and 2.2. The Welch Allyn Atlas Monitor and this manual are designed for ease of use. Everything you need to know about a specific operation of the monitor is available in one place. This means you can see all the required information at a glance.

will give you enough information. Section Numbers - The double numbered pages indicate the relationship between the main subject and closely related topics. The sections are organized so that what you want to know first is put first. Like most medical professionals who use the Atlas Monitor, you are probably very adept at taking blood pressure and connecting ECG leads to patients, so the section on how the Atlas Monitor is used for monitoring patients and what you need to know to operate the monitor comes first. We put the information on connecting blood pressure cuffs and ECG leads in a later section.

Redundancy - There is some redundancy in this manual; some step-by-step procedures are repeated in many places wherever they are pertinent. We did this so you would not have to search through other pages to find what you need to know “right now.” For instance, setting an alarm limit is fully explained in the section on blood pressure, again in the section on SpO2, and in several other places.

This manual is not meant for reading straight through, like a book, although you can read it that way. If you read it like this, the built-in redundancy may become a little tedious. When you read a paragraph or a step-by-step procedure with which you are already familiar, just skip it. It is there for the person who is doing the activity for the first time.

Paragraphs - The statement in italics immediately below the chapter heading describes what the section is about. Sometimes just reading this and looking at the illustrations

1.1 A Quick Tour of the Welch Allyn Atlas Monitor When you turn on the power, the monitor starts with preset or default alarm levels. Waveforms are displayed on the screen. Readings are displayed on the screen and on LEDs. You can perform the most common operations - set and silence alarms, display trend data, print waveforms and trend data - from the front panel without using a menu. This section gives only a brief overview of the monitor; later sections present all the details. A lit AC~ indicator, located below the screen, means the unit is being powered by the wall outlet, and that the battery is being charged (models 622xx and 623xx).

Which model do you have? The Welch Allyn Atlas Monitor is a single, portable unit providing all the measurement capability normally needed to monitor patients under anesthesia, patients recovering from surgery, and patients who require bedside monitoring. The model number is encoded into the first three digits of the serial number on the back of the unit. There are three models:

SpO2, SpO2 waveform Pulse Rate NIBP: Systolic, Diastolic, MAP ECG waveform, heart rate Printer (optional) All features of model 621xx, plus: Impedance Respiration Patient Temperature Battery Operation PC Communication Remote Nurse Call Printer (optional) All features of model 622xx, plus: End Tidal CO2 and Breath Rate from ETCO2 Printer (standard)

622NO 622NP

623NP

NOTE: Use the battery as a backup for low power conditions or short-term transports. Silencing Alarms - You can silence any alarm for 90 seconds by pressing the large blue Silence button on the right-hand edge of the instrument. Silenced alarms continue to flash, as long as the measurement is outside the alarm limits. When alarms are silenced, they will not trigger a Print On Alarm. When the silence period is over, an alarm that is still active will trigger a Print On Alarm if the Print On Alarm configuration is set to Yes. You can suspend an individual alarm by pressing its ALARMS Off button. There are four ALARMS Off buttons, each controlling a different group of measurements. The audible alarm is suspended as long as the red LED in the button is lit. When an alarm is suspended, the audible alarm will not sound, but readings will still flash when the measurement is outside the limits. When an alarm is suspended, it will not trigger a Print On Alarm. When the alarm is unsuspended, an alarm that is still active will trigger a Print On Alarm if the Print On Alarm configuration is set to Yes.

Power on - The Power On/Standby button is in the lower right corner. When you first turn on the monitor: • all alarms are enabled, but no alarm will sound until after a valid measurement value is received. • all alarm limits are set at their default values. • all the trend data (history) is cleared.

Note: Individual alarms can be suspended for only 3 minutes when the language setting is configured to “Francais”. If the language is set to any other language, pressing the individual ALARMS Off buttons will suspend the alarm until you remove the suspension.

2

Trend Data - Trend data is captured every time blood pressure is measured, whether this event is automatic or manual. Trend data is also automatically captured every 15 minutes if blood pressure intervals are longer, or blood pressure is not used. Push the Trend button to see the trend data. Scroll through the trend data with either Set button. Push Trend again to return to the waveform display. The monitor will hold up to 144 lines of trend data, which is 36 hours if data is captured every 15 minutes. Printing - A printer option is available with both models 621xx and 622xx, and is a standard model 623xx feature. Push the Print button to print what is on the screen. If the waveforms are displayed on the screen, the Print button prints 15 seconds of waveforms plus all the current measurements. The printout captures data from 9 seconds before the Print button was pressed until 6 seconds after. Note: If any measurements exceed the alarm limits, they will be marked with asterisks on the printout. If trend data is displayed on the screen, Print prints all the trend data. If the Print On Alarm configuration is set to Yes, and a Patient Alarm or Measurement Invalid Alarm occurs, Atlas will print the current measurements and the currently configured waveforms automatically. If your model of the Atlas Monitor does not have the optional printer, the Print button is labeled Freeze, and it freezes, or halts, the waveform display for 10 seconds to permit studying of the waveform.

3

2 Monitoring the Patient The patient’s vital measurements are displayed as numeric readings and as waveforms. You can set the measurement limit alarm levels, silence the alarms for a short period, and suspend individual alarms. You can print waveforms and current measurements, or print all the stored trend data. all alarms for 60, 90 or 120 seconds. This silence period can be set to one of these three choices in Advanced Configuration. During the silence period, there will be no audible alarms, even for measurements that go outside the limit range for the first time. However, any measurement that is outside the limits you set will flash. When alarms are silenced, they will not trigger a Print On Alarm. When the silence period is over, an alarm that is still active will trigger a Print On Alarm if the Print On Alarm configuration is set to Yes.

The front panel has two sides: The left side displays waveforms, numeric readings, and trend data on a CRT screen.

The right side has measurements displayed in green and red LEDs.

Each side responds to the adjacent Select and Set buttons used for setting alarm limits. Each side also has ALARMS Off buttons, which are used to suspend (turn off) individual alarms.

Trend data - Press the Trend button to see the trend data. The waveform display is replaced by the first screen of trend data, starting with the most recent measurements at the top. View the rest of the trend data by pressing the Set button up or down.

Note: Individual alarms can be suspended for only 3 minutes when the language setting is configured to “Francais”. If the language is set to any other language, pressing the individual ALARMS Off buttons will suspend the alarm until you remove the suspension. Note: The temperature measurement does not have an alarm.

The trend memory can hold up to 144 lines of measurements, which is 36 hours of data if taken at 15-minute intervals.

Setting alarm limits - Press the Select button to choose which alarm limit you want to set. Each time you press the Select button, it cycles to the next alarm, shown by small HI and LO indicators, and the measurement display flashes the current alarm setting. The Set button changes this alarm limit. Press the top or bottom of the button to change the limit up or down.

Printing - The Print button prints what you see on the screen - the waveforms (including all current measurements) or the screen with trend data. When you push the button, waveforms are printed starting from 9 seconds before you pushed the Print button until 6 seconds after you pushed the button for a total printout of 15 seconds. The other information on the printout is captured at the time that the Print button is pressed. If the Print On Alarm configuration is set to Yes and a Patient Alarm or Measurement Invalid Alarm occurs, Atlas will print the current measurements and the currently configured waveforms automatically.

Note: the flashing alarm-setting mode only lasts 10 seconds before reverting back to the normal measurement mode. If you take too long to set a limit, you’ll need to press the Select button and start over again. Press the Select button to go to the next measurement alarm. Press it several times to cycle out of all the alarm settings and go back to the normal measurement mode.

Freeze – If your monitor does not have a printer, the button is labeled Freeze. Pressing Freeze stops the waveform display for 10 seconds, and then the readout resumes.

2.1 Monitoring Blood Pressure Blood pressure can be measured at timed intervals which you set, or you can start the blood pressure measuring cycle manually. Systolic and Diastolic readings are shown on the LEDs at the upper right of the monitor. You can set the high and low alarm limits for both the systolic and diastolic measurements. Blood pressure cycles - You can measure NIBP at timed intervals or manually. To set a timed interval, press the Auto button to cycle through the available intervals: X, 1, 3, 5, 10, 15, 30, or 60 minutes. Wait until the number for the selected interval stops flashing; the measurement will automatically begin 20 seconds later.

Alarm configuration is set to Yes, a blood pressure alarm will trigger an automatic print. You can silence the blood pressure alarm, and all alarms, by pressing the large blue Silence button at the right side of the instrument. This will silence all alarms for 60, 90, or 120 seconds, depending on the setting selected in Advanced Configuration. However, any measurement still outside the set limits will flash. When alarms are silenced, they do not trigger a Print On Alarm.

Note: The interval is timed from the start of one BP cycle to the start of the next cycle. Pressing the button one more time after the 60 is lit will return the Auto timing to the Off mode (indicated by an “X”). In this mode, automatic measurement at timed intervals will not occur. Initially, both blood pressure displays will be blank.

To suspend the blood pressure alarms, press the BP ALARMS Off button so the red LED in the button lights. A suspended alarm will still flash if it goes outside the range of the limits, but it will not sound the audible alarm. When an alarm is suspended, it will not trigger a Print On Alarm.

Stopping a blood pressure cycle - The BP Start/Cancel button does one of two things: • If a blood pressure measurement is not in progress, pressing BP Start/Cancel will start a blood pressure measurement cycle, whether the Auto timer is set to a specific interval or is off. • If a blood pressure measurement is in progress, pressing BP Start/Cancel will deflate the cuff immediately and cancel the measurement. If the Auto button is in one of the timed modes, the cuff will inflate again after the selected number of minutes.

Note: The blood pressure alarm can be suspended for only 3 minutes when the language setting is configured to “Francais”. If the language is set to any other language, pressing the BP ALARMS Off button will suspend the alarm until you remove the suspension. Trend data – Trend data is captured at each blood pressure cycle, whether it is started automatically or manually. If the Auto timing of NIBP is off (X), or greater than 15, then trend data is captured every 15 minutes.

Note: Canceling a blood pressure cycle does not end automatic BP timing. If the Auto is set to any number, the next blood pressure cycle will start again after that number of minutes has elapsed.

Initial pressure – The initial cuff pressure can be set in the Advanced Configuration. The Atlas Monitor will pump up to the selected initial cuff pressure. If this pressure is too low to measure the systolic pulse, the system will repeatedly increase pressure by 40 mmHg and measure again.

Alarms - When any of the blood pressure limits are exceeded, an audible alarm sounds and the affected measurement flashes. If the Print On

The instrument is now in its normal measurement mode. (If you do not press any button for 10 seconds, the instrument will automatically revert to its normal measurement mode).

Setting alarm limits - To set the Systolic and Diastolic alarm limits, use the Select and Set buttons on the right side of the monitor to follow these steps: • Press the Select button to cycle through SpO2 LO, then Systolic HI and LO, and Diastolic HI and LO. • Each push of Select moves you to the next limit. Stop at the limit you want to set. The measurement and the HI or LO LED will flash, indicating which limit is being changed. • Press the Set button up or down to raise or lower the alarm limit. (When you come to the end of the range, the numbers will stop changing). • Press the Select button again to go to the

Note: If the language setting is configured to Chinese and the alternate BP field to kPa, the blood pressure will be displayed in kPa on the screen, but the Systolic and Diastolic readings on the right side of the monitor will be displayed in mmHg. When setting the alarm limits, the HI and LO alarm limits will be displayed in mmHg on the right side of the monitor and in kPa on the screen.

2.1.1 MAP (Mean Arterial Pressure) Mean Arterial Pressure is calculated from the systolic and diastolic measurements. MAP may be optionally displayed by selecting it on the Advanced Configuration menu. MAP is displayed in the upper left corner of the screen. MAP - (Mean Arterial Pressure) display can be turned on and off by using the Advanced Configuration menu. When MAP is shown, you will see it in the upper left corner of the screen, above the ECG waveform.

suspended, it will not trigger a Print On Alarm. Note: The BP alarm can be suspended for only 3 minutes when the language setting is configured to “Francais”. If the language is set to any other language, pressing the BP ALARMS Off button will suspend the alarm until you remove the suspension.

To display (or turn off) MAP, enter the Advanced Configuration menu: • Press the Date/Time button. • Press the Trend button. • Use the left Select button to highlight “MAP.” • Press the left Set to choose “Yes” or “No.” • Press the Trend button again to exit Advanced Configuration.

Note: MAP is calculated mathematically from the Systolic and Diastolic pressures; it is not measured directly. Setting alarm limits – If MAP is displayed, you can set the alarm limits, using the Select and Set buttons on the left side of the monitor to follow these steps: • Press the left Select button to cycle through MAP HI and LO, Heart Rate HI and LO, Respiration HI and LO (models 622xx or 623xx) , then (model 623xx) CO2 HI and LO. • Each push of Select moves you to the next limit. Stop at the limit you want to set. The measurement and HI or LO will flash, indicating which limit is being changed. • Press the Set button up or down to raise or lower the alarm limit. (When you come to the end of the range, the numbers will stop changing). • Press the Select button again to go to the next limit, or press it several times until none of the measurements flash and no HI or LO indicators are lit. The instrument is now in its normal measurement mode. (If you do not press any button for 10 seconds, the instrument will automatically revert to its normal measurement mode).

If MAP is displayed on the screen, it will also appear in the trend data and in the current readings of a waveform printout. Alarms - When either of the MAP limits are exceeded, an audible alarm sounds and the affected measurement flashes. If the Print On Alarm configuration is set to Yes, a MAP alarm will trigger an automatic print. You can silence the MAP alarm, and all alarms, by pressing the large blue Silence button at the right side of the instrument. This will silence all alarms for 60, 90, or 120 seconds, depending on the setting selected in Advanced Configuration. However, any measurement still outside the set limits will flash. When alarms are silenced, they do not trigger a Print On Alarm. To suspend the MAP alarm, press the BP ALARMS Off button so the red LED in the button lights. A suspended alarm will still flash if it goes outside the range of the limits, but it will not sound the audible alarm. When an alarm is
