Welch Allyn Vital Signs Monitor
Monitor Service Manual 95P445E Rev. C
General Information
Section 1
Introduction The Welch Allyn Vital Signs Monitor, also marketed as QuickSigns, is designed to noninvasively and automatically measure systolic and diastolic pressure, pulse rate, temperature and oxygen saturation (SpO2) for adult and pediatric patients. THE WELCH ALLYN VITAL SIGNS MONITOR IS NOT TO BE USED ON NEONATAL PATIENTS. All blood pressure, pulse, temperature and SpO2 values can be viewed on a large, easy-toread display, and may be printed via the integrated printer as desired. The rechargeable lead acid battery and variety of mounting accessories make the Welch Allyn Vital Signs Monitor convenient for many locations. The operator may choose any combination of simultaneous measurement modalities. This flexibility, combined with features such as programmable alarms and automatic BP cycles, makes the Welch Allyn Vital Signs Monitor ideal for a wide variety of patient monitoring needs. Refer to the Welch Allyn Vital Signs Monitor Operator’s Manual for complete information on Indications For Use, Special Features, Supplies and Accessories.
Basic System Operation Blood Pressure Operating Modes When a blood pressure measurement cycle is initiated, the cuff will automatically inflate to the default pressure level. The cuff will immediately begin to deflate in a stepped fashion and will determine systolic pressure and diastolic pressure from the pulses sensed by the cuff at various pressure levels. This is the oscillometric method of non-invasive blood pressure monitoring. Blood pressure measurements may be initiated manually, or automatically at time intervals determined by the user. At the completion of a measurement cycle the systolic and diastolic pressures are displayed. If the Monitor is in Automatic Mode, the measured values are kept on display until the next BP measurement is initiated. When not in Automatic Mode, the measured values are displayed for two minutes, after which time the display screen is blanked. The most recent BP measurement may be recalled by pressing the REVIEW button. When in Automatic Mode, if the unit is unable to determine the systolic or diastolic value, the measurement will be automatically repeated once. Blood Pressure Manual Mode In the Manual Mode, a single blood pressure determination is made only when the START button is pushed. The manual mode is the default mode of operation for blood pressure determinations. A measurement cycle may be cancelled at any time by pressing the CANCEL button. This action immediately initiates a rapid cuff deflation. Service Manual 95P445E Rev. C
Welch Allyn Vital Signs Monitor 5
Section 1
General Information
The blood pressure measurement data will appear on the display immediately following the measurement. The display will blank after two minutes. If the display is blank, pressing the REVIEW button on the front panel will recall the measurement. Up to 99 prior measurements are available for review or printing. In Blood Pressure Manual Mode, the following alarm limits may be activated; SYSTOLIC HIGH LIMIT, SYSTOLIC LOW LIMIT, DIASTOLIC HIGH LIMIT, DIASTOLIC LOW LIMIT, PULSE RATE HIGH LIMIT and PULSE RATE LOW LIMIT. Blood pressure determinations, which activate alarms, are indicated by flashing displays and a repetitive audible tone. If an alarm limit is violated, subsequent blood pressure determinations may be made only after the alarm condition is reset by pressing any button on the Monitor's display. Blood Pressure Automatic Mode The Automatic Blood Pressure Mode is entered by pressing the AUTO button. Pressing the AUTO button displays a choice of 11 cycle interval times as follows: "St" (STAT mode), 1 minute, 3 minutes, 4 minutes, 5 minutes, 10 minutes, 15 minutes, 30 minutes, 45 minutes, 60 minutes and 90 minutes. These choices represent the time interval from the beginning of one cycle to the beginning of the next automatic cycle. STAT mode allows the monitor to take continuous blood pressure measurements for 15 minutes. In addition, the operator may choose to disable the Auto Mode by choosing “--” (two dashes). Note: In the 1-minute automatic cycle mode, the Welch Allyn Vital Signs Monitor will automatically take blood pressure measurements in 1-minute intervals for up to 15 minutes. A measurement cycle may be cancelled at any time by pressing the CANCEL button. This action immediately initiates a rapid cuff deflation. The blood pressure measurement data will appear on the display immediately following the measurement and will remain displayed until the next measurement cycle is initiated. In Blood Pressure Auto Mode, the following alarm limits may be activated; SYSTOLIC HIGH LIMIT, SYSTOLIC LOW LIMIT, DIASTOLIC HIGH LIMIT, DIASTOLIC LOW LIMIT, PULSE RATE HIGH LIMIT and PULSE RATE LOW LIMIT. Blood pressure determinations, which activate alarms, are indicated by flashing displays and a repetitive audible tone. Any alarm limit violation must be reset to continue automatically timed blood pressure determinations. The alarm may be reset by pressing any button on the Monitor's display. Temperature Operating Modes Thermometry measurements are made with the integrated Welch Allyn SureTempTM thermometer. Oral and rectal probes utilize single-use disposable probe covers which limit cross-contamination. Oral, axillary or rectal temperatures are taken using Normal or Monitor operating modes. Axillary temperatures are taken using the oral probe.

Monitor Service Manual 95P445E Rev. C
General Information
Section 1
In Normal mode the thermometer's microprocessor "predicts" body temperature in about 4 seconds for oral temperatures, about 10 seconds for axillary temperatures and in about 15 seconds for rectal temperatures. The Monitor mode displays the patient's actual temperature after 3 minutes for oral/rectal mode and 5 minutes for axillary mode, and will continue to display an updated temperature as long as the probe remains in place. Note: Normal mode axillary temperatures (10 seconds) are accurate only for children under the age of four. Note: The Welch Allyn Vital Signs Monitor is not intended to be used on Neonatal patients. Temperature readings may be displayed in Fahrenheit or Celsius scales. Temperature Normal Mode In Normal mode, the device will measure temperature at discrete intervals and then calculate the rate of change according to a proven algorithm. This allows the thermometer to predict the end point that the thermistor would reach if it were left in the mouth until it reached mouth temperature. This predictive feature allows the thermometer to arrive at an accurate oral temperature reading in approximately 4 seconds. Normal mode is the default operating mode for temperature determinations. Operator selectable patient alarm limits are not available in temperature Normal mode. However, temperatures which are outside of the operating range of the device will be noted on the temperature display. Temperature Monitor Mode Continuous Monitor mode operation is normally used for longer term monitoring and when difficult situations prevent accurate temperatures from being taken in the Normal mode. The probe must be in contact with tissue for at least three (3) minutes for accurate oral/rectal temperature measurement and five (5) minutes for accurate axillary temperature measurement. Monitor mode temperatures may not be identical to predicted 'Normal' temperatures because of ambient temperature influence and other factors. The trend in temperature is the important standard to be observed when in the Monitor mode. Operator selectable patient alarm limits are not available in temperature Monitor mode. However, temperatures which are outside of the normal operating range of the device will be noted on the temperature display. SpO2 Operating Mode The Welch Allyn Vital Signs Monitor incorporates the Nellcor Puritan BennettTM pulse oximetry module which determines arterial oxyhemoglobin saturation (SpO2%) by measuring the absorption of red and infrared light passed through the tissues. Changes in absorption caused by pulsation of blood in the vascular bed are used to determine arterial saturation and pulse rate.
Service Manual 95P445E Rev. C
Welch Allyn Vital Signs Monitor 7
Section 1
General Information
Oxygen saturation percent is calculated with each pulse detected, and thus the monitor display is continually updated. The pulse signal bar graph is an indicator of the strength and quality of the detected pulses. When SpO2 is measured, the patient's pulse rate is also measured and displayed. A pulse rate measurement from the SpO2 determination overrides a pulse rate measurement derived from a blood pressure measurement. When measuring SpO2 the user may enable the SpO2 Pulse Tone feature. A short audible tone is emitted with every patient heartbeat. The frequency of the tone is based on the patient’s SpO2 level. The lower the frequency of the tone, the lower the patients SpO2 level. In SpO2 monitoring mode, operator selectable alarm limits for low SpO2% may be activated. A condition which violates the SpO2 low limit alarm is indicated by a flashing display and repetitive audible tone. Should a patient alarm condition for SpO2 or pulse rate occur, the Monitor will indicate an alarm condition (flashing & beeping) while continuing to monitor and display the patient's current SpO2%. The alarm will automatically reset when the patient's condition returns to within the preset alarm parameters. Should a patient alarm condition for SpO2 or pulse rate occur, the operator may invoke "Silence Mode" by pressing the SILENCE button. This will silence the audible tone (display will continue to flash), while the practitioner attends to the patient and the monitor. Silence mode resets automatically after 30 seconds, or when the patient's condition returns to within the preset alarm parameters. Removal of the SpO2 sensor from the patient will initiate an alarm, unless the SpO2 and pulse rate alarms are turned off. To reset the sensor alarm, press any button on the Monitor's display. SpO2 is generally measured via pulses detected using a finger sensor. However, for certain situations SpO2 may be measured at alternate sites including the earlobe, forehead and toes. Special sensors must be employed in these situations. SpO2 Monitor Mode The SpO2 monitor performs most accurately with the fingerclip sensor, which may be used on all fingers except the thumb. The finger clip sensor is recommended for spot checks or short term continuous monitoring. The device determines arterial oxyhemoglobin saturation (SpO2%) by measuring the absorption of red and infrared light passed through the tissue. Oxygen saturation and pulse rate are displayed on the LED digital display. On each detected pulse, the pulse signal bar graph flashes. The intensity of this signal is a simple visual indicator of waveform signal strength, and can identify situations where the pulsatile nature of the tissue may not be adequate for an accurate SpO2 reading. The update interval of the bar graph should correspond to the patient's pulse rate. This is an indication of the quality of the SpO2 signal. 8
Welch Allyn Vital Signs Monitor
Monitor Service Manual 95P445E Rev. C
General Information
Section 1
All Welch Allyn Vital Signs Monitors with pulse oximetry capability are equipped with a pulse tone. This audible tone beeps in synchronization with each beat of the patient’s heart. In addition, the frequency of the tone will vary based on the patient’s oxygen saturation value. The higher the tone’s frequency, the higher the patient’s oxygen saturation value. The user may change the pulse tone volume, or turn this feature off as necessary. Pulse Rate Feature The Welch Allyn Vital Signs Monitor is capable of determining pulse rate as an adjunct to the blood pressure measurement and the SpO2 measurement. The pulse rate, in beats per minute, will be determined primarily from the SpO2 measurement methodology. In the case where SpO2 is not available, or is disabled, the pulse rate display will be driven by data from the blood pressure measurement method. There are two operator selectable alarm limits for the pulse rate. They are PULSE RATE HIGH LIMIT and PULSE RATE LOW LIMIT. Pulse rates which activate alarm limits are indicated by a flashing display and a repetitive audible tone. Should a pulse rate alarm occur when the pulse rate measurement is derived from the blood pressure measurement, no subsequent blood pressure or pulse rate measurements may be made until the alarm is reset. The alarm may be reset by pressing any button on the Monitor's display. Should a pulse rate alarm occur when the pulse rate measurement is derived from the SpO2 measurement, the monitor will indicate an alarm condition (flashing & beeping) while continuing to monitor and display the patient's current SpO2% and pulse rate. The alarm will automatically reset when the patient's condition returns to within the preset alarm parameters. Should a patient alarm condition for pulse rate occur during SpO2 monitoring, the operator may invoke "Silence Mode" by pressing the SILENCE button. This will silence the audible tone (display will continue to flash), while the practitioner attends to the patient and Monitor. Silence mode resets automatically after 30 seconds, or when the patient's condition returns to within the preset alarm parameters. If an alarm limit is violated, subsequent determinations of any type may only be made after the alarm condition is reset.
