Maintenance, Modifications, and Repairs Fukuda Denshi is liable for the safety, reliability, and performance of its equipment only if; y Maintenance, modifications, and repairs are carried out by authorized personnel. y Components are used in accordance with Fukuda Denshi operating instructions.

Precautions about the Pacemaker z Minute ventilation rate-adaptive implantable pacemakers can occasionally interact with the bedside monitor including this unit and diagnostic equipment, causing the pacemakers to pace at their maximum programmed rate. The cardiac monitoring and diagnostic equipment may possibly send wrong information. If such event occurs, please disconnect the cardiac monitoring and diagnostic equipment, or follow the procedures described in the operation manual of the pacemaker. Reference “Minute Ventilation Rate-Adaptive Pacemakers” FDA alerts health professionals that minute ventilation rate-adaptive WARNING implantable pacemakers can occasionally interact with certain cardiac monitoring and diagnostic equipment, causing pacemakers to pace at their maximum programmed rate. [October 14, 1998 (Letter: www.fda.gov/cdrh/safety.html) – FDA] z 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 equipment.

iv

Non-Explosion Proof Never operate the equipment in the presence of flammable anesthetics, high of oxygen, or inside hyperbaric chamber. Also, do not operate D A N G E R concentration the equipment in an environment in which there is a risk of explosion. Explosion or fire may result.

Defibrillation Safety z When defibrillating, keep away from the electrodes or medicament applied to the patient chest. If this is not possible, remove the electrodes or medicament before defibrillating. If the defibrillator paddles directly contact the electrodes or medicament, electrical shock may result by the discharged energy.

W A R N I N G z When defibrillating, make sure that the electrodes, sensor cables, or relay cables are firmly connected to the device. Contacting the metal part of the disconnected cable may result in electrical shock by the discharged energy.

z When defibrillating, do not touch the patient and the metal part of the device or cables. Electric shock may result by the discharged energy.

Precautions about the Mason-Likar System ●ECG Recording by the Mason-Likar System The 12-lead ECG recorded with the torso placement of the limb leads (Mason-Likar 12-lead system) may differ from the standard 12-lead ECG. Moreover, waveforms may differ somewhat also in a supine position and a C A U T I O N standing position (sitting position). We recommend to carry out the recording of the ECG by taking into consideration the waveform differences according to electrode positions or postures.

●Electrode Placement NOTE

To reduce the waveform differences from the standard 12-lead, we recommend that the torso placement of the R and L electrodes be near as possible to each arm, in the infraclavicular fossae, within the area unaffected by myoelectricity.

v

Electrosurgery Safety The monitoring system contains protection against interference generated by electrosurgical instruments. However, operating conditions, surgery site with respect to the location of ECG electrodes, or the type of instrument used, may cause noise on the ECG. The noise is generated at the tip of an electrical knife and is difficult to completely eliminate because of the frequency components of the ECG. To reduce electrosurgical interference, take the following precautions: Location Locate the electrosurgical unit as far as possible from this unit and the patient cable. This will help reduce interference on the ECG through the monitor or cables.

WARNING

Power Supply Connect the electrosurgical unit to a power supply that is different from that of the monitor. This will help prevent interference through the power cable. Electrode Placement The amount of interference is considerably different depending on the electrode position and surgery site. Place the ECG electrodes as far away as possible from the surgery site. Do not place electrodes in the path between the surgery site and the ground plate. If the electrodes are placed in this path, the amount of interference will be quite large. Position (+) and (–) electrodes as close as possible to each other. Ground Plate When using electrosurgical instruments, make sure the contact between the patient and the ground plate is secure. If the connection is incomplete, the patient may suffer a burn at the electrode site.

Precautions about Magnetic Resonance Imaging z Do not operate this equipment in magnetic resonance imaging (MRI) environments. z When conducting MRI test, remove the electrodes and sensors connected WARNING to the patient (test subject). The local heating caused by the induced electromotive force may cause burn injury to the patient (subject). For details, refer to the operation manual for the MRI testing device.

vi

Precautions about Connections to Peripheral Devices In the interest of safe and sufficient performance of this equipment, the connection of other manufacturers’ equipment to the monitor is not authorized, unless the connection is explicitly approved by Fukuda Denshi. It is the user’s responsibility to contact Fukuda Denshi to determine the compatibility and warranty status of any connection made to another manufacturer’s equipment. For the connector with mark, only the peripheral devices specified by Fukuda Denshi should be connected with the given procedure. Use of an WARNING unspecified device may cause electric shock to the patient and/or operator due to excessive leakage current. z For safety reasons, the peripheral device connector on this unit (analog output connector) is insulated from the circuit applied to the patient. z The circuit connected to this unit on the peripheral side is not necessarily CAUTION insulated. Therefore, since touching the peripheral directly may result in electric shock to the patient, always position the peripheral away from the patient. When connecting peripheral devices to this unit, it is the user’s responsibility to verify that the overall system complies with IEC 60601-1-1, “Collateral Standard: Safety Requirements for Medical Electrical Systems”.

Accessories and Optional Accessories Use only the cables specified by Fukuda Denshi.

WARNING

y Use of other cables may result in increase in emission (unnecessary generation of electromagnetic energy from this unit) or decrease in immunity (resistance characteristics to electromagnetic interference generating from other device). y We cannot assure the performance of this unit when other cables are used.

vii

Precautions about the HS-8000 System Be careful when connecting to other device.

D A N G E R Danger such as electric shock may result to the patient and operator. z Do not connect unit or cable not authorized by Fukuda Denshi to any I/O connector. If done so by mistake, the HS-8000 system cannot deliver its maximum performance and the connected units may be damaged, resulting in a safety hazard. z If this unit is used under the condition where operating environment is not satisfied, this unit can neither deliver its maximum performance nor ensure safety such as damage to this unit. z Objective and constant arrhythmia detection is possible through the fixed algorithm incorporated in this monitor. However, excessive waveform morphology change, motion artifact, or the inability to determine the waveform pattern may cause an error, or fail to make adequate detection. Therefore, physicians should make final decisions using manual recording, alarm recording and recall waveform for evaluation. z Be careful when setting the "SpO2 Averaging" duration as the SpO2 alarm is based on the displayed SpO2 value which is averaged from the duration set in "SpO2 Averaging". The alarm occurrence time will be affected or may not occur for the transient value of SpO2 depending on the set duration. z When measuring the SpO2 of patient with high fever or peripheral circulatory insufficiency, check the sensor attachment periodically and change the attachment site. The temperature of attachment site will rise 2 to 3°C due to the sensor heat which may result in burn injury. z For the following case, accurate measurement may not be possible.

WARNING

y Patient with excessive abnormal hemoglobin (COHb, MetHb) y Patient with the pigment injected to the blood y Patient receiving CPR treatment y When a sensor is applied to a limb with NIBP cuff, arterial catheter, or intracatheter y When measuring at site with venous pulse y Patient with body motion y Patient with small pulse

z Before the Non-Invasive Blood Pressure measurement, make sure the patient classification ( Adult ・ Child ・ Neonate) is properly selected on the Patient Admit display in the main unit. Otherwise, correct measurement cannot be performed, and injury such as congestion may result. z Always consider the circumference of the intubation tube when using the airway adapter. If inappropriate airway adapter is used for a patient with low ventilation, CO2 may mix in to the inspired air resulting in incorrect measurement, or apnea detection may become difficult. z The analog signal has a delay output according to the filter mode setting on the main unit. (For ECG, the delay is approximately 15 to 35 msec, and in BP, approximately 35 to 50 msec.) When connecting to any equipment that uses a vital signal as a trigger signal, for instance, IABP, make sure that the filter selection and delay time of the HS-8000 series meet the specification of such equipment. z The delay time varies depending on the types of waveform, or caused interference. z The QRS SYNC signal has a delay output (the delay time is less than 100 ms). The delay time varies depending on the filter mode setting on the main unit or type of the waveform input. z When the QRS SYNC signal is input to any external devices, make sure that the delay time of the HS-8000 series is within the acceptable range of such device.

viii

z HS-8000 System y Use only the accessories specified for this unit. Otherwise, proper function cannot be executed. y For quality improvement, specifications are subject to change without prior notice. y This equipment is intended to be used for only one patient.

z ECG Monitoring

CAUTION

y Use only the specified relay cables, lead cables, and electrodes. y The conductive parts of electrodes and associated connectors for applied parts, including the neutral electrode, should not contact other conductive parts including earth. y The indication for continuous use of the electrode is about one day. y Replace the electrode if the skin contact gets loosen due to perspiration. y When an electrode is attached to the same location for a long period, some patients may develop skin irritation. Check the patient’s skin condition periodically and change the electrode site as required. y Even the ECG waveform has a minimum threshold level, QRS Automatic Detection may not be automatically conducted. y The following EGC may not be automatically detected. ・ The QRS amplitude is low and the QRS width is extremely wide. ・ The interference of artifacts such as EMG or body motion is large. ・ Loud noise is generated by electrosurgical instruments. y There are some cases when the pacemaker pulse can not be detected depending on the pacemaker type, pulse voltage, pulse width, electrode lead type (unipolar, bipolar), or electrode placement which causes the pacemaker pulse amplitude to decrease and disables the pacemaker pulse detection. y If signals similar to a pacemaker pulse are present, such as electric blanket noise or excessive AC frequency noise, these may be erroneously detected and displayed as a pacemaker pulse. y When the spontaneous QRS and pacemaker pulse overlaps (as in a fusion beat), QRS detection will be suspended and the heart rate will be reduced. y If a pacemaker pulse is continuously detected due to AC frequency interference, QRS detection will be suspended and the heart rate will be reduced.

z Arrhythmia Analysis y For proper arrhythmia detection and ECG monitoring, verify proper electrode placement, lead selection, and ECG waveform size. If necessary, turn ON the AC filter. Improper electrode placement, lead selection, and ECG waveform size can cause errors in detection.

z Respiration Monitoring y When a defibrillator is used during respiration monitoring, a large offset voltage will be placed on the ECG electrodes, which may cause interruption of monitoring for a few seconds.

z SpO2 Monitoring

y If the nail is rough, dirty, or manicured, accurate measurement will not be possible. Change the finger or clean the nail before attaching the probe and sensor. y If irritation such as skin reddening appears with the sensor use, change the attachment site or stop using the sensor. y When attaching the sensor with tape, do not wrap the tape too tight. At the same time, check the blood flow constantly so that congestion is not generated at the peripheral. y Even a short duration of attachment may inhibit the blood flow and generate compression necrosis and burn injury. SpO2 may not be measured correctly because of inhibition of blood flow. y Change the sensor attachment site constantly (every 4 hours). As the temperature of sensor attachment site normally rises 2 to 3°C, compression necrosis and burn injury may generate. y As the skin of neonate/low birth weight infant is immature, change the sensor attachment site more frequently depending on the condition. y Direct sunlight to the sensor area can cause measurements error. Place a black or dark cloth over the sensor. y When not measuring, unplug the relay cable and sensor from the SpO2 connector. Otherwise, the outside light may affect to falsely display measurements.

ix

y Precautions for Reusable Sensor ・ The light-emitting part of the sensor should be over the root of the fingernail. Do not insert the finger too far into the sensor as it may hurt the patient. ® ・ Nellcor sensor, DS-100A is intended for use on finger of adults weighing over 40 kg (approximate). Do not use them on children or neonates. Also do not apply them on the thumb or foot. ・ The DS-100A is not designed for long-term use. Remove the sensor every 4 hours. If any inhibition is detected in tissue blood flow, replace it or move the sensor to another finger. y Precautions for Single-Patient-Use Type Sensor ・ Do not secure the adhesive tape too tight as it may obstruct the blood flow. ・ Do not use the sensor on patients who exhibit allergic reactions to the adhesive tape. ® ・ Nellcor sensor OXISENSORⅢ, MAX Fast is a sterilized product which can be reused on the same patient as long as it is still adhesive to the skin. ® ・ Masimo LNOP sensor can be reused on a same patient if the light emitting and receiving part is clean, and if it is still adhesive to the skin. Do not reuse it on other patient. ® ・ Nellcor sensor OXISENSORⅢ, MAX Fast can be continuously used on the same site for maximum 8 hours only if the applied part is periodically checked and observed that the applied part is correctly attached and no abnormality on the skin and adherence of the sensor should be found. ・ Do not resterilize. ・ After using this unit, dispose it. Even if this unit is unused, dispose it once it is opened. ® y For Masimo sensor, check the sensor attachment site constantly (in every 4 hours when the reusable sensor is used, and at least every 8 hours when the disposable sensor is used). Be especially careful of a patient with bad perfusion. If the sensor attachment site is not changed constantly, skin irritation or skin necrosis due to compression may be developed. For the patient with bad perfusion, check the sensor attachment position at least every 2 hours.

CAUTION

z NIBP Monitoring y Select the appropriate cuff size which best fits the arm circumference. If the cuff size is inappropriate, it may cause measurement error. y Do not use a cuff which is worn out. The cuff may burst during inflation. y Make surethat the cuff hose connection is secure. If there is any air leakage, correct NIBP measurement cannot be performed. y Correct NIBP measurement cannot be performed if artificial heart lung machine is used or if the pulse is difficult to detect. y Correct NIBP measurement cannot be performed if artificial heart lung machine is used or if the pulse is difficult to detect. y Pay attention when measuring the NIBP of patient with bleeding disorders or hyper coagulation. The cuff inflation may cause petechia or circulatory failure by the blood clot. y Always display the NIBP numeric data box on the display in the main unit when NIBP is measured. If the NIBP start/stop key of HS-8000 is pressed when the NIBP Numeric Data Box is not displayed, although measurement is performed, the measurement result will not be displayed. y Do not apply the cuff to the arm or thigh where vein is secured. The blood may backflow causing the chemical injection to cease. y During measurement, check that the cuff and air hose are not either squashed or bent. If the exhaust is not properly conducted and the air remains in the cuff over a long period, the blood circulation will be blocked and congestion may occur. y Check the patient’s condition constantly while measuring over a long period of time with interval of 2.5 minutes or less. Also, periodically check the blood circulation while performing periodic measurement over a long period of time. Congestion or rash may occur at the measuring site. y The following factors may affect the NIBP value. ・Body motion, arrhythmia, convulsion ・Continuous noise such as cardiac massage ・Periodic electromagnetic noise y For the following situation, measurements will be terminated. When the measurement time has exceeded 160 seconds for adult and child, 80 seconds for neonate. When the inflation value has exceeded 300mmHg for adult, 210mmHg for child, and 150mmHg for neonate.

z BP Monitoring y The zero balance procedure is required for the following case. ・ When starting the measurement. ・ When the position of the heart has changed due to body movement. ・ When the transducer position has changed. ・ When measuring for a long period of time and there is a possibility of measurement error due to change in ambient temperature, etc. ・ When a connector is connected / disconnected, or a transducer is replaced.

z CO2 Monitoring

y On the DS-8500 system, when the Multigas Unit MGU-800 series is used, CO2 measurement by the GAS Unit which is connected to the HS-8000 series (for example the Capnostat 5 using HPD-800) cannot be performed. y The disposable airway adapter should be opened just before use. Do not sterilize it or it will become unusable. y Do not reuse the disposable airway adapter. y Do not sterilize the reusable airway adapter using autoclave methods.

z CO2 Monitoring by Gas Unit I/F HPD-800

y The airway adapter should be attached with the thicker side facing to the patient. If attached oppositely, it may damage the CO2 sensor or airway adapter.

z Temperature Monitoring

CAUTION

y Do not reuse the probe cover. Use it for a patient only and dispose it after using it.

z Maintenance y Clean the equipment and relay cables frequently so stains can be removed easily. y To prevent injury, it is recommended to wear gloves when cleaning the equipment. y Do not allow liquids or cleaning solution to enter the equipment or connectors. y Do not use organic solvents, thinner, toluene or benzene to avoid damaging the resin case. y Do not polish the housing with abrasive or chemical cleaner. y When sterilizing the entire room using a spray solution, pay close attention not to have liquids get into the monitor or connectors. y Use only neutral detergent to clean the housing. Do not use chemical cloth, scrub brush, abrasive, polishing powder, hot water, volatile solvent and chemicals (cleanser, thinner, toluene, benzine, benzol, and synthetic detergent for house and furniture), or sharp-edged tools. The surface resin coating may be damaged, resulting in discoloration, scratches, and other problems. y Do not open the housing. y Avoid alcohol or other liquids from getting into the device. y If you accidentally wet the device, dry it completely and verify it operates safely before usage. y Replace the periodic replacement parts periodically as specified.
