EMC RELATED CAUTION

This equipment and/or system complies with the International Standard IEC60601-1-2 for electromagnetic compatibility for medical electrical equipment and/or system. However, an electromagnetic environment that exceeds the limits or levels stipulated in the IEC60601-1-2, can cause harmful interference to the equipment and/or system or cause the equipment and/or system to fail to perform its intended function or degrade its intended performance. Therefore, during the operation of the equipment and/or system, if there is any undesired deviation from its intended operational performance, you must avoid, identify and resolve the adverse electromagnetic effect before continuing to use the equipment and/or system.

The following describes some common interference sources and remedial actions:

1.Strong electromagnetic interference from a nearby emitter source such as an authorized radio station or cellular phone:

Install the equipment and/or system at another location if it is interfered with by an emitter source such as an authorized radio station. Keep the emitter source such as cellular phone away from the equipment and/or system.

2.Radio-frequency interference from other equipment through the AC power supply of the equipment and/ or system:

Identify the cause of this interference and if possible remove this interference source. If this is not possible, use a different power supply.

3.Effect of direct or indirect electrostatic discharge:

Make sure all users and patients in contact with the equipment and/or system are free from direct or indirect electrostatic energy before using it.

4.Electromagnetic interference with any radio wave receiver such as radio or television:

If the equipment and/or system interferes with any radio wave receiver, locate the equipment and/or system as far as possible from the radio wave receiver.

In IEC 60601-1-2 Medical Electronic Equipment, Part 1: General Requirements for Safety, 2. Collateral Standard: Electromagnetic compatibility-Requirements and test. Section 36. 202. 2 Radiated radiofrequency electromagnetic fields, PATIENT COUPLED EQUIPMENT and/or SYSTEMS applicable IMMUNITY test methods are under consideration at SC62A/WG13. The 3 V/m IMMUNITY level may be inappropriate especially when measuring SpO2 because physiological signals can be much smaller than those induced by a 3 V/m electromagnetic field.

When measuring SpO2, various interference may produce false waveforms which look like pulse waveforms. SpO2 value and pulse rate may be measured from these false waveforms, causing the alarm to function improperly.

When installing the monitor, avoid locations where the monitor may receive strong electromagnetic interference such as radio or TV stations, cellular phone or mobile two-way radios.

WARNING

Interaction Between Minute Ventilation Rate-Adaptive Pacemakers and Cardiac Monitoring and Diagnostic Equipment*

The bioelectric impedance measurement sensor of a minute ventilation rate-adaptive implantable pacemaker may be affected by cardiac monitoring and diagnostic equipment which is connected to the same patient. If this occurs, the pacemaker may pace at its maximum rate and give incorrect data to the monitor or diagnostic equipment. If this occurs, disconnect the monitor or diagnostic equipment from the patient or change the setting on the pacemaker by referring to the pacemaker’s manual. For more details, contact your pacemaker distributor or Nihon Kohden distributor.

*Minute ventilation is sensed in rate-adaptive pacemakers by a technology known as bioelectric impedance measurement (BIM). Many medical devices in addition to pacemakers use this technology. When one of these devices is used on a patient with an active, minute ventilation rate-adaptive pacemaker, the pacemaker may erroneously interpret the mixture of BIM signals created in the patient, resulting in an elevated pacing rate.

For more information, see the FDA web site. http://www.fda.gov/cdrh/safety.html

WARNING

•When using a defibrillator together with the monitor, use Ag/AgCl electrodes. Other types of electrodes, stainless steel in particular, adversely affect the ECG waveform by slowing the baseline recovery on the monitor and result in no monitoring immediately following defibrillation.

•False heart rate indicators may occur with certain pacemakers because of electrical overshoots.

•Pacemaker patients can only be monitored when the pace program is activated.

•Keep pacemaker patients under close observation. The pacemaker rate may be counted during cardiac arrest and certain arrhythmias. Do not rely only on the monitor.

1. GENERAL

CAUTION

•Use only Nihon Kohden products and specified parts and accessories. When other type of electrodes are used, the “CHECK ELECTRODE” message may be displayed and monitoring may stop.

•Do not reuse disposable electrodes.

•When using the electrodes with DIN type lead, use only the Vitrode V or N electrodes. If other electrodes are used, the electrode lead may not be properly connected and ECG monitoring may be unstable.

•If the contact is bad even before the expiration date printed on the package, replace the electrode with a new one.

•When the “CHECK ELECTRODE” message is displayed, ECG is not monitored properly. Check the electrode, electrode leads and connection cord, and if necessary, replace it with a new one.

•Turn the pacing spike detection to On when monitoring a pacemaker patient. Otherwise QRS and pacemaker spike may not be distinguished and pacemaker failure may not be recognized.

1. GENERAL

SpO2 Monitoring

WARNING

•Measurement may not be correct in the following cases.

·When the oxyhemoglobin or methemoglobin (HbCO, Met Hb) increases abnormally.

·When dye is injected in the blood.

·During CPR.

·When there is body movement.

·When the pulse wave is small.

•Check the circulation condition by observing the skin color of the measuring site and pulse waveform. Change the measuring site every 8 hours for disposable probes and every 4 hours for reusable probes. The skin temperature may increase at the attached site by 2 or 3°C (4 or 5°F) and cause a burn or pressure necrosis. When using the probe on the following patients, take extreme care and change the measurement site more frequently according to symptoms and degree.

·A patient with a fever

·A patient with peripheral circulation insufficiency

·Neonate or low birth weight infant with delicate skin

•To avoid poor circulation, do not wrap the tape too tight. Check the blood circulation condition by observing the skin color and congestion at the skin peripheral to the probe attachment site. Even for short-term monitoring, there may be burn or pressure necrosis from poor blood circulation, especially on neonates or low birth weight infants whose skin is delicate. Accurate measurement cannot be performed on a site with poor peripheral circulation.

•When not monitoring SpO2, disconnect the SpO2 connection cord from the bedside monitor. Otherwise, noise from the probe sensor

may interfere and incorrect data is displayed on the screen.

•Do not use the probe during MRI examination because it may cause skinburn on the probe attachment area. For details, follow the MRI operator’s manual.

1. GENERAL

CAUTION

•Turn off the power of cell telephones, small wireless devices and other devices which produce strong electromagnetic interference. Otherwise, the waveforms and measurements are affected by such interference and the displayed data may be incorrect.

•Only use the specified probes. Otherwise SpO2 cannot be monitored properly.

•Do not use a disassembled or damaged probe because measured data may be incorrect.

•Do not use the probe over its stated lifetime. Otherwise the SpO2 measurement accuracy cannot be guaranteed.

•If the skin gets irritated by the tape, change the attachment site.

•Do not attach the probe to the same limb that is used for NIBP measurement or an IBP catheter.

•Normally external light does not affect monitoring, however, strong light such as an operating lamp or sunlight may affect monitoring. If affected, cover the measuring site with a blanket.

•When attached, make sure that the photo emitter and the detector of

the probe face each other. Otherwise, SpO2 cannot be measured properly.

•Do not reuse the disposable probes for another patient.

•Disposable probes are not sterilized. To sterilize the probe, refer to the “Sterilizing the Disposable Probe” in Section 12.

•When the probe is attached on an appropriate site with sufficient circulation and the error message confirming the probe attachment repeatedly appears, the probe may be deteriorated. Replace it with a new one.

•When the probe or SpO2 connection cord failure message appears on the screen, replace it with a new one. Otherwise SpO2 data may not be accurate.

•When the attachment site is wet with blood or when the patient has nail polish on, remove dirt and nail polish before attaching the probe. The transmitted light may decrease due to blood or nail polish and the measurement data may be incorrect.

•To minimize body movement for stable SpO2 monitoring, fasten the cable with the provided adhesive tape.

•Do not pull or bend the probe cable, and do not put caster feet on the probe cable. Do not immerse the probe cable in detergents or water. Failure to follow these cautions may cause cable discontinuity, short circuit, skin burn on the patient and incorrect measurement data.

Replace any broken probe with a new one.

•When using a disposable probe, be careful when removing the foam tape from neonatal skin.

•When removing a disposable probe that is taped to the skin, do not pull the cable part of the probe because this can damage the probe’s cable connection.

•Refer to the probe instruction manual for details.

1. GENERAL

NIBP Monitoring

WARNING

•NIBP measurement on a sickle cell anemia patient may cause a thrombus.

•When attaching the cuff to a premature infant at an early stage after birth, periodically change the cuff position to avoid possible skin erosion and fissure.

•While performing STAT (continuous) measurements many times without a pause, periodically check the blood vessels and limb for adequate circulation.

•When performing long term measurements at intervals less than 2.5 minutes, periodically check the state of the patient, blood vessels and limb for adequate circulation.

CAUTION

•Only use the specified cuff. Otherwise NIBP monitoring cannot be performed properly or the monitor may be damaged.

•Select the cuff which fits each patient. If the cuff size is not correct, measurement may not be completed or the result may be erroneous due to the different deflation speed of the cuff.

•The YP-950T/951T/952T/953T/954T/955T reusable cuffs contain natural rubber latex which may cause allergic reactions.

•Do not reuse the disposable cuff.

•Disposable cuffs are not sterilized. If necessary, sterilize the cuff using glutaraldehyde solution.

•The non-sterilized disposable cuffs for neonates cannot be sterilized. If necessary, use the sterilized disposable cuffs for neonates.

•Never sterilize the disposable cuff for neonates.

•Do not wrap the cuff on an arm or thigh which is used for injection. NIBP measurement on an arm or thigh which is used for injection may cause reflux of blood and stop injection.

•Confirm that the air hoses are firmly connected between the sockets and hoses of the cuff. If not connected properly (the air hose connector clicks and the red color of the NIBP socket is completely hidden behind the air hose connector when properly inserted into the socket), the cuff cannot be correctly identified and air leakage will cause incorrect NIBP data or no data.

•When too much pressure is applied to the cuff, or the hose is folded or kinked, the “NIBP SAFETY VALVE OPEN” message appears on the screen and NIBP monitoring may be stopped. Remove the cause, wait for 40 seconds, check that the message disappears, then measure again.

•If the hose is folded or squeezed, it will cause incorrect NIBP data due to the air pressure noise.

•Do not rely only on the PWTT to monitor blood pressure changes. When it is necessary to monitor critical blood pressure change, set the appropriate interval for NIBP measurement.

1. GENERAL

•When the delta PWTT threshold is too short for a patient, NIBP measurement may be performed too frequently. If this occurs, change the delta PWTT threshold to a longer time.

•The PWTT may be incorrect when there is too much arrhythmia or noise.

•In the following cases, PWTT may trigger too many or no NIBP measurements. Check the patient condition. If necessary, change the delta PWTT threshold or set PWTT to Off.

·Rapid blood pressure change with vasoreflex due to vasoactive drugs, such as phenylephrine and nicardipine.

·Unstable pulse wave due to poor peripheral circulation.

·Too many arrhythmias.

·Patient movement.

·Noise on ECG.

·SpO2 measurement on foot of a child.

•Do not measure NIBP with PWTT on a neonate because circulation of a neonate changes rapidly.

Maintenance

CAUTION

•Do not disassemble the monitor. Disassembly must be performed by a qualified service personnel.

•Fuses must be replaced by a qualified service personnel.

•Do not use volatile liquids such as thinner or benzine, because these will cause the materials to melt or crack.

•Before cleaning the monitor, turn the monitor power off and disconnect the power cord from the AC SOURCE power cord socket on the right side panel.

•After cleaning, make sure that the monitor is completely dried.

•Wipe the monitor thoroughly after disinfecting it with spray.

•The bedside monitor is not waterproof. Be careful not to let any water get inside the monitor.
