12 Operator’s Manual ZM-920PA/921PA/930PA/931PAFor Patients Using Implantable PacemakerWARNINGInteraction Between Minute Ventilation Rate-Adaptive Pacemakers and Cardiac Monitoring and Diagnostic EquipmentThe bioelectric impedance measurement sensor of a minute ventilation rate-adaptive implantable pacemaker may be affected by transmitter which is connected to the same patient. If this occurs, the pacemaker may pace at its maximum rate and the transmitter may give incorrect data to the monitor. If this occurs, disconnect the electrode leads from the patient or change the setting on the pacemaker by referring to the pacemaker’s manual. For more details, contact your pacemaker representative or Nihon Kohden representative.Output SignalWARNINGDo not use the output signal from the receiving monitor as the synchronization signal for other equipment such as IABP, MRI, echocardiography or defibrillator. There may be time delay between the monitor and the other equipment caused by waveform transmission delay and spike noise may interfere on the output signal and be mistaken as a trigger.
Operator’s Manual ZM-920PA/921PA/930PA/931PA 13ECG MonitoringCAUTIONOnly use Nihon Kohden specified electrodes and electrode leads. When other type of electrodes or electrode leads are used, the “CHECK ELECTRODES” message may be displayed and monitoring may stop.CAUTIONWhen the “ELECTRODE OFF” or “CHECK ELECTRODE” message is displayed on the receiving monitor, ECG is not monitored properly and the ECG alarm does not function. Check the electrode, electrode leads, and if necessary, replace with new ones.SpO2 MonitoringWARNINGSpO2 measurement may be incorrect in the following cases.• When the patient’s carboxyhemoglobin or methemoglobin increases abnormally.• When dye is injected in the blood.• When using an electrosurgical unit.• During CPR.• When measuring at a site with venous pulse.• When there is body movement.• When the pulse wave is small (insufficient peripheral circulation).
14 Operator’s Manual ZM-920PA/921PA/930PA/931PAWARNINGCheck the circulation condition by observing the skin color at the measurement site and pulse waveform. Change the measurement site every 8 hours for disposable probes and every 4 hours for reusable probes (every 8 hours for TL-630T/TL-631T series probe). 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.• Patient with a fever• Patient with peripheral circulation insufficiency• Neonate or low birth weight infant with delicate skin• Patient who is receiving photodynamic therapy** Photodynamic therapy is a treatment to remove the affected tissue by using a photosensitizing agent and exposing the tissue to light. This treatment has a side effectofphotosensitivityandthelightfromthengerprobesensormaycausea burn. This probe uses two light wavelengths in the range from 650 to 950 nm. The maximum light intensity is less than 5.5 mW/sr.WARNINGWhen not monitoring SpO2, disconnect the SpO2 cable from the transmitter. Otherwise, noise from the probe sensor may interfere and incorrect data is displayed on the screen.
Operator’s Manual ZM-920PA/921PA/930PA/931PA 15WARNING• When using the TL-201T finger probe, do not fasten the probe and cable to the finger by wrapping with tape. This may cause burn, congestion or pressure necrosis from poor blood circulation.• When using probes other than the TL-201T finger probe, 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.CAUTIONWhile a patient is on medication which causes vasodilation, the pulse waveform may change and in rare cases the SpO2 value might not be displayed.CAUTIONNormal external light does not affect monitoring but strong light such as a surgical light or sunlight may affect monitoring. If affected, cover the measuring site with a blanket.CAUTIONIf the attachment site is dirty with blood or bodily fluids, clean the attachment site before attaching the probe. If there is nail polish on the attachment site, remove the polish. Otherwise, the amount of transmitted light decreases, and measured value may be incorrect or measurement cannot be performed.
16 Operator’s Manual ZM-920PA/921PA/930PA/931PACAUTIONDo not use a probe which is deteriorated by aging. Accurate measurement cannot be performed.CAUTIONDo not use a damaged or disassembled probe. It causes incorrect measurement and may injure the patient.CAUTIONThe disposable probe is not sterilized. Use the disposable probe only for a single patient. Never reuse the disposable probe for another patient because it causes cross infection.CAUTIONIf the skin gets irritated or redness appears on the skin from the probe, change the attachment site or stop using the probe. Take extreme care for the patients with delicate skin.CAUTIONDo not pull or bend the probe cable, and do not put caster feet on the probe cable. Do not immerse the probe cable in chemical solutions or water. Failure to follow these instructions may cause cable discontinuity, short circuit, skin burn on the patient and incorrect measurement data. Replace any broken probe with a new one.CAUTIONWhen 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.

The heart rate is also measured. When 3 leads are used, one channel ECG waveform of lead II can be displayed on the receiving monitor. Refer to the operator’s manual of the monitor for details.WARNINGInteraction 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 transmitter which is connected to the same patient. If this occurs, the pacemaker may pace at its maximum rate and the transmitter may give incorrect data to the monitor. If this occurs, disconnect the electrode leads from the patient or change the setting on the pacemaker by referring to the pacemaker’s manual. For more details, contact your pacemaker representative or Nihon Kohden representative.* 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
