Operator’s Manual ZM-940PA/941PA 1IntroductionThe ZM-940PA/ZM-941PA transmitter transmits ECG, respiration, SpO2, NIBP and pulse waveform from a patient to a Nihon Kohden monitor for continuous monitoring. The transmitter can change channels when connected to the QI-901PK channel writer. The front LCD displays SpO2%, NIBP, pulserate,pulsewaveformamplitude,electrodeconditionmark,batteryconditionandNIBPmeasuring mode and interval.The difference between the ZM-940PA and ZM-941PA is the transmission frequency range.ZM-940PA:608.0250MHz(channelnumber9002)to613.9750MHz(channelnumber9478)ZM-941PA:1395.0250MHz(channelnumberE002)to1399.9750MHz(channelnumberE398) 1427.0250MHz(channelnumberE502)to1431.9750MHz(channelnumberE898)Read the operator’s manual for the receiving monitor together with this manual before operation.WARNINGDo not use the same transmitter on more than one patient at the same time. Do not connect different sensors on different patients to the same transmitter.CAUTION• Do not use the same channel for different patients. If the same channel is used for two patients, the two patients’ data will be lost due to mutual modulation interference, or another patient’s data may appear on the receiving monitor screen.• Do not use transmitters of adjacent channels in a hospital. If a transmitter of an adjacent channel is used, radio waves from one transmitter affect the receiver of the adjacent channel’s transmitter and there may be interference.NOTE• To prevent interference between channels, assign a channel administrator in the hospital and only he or she should manage channel assignment.• Use Nihon Kohden parts and accessories to assure maximum performance from your instrument.• For stable signal reception, it is recommended to use a diversity antenna system on the receiving monitor. Otherwise, spike noise from transient fading of electric ﬁeld strength (for example, people moving) may interfere with the transmitter signal and may be mistaken as an arrhythmia on the receiving monitor.

2 Operator’s Manual ZM-940PA/941PA• NIBP cannot be measured on a neonate. (ECG, respiration and SpO2 can be monitored on a neonate.)• Do not diagnose a patient based on only part of the monitoring data on the transmitter or only on the data acquired by the transmitter. Overall judgement must be performed by a physician who understands the features, limitations and characteristics of the transmitter by reading this operator’s manual thoroughly and by reading the biomedical signals acquired by other instruments.• For details on the receiving monitor and upgrade information, contact your Nihon Kohden representative.

For more information, see the FDA web site. http://www.fda.gov/cdrh/safety.htmlNIBP MonitoringWARNINGBe careful when measuring NIBP on a patient with known bleeding disorders or coagulation. After NIBP measurement, there may be dot hemorrhage, or circulatory disorder by thrombus where the cuff is attached.WARNINGNIBP measurement may be incorrect in the following cases.• When using an electrosurgical unit• When there is body movement• When the pulse wave is small (insufﬁcient peripheral circulation)• Too many arrhythmias• When there is vibration• When there is a rapid blood pressure change• During CPRWARNINGWhen performing NIBP measurements in STAT mode or 5 minute intervals, periodically remove the cuff from the patient for ventilation. The skin temperature may increase at the cuff attachment site by 2 or 3°C (4 or 5°F). When measuring a patient with a fever or peripheral circulation insufﬁciency, it may cause a burn.

Operator’s Manual ZM-940PA/941PA 15CAUTIONDo 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.CAUTIONDo not wrap the cuff too tight. It may cause poor blood circulation and congestion. If the cuff is wrapped too loosely, the NIBP value may increase.CAUTIONDo not attach the cuff to the site where there is injury or inﬂammation. If the skin gets irritated or redness appears on the skin from the cuff, change the attachment site or stop using the cuff. Take extreme care on the patients with delicate skin.CAUTIONWhen using an extension hose, check that the extension hose is not bent or squeezed. Otherwise, the cuff might not inﬂate or deﬂate. If the cuff cannot deﬂate, it may cause congestion on the patient at the cuff attachment site.CAUTIONWhen performing NIBP measurement repeatedly, have a rest between measurements to recover adequate circulation.ECG 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.

16 Operator’s Manual ZM-940PA/941PASpO2 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).WARNING• 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.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.WARNINGCheck 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.

Operator’s Manual ZM-940PA/941PA 17CAUTIONNIBP and SpO2 can be measured on the same limb, but the SpO2 monitoring might not be accurate during NIBP measurement. Be careful when reading the SpO2 values.** Monitoring SpO2 during NIBP Measurement When the SpO2 probe is attached to the same limb as the NIBP cuff, the blood owdecreasesduringNIBPmeasurementand pulse wave cannot be detected and SpO2 cannot be monitored properly. When “INHIBITSpO2 DURING NIBP” on the PARAMETER SETUP screen is set to ON (factory default setting), SpO2 monitoring is paused during NIBP measurement to avoid SpO2alarmoccurrence.However,whenmonitoring SpO2 on the same limb as the NIBP, be careful when reading SpO2 values.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.CAUTIONDo 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 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.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.

18 Operator’s Manual ZM-940PA/941PACAUTIONDo 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.CAUTIONWhen a message indicates a faulty probe, stop monitoring and replace the probe with a new one.CAUTIONWhen removing a probe that is taped to the skin, do not pull the probe cable because this can damage the cable.CAUTIONNeonatal skin is delicate. Remove the probe and tape carefully and slowly.CAUTIONWhen removing the probe from the attachment tape, do not pull the sensor cable because this can damage the cable.CAUTIONDo not immerse the disposable probe in detergents or water. If the probe adhesive surface gets wet, adhesiveness becomes weak and the probe cannot be attached to the skin.CAUTIONRefer to the probe instruction manual for details.
