Operator’s Manual  ZM-540PA/541PA  1Intended UseGeneralThe ZM-540PA and ZM-541PA transmitter transmits ECG, respiration and pulse waveforms, SpO2 and NIBP data from a patient to a Nihon Kohden monitor for continuous monitoring. The front LCD displays ECG (or pulse wave), numeric values of monitoring parameters, NIBP measuring mode and interval, messages and battery condition.* It also displays the compressed waveform and numeric data of the latest 10 minutes.*  Essential performance of this transmitter.The difference between the ZM-540PA and ZM-541PA is the transmission frequency range.ZM-540PA: 608.0250 MHz (channel number 9002) to 613.9750 MHz (channel number 9478)ZM-541PA: 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)The transmitter channel can be changed with a QI-901PK channel writer.Read the operator’s manual for the receiving monitor together with this manual before use.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 two transmitters with adjacent channels in the same hospital. If transmitters with adjacent channels are used, their radio waves interfere with each other.CAUTIONBe aware that signal loss and artifact may occur because of the multipath cancellation* when using a transmitter.*  Multipath Cancellation (Standing Wave Interference)  When a radio wave reflects off a surface, there may be some points in the room where the
2  Operator’s Manual  ZM-540PA/541PAreflected and direct waves are exactly out of phase. At these points in the room, the reflected and direct waves cancel each other out so that the signal strength is 0. This is called “multipath cancellation” or “standing wave interference”. Locations where signal loss occurs are called “null spots”. If the transmitter is moving or nearby people or objects are moving, null spots can occur anytime and anywhere.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.•  For details on antennas and antenna construction, contact your Nihon Kohden representative. You can also refer to the Telemetry System Installation Guide.•  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 judgment 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.Receiving MonitorAny Nihon Kohden receiving monitor (central monitor with multiple patient receiver) can receive signals from this transmitter as long as the protocol version and channel setting are the same on the receiving monitor and transmitter.NOTE•  For details on the receiving monitor and upgrade information, contact your Nihon Kohden representative.•  The transmitter does not give any patient alarm, only a “no battery” alarm. Patient alarms must be managed on the receiving monitor.

10  Operator’s Manual  ZM-540PA/541PACAUTIONBe aware that signal loss and artifact may occur because of the multipath cancellation* when using a transmitter.*  Multipath Cancellation (Standing Wave Interference)  When a radio wave reflects off a surface, there may be some points in the room where the reflected and direct waves are exactly out of phase. At these points in the room, the reflected and direct waves cancel each other out so that the signal strength is 0. This is called “multipath cancellation” or “standing wave interference”. Locations where signal loss occurs are called “null spots”. If the transmitter is moving or nearby people or objects are moving, null spots can occur anytime and anywhere.CAUTIONTurn off the power of mobile phones, small wireless devices and other devices which produce strong electromagnetic interference around a patient (except for devices allowed by the hospital administrator). Radio waves from devices such as mobile phones or small wireless devices may be mistaken as pulse waves and the displayed data may be incorrect.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 two transmitters with adjacent channels in the same hospital. If transmitters with adjacent channels are used, their radio waves interfere with each other.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-540PA/541PA  11BatteryCAUTIONBattery replacement must be performed by the operator. When replacing the batteries of a transmitter that is currently used for a patient, disconnect the electrode leads from the transmitter before replacing batteries or do not touch the patient during replacement.CAUTIONRefer to the battery and battery charger manuals for details on handling the batteries.Transmitter Channel ManagementWARNINGThe following actions must be taken to properly receive the transmitter signal of the correct patient on the receiving instrument. Otherwise, there may be signal loss or signals may mix causing a serious accident, such as monitoring a different patient.•  Assign a channel administrator in the hospital and only he or she should manage channel assignment.•  The channel administrator must manage the channels in the facility so that there is no signal interference.•  When the transmitter channel is changed, the channel administrator must check that the channel on the receiving monitor is also changed and the signal is properly received.•  The channel administrator must replace the channel number label on the transmitter with the new one after changing the channel.
12  Operator’s Manual  ZM-540PA/541PAFor Patients Using Implantable PacemakerWARNINGInteraction 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.htmlECG MonitoringCAUTIONOnly use Nihon Kohden specified electrodes and electrode leads. When other electrodes or electrode leads are used, the “CHECK ELECTRODES” message may appear and monitoring may stop.CAUTIONWhen the “ELECTRODE OFF” or “CHECK ELECTRODES” 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.
Operator’s Manual  ZM-540PA/541PA  13SpO2 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).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.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.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
14  Operator’s Manual  ZM-540PA/541PAWARNINGWhen monitoring SpO2 of a patient who is receiving photodynamic therapy, the light from the finger probe sensor may cause a burn. Photodynamic therapy uses a photosensitizing agent that has a side effect of photosensitivity.CAUTIONRefer to the probe instruction manual for details.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.CAUTIONNIBP 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 flow 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.CAUTIONWhen a message indicates a faulty probe, stop monitoring and replace the probe with a new one.
Operator’s Manual  ZM-540PA/541PA  15CAUTIONDo not use a damaged or disassembled probe. It causes incorrect measurement and may injure the patient.CAUTIONDo not use a probe which is deteriorated by aging. Accurate measurement cannot be performed.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.CAUTIONDo not pull or bend the probe cable, and do not put caster feet on the probe cable. Do not immerse the disposable 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.
16  Operator’s Manual  ZM-540PA/541PANIBP 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.CAUTIONDo 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.
Operator’s Manual  ZM-540PA/541PA  17CAUTIONWhen performing NIBP measurement repeatedly, have a rest between measurements to recover adequate circulation.MaintenanceCAUTIONThis transmitter is not waterproof. If detergent or liquid spills into the transmitter, stop cleaning or disinfecting it and contact your Nihon Kohden representative.

Operator’s Manual  ZM-540PA/541PA  39Attaching Electrodes, SpO2 Probe and NIBP Cuff to the PatientThe transmitter can be attached to an arm of the patient or placed on the bedside. The required length of the electrode leads and SpO2 probe cable depends on how the transmitter is to be attached to the patient.NOTEMonitoring SpO2 during NIBP MeasurementWhen the SpO2 probe is attached to the same limb as the NIBP cuff, the blood flow 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 NIBP, be careful when reading SpO2 values.When monitoring SpO2 is important, attach the probe to the limb to which theNIBP cuff or catheter is not attached.Attachment ExamplesWhen transmitter is attached on an arm When transmitter is placed on a bedsideNOTEWhen placing the transmitter on a bedside, place it on a stable and flat place. If the transmitter falls off, it may be damaged.
40  Operator’s Manual  ZM-540PA/541PAAttaching ElectrodesSelecting Electrode LeadCAUTIONOnly use Nihon Kohden specified electrodes and electrode leads. When other electrodes or electrode leads are used, the “CHECK ELECTRODES” message may appear and monitoring may stop.The following electrode leads can be used on the transmitter (option).BR-903PA, 3 electrodes, clip type BR-906PA, 6 electrodes, clip typeConnecting the Electrode Lead to the TransmitterConnect the electrode lead to the ECG/RESP socket on the transmitter.When transmitter is attached on an armCAUTIONDo not shake or swing the transmitter while holding the leads or cables connected to the transmitter. The transmitter may come off and injure someone or damage surrounding instruments.CAUTIONHold the connector of the electrode lead when connecting/disconnecting the electrode lead. If you disconnect the electrode lead by pulling the lead, it damages the electrode lead.
Operator’s Manual  ZM-540PA/541PA  41Electrode PositionFollow the physician’s instructions for electrode placement when available.For ECG monitoring, electrodes are attached only on the chest to allow patient movement and obtain continuous stable ECG. The following leads are examples. When also monitoring respiration, refer to the “Electrode Position for Respiration Monitoring” section.NOTEThe optimum electrode positions for ECG measurement are not always optimum for respiration measurement. Select positions that are suitable for both ECG and respiration measurement or positions which give priority to either ECG or respiration measurement.Electrode Positions for ECG MonitoringSix ElectrodesThe 6-electrode method with lead II and lead V5 is effective for monitoring myocardial ischemia.You can improve monitoring accuracy considerably by adding lead V4 to this combination.

Thoroughly dry the skin with a clean cotton pad.NOTE•  For a patient with frequent body movement, rub the sites with Skinpure skin preparation gel. However, do not use Skinpure skin preparation gel on sensitive skin.•  Do not place electrodes on a wound or on an inflamed, wrinkled or uneven skin surface.Attaching Electrodes to the PatientCAUTIONDo not reuse disposable parts and accessories.NOTE•  To maintain good contact between the electrode and skin, check that the paste of the NNNN
Operator’s Manual  ZM-540PA/541PA  45disposable electrode is not dry.•  When contact between the disposable electrode and skin becomes poor, replace electrodes with new ones immediately. Otherwise, contact impedance between the skin and the electrode increases and accurate ECG cannot be obtained.Refer to the electrode operator’s manual for details.1.  Carefully remove the backing paper from the electrode. Avoid touching the adhesive surface.2.  Place the electrode on the previously cleaned skin. Pay attention to the electrode lead color and symbol.3.  Clip the electrode lead to the electrode.4.  Fasten the electrode lead wire with surgical tape with an extra length of wire between the tape and the electrode. This lessens the movement of electrode leads by body movement and helps stable monitoring.Checking ECG on the Transmitter ScreenAfter attaching electrodes and connecting ECG leads, check that the electrodes are properly attached to the patient and the ECG waveform is acquired on the check electrodes screen.

58  Operator’s Manual  ZM-540PA/541PACAUTIONNIBP 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 flow 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.NOTE•  Measuring NIBP at a site other than the upper arm gives different values from those measured at the upper arm. When making diagnosis based on the NIBP values, measure NIBP on an upper arm.•  To accurately detect the pulsatile flow of the artery, the cuff should be wrapped around a bare upper arm.•  Do not use an abnormal cuff. The cuff deteriorates from use and cleaning. Before use, check the cuff and confirm that there is no flaw, crack or hole in it. Be careful not to damage the inflation bag. If the inflation bag has a hole or a flaw, it may burst during use. Dispose of an abnormal cuff and replace it with a new one.•  Refer to the NIBP cuff manual for details.Cuff PositionPlace the cuffed upper arm (brachium) at the same height as the patient’s heart. If the cuff is not at the same level as the heart, the weight of the blood affects the blood pressure reading. The pressure difference per unit height is 0.7 mmHg/cm. The blood pressure reading decreases when the arm is higher than the heart and increases when lower.The best measuring condition is when the patient is lying on his/her back with arms and legs relaxed. If the cuff position cannot be on the same level as the heart, the displayed blood pressure reading must be mathematically adjusted.When placing the transmitter on a bed, make sure that the hose is not bent.HeartWhen placing the transmitter on a bed, make sure that the hose is not bent.Heart

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.CAUTIONWhen performing NIBP measurement repeatedly, have a rest between measurements to recover adequate circulation.
82  Operator’s Manual  ZM-540PA/541PANOTE•  When measuring patients who are conscious, help the patient to relax. Measurement may not be accurate if the patient’s arm is tense or if the patient talks.•  The data for measurement on a leg tends to be higher than measurement on the arm. When making diagnosis based on the NIBP values, measure NIBP on an upper arm.•  Do not apply pressure to the cuff or air hose. NIBP may not be measured correctly because of noise or NIBP measurement may stop due to the NIBP safety circuit.•  When the transmitter is attached to the patient arm and the NIBP measurement is performed when moving, tell the patient to relax and keep quiet. Otherwise, measurement may be stopped or remeasurement is repeated due to body movement.•  If there is an abnormal noise generated during measurement, stop using the transmitter and contact your Nihon Kohden representative.•  Do not measure NIBP of a patient on whom an IABP is being used.

Electromagnetic propagation is affected by   absorption and reflection from structures, objects and people. *1  Field strengths from fixed transmitters, such as base stations for radio (cellular/cordless) telephones and land mobile radios, amateur radio, AM and FM radio broadcast and TV broadcast cannot be predicted theoretically with accuracy. To assess the electromagnetic environment due to fixed RF transmitters, an electromagnetic site survey should be considered. If the measured field strength in the location in which the ZM-540PA is used exceeds the applicable RF compliance level above, the ZM-540PA should be observed to verify normal operation. If abnormal performance is observed, additional measures may be necessary, such as re-orienting or relocating the ZM-540PA.*2  Over the frequency range 150 kHz to 80 MHz, field strengths should be less than 1 V/m for respiration and 3 V/m for all other functions.

Electromagnetic propagation is affected by   absorption and reflection from structures, objects and people. *1  Field strengths from fixed transmitters, such as base stations for radio (cellular/cordless) telephones and land mobile radios, amateur radio, AM and FM radio broadcast and TV broadcast cannot be predicted theoretically with accuracy. To assess the electromagnetic environment due to fixed RF transmitters, an electromagnetic site survey should be considered. If the measured field strength in the location in which the ZM-541PA is used exceeds the applicable RF compliance level above, the ZM-541PA should be observed to verify normal operation. If abnormal performance is observed, additional measures may be necessary, such as re-orienting or relocating the ZM-541PA.*2  Over the frequency range 150 kHz to 80 MHz, field strengths should be less than 1 V/m for respiration and 3 V/m for all other functions.
