When Using Disposable Cuffs or YP-960T series Reusable Cuffs
To use these NIBP cuffs, an optional YN-990P extension hose (1.5 m) is required.
NOTE
Connect the joints properly. If there is an air leak, NIBP cannot be measured properly.
1. Connect the NIBP cuff to the extension hose.
2. Connect the other end of the extension hose
totheNIBPsocketonthetransmitter.Turn
thejointclockwiseuntilitclicks.
To disconnect the cuff from the transmitter,
turnthehosejointcounterclockwise.
Attaching the NIBP Cuff to the Patient
WARNING
Be 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.
CAUTION
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.
CAUTION
Do 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.
CAUTION
Do 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.
CAUTION
Do not reuse disposable parts and
accessories.
42 Operator’s Manual ZM-940PA/941PA
CAUTION
NIBP 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.
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 Position
Place 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.
Heart
When placing the transmitter on
a bed, make sure that the hose is
not bent.

the electrode lead by pulling the lead,
it damages the electrode lead.
Selecting the Electrode Position
Follow 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. Following leads are examples. When also monitoring respiration,
refer to the “Electrode Position for Respiration Monitoring” section.
NOTE
The optimum electrode positions for ECG measurement of a patient are not always
optimum for respiration measurement of the patient. Select positions suitable for both ECG
and respiration measurements, or positions which have priority for one measurement.

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 Patient
CAUTION
Do not reuse disposable parts and accessories.
NOTE
• To maintain good contact between the electrode and skin, check that the paste of the
disposable 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 the correct 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.

Electrode Position for Respiration Monitoring
Place the R/RA and F/LL electrodes so that the lungs are between the electrodes.
NOTE
The optimum electrode positions for ECG measurement of a patient are not always
optimum for respiration measurement of the patient. Select positions suitable for both ECG
and respiration measurements, or positions which have priority for one measurement.
Electrode Position Examples
NOTE
The following examples are when monitoring with 3 electrodes. ECG cannot be monitored
correctly when electrodes are attached as the following examples when monitoring with 6
electrodes.
Position 1
In this position, respiration measurement is available; however, there is a difference in amplitude
between different patients.
R or RA F or LL
Right infraclavicular fossa Fifth intercostal space on the
left midclavicular line, V4
Position 2
In this position, the waveform amplitude is usually large and the ECG lead is similar to Lead MII.
This position can be generally recommended.
R or RA F or LL
Right infraclavicular fossa Fifth intercostal space on the
left midaxillary line, V6
52 Operator’s Manual ZM-940PA/941PA

Attaching the Probe to the Patient
Attachtheprobetothepatientbyreferringtotheprobe’smanual.Makesurethatthelightemitter
and photo detector of the probe face each other at the attachment site.
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.
WARNING
Check 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.
58 Operator’s Manual ZM-940PA/941PA
CAUTION
If 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.
CAUTION
If 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.
CAUTION
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.
CAUTION
Do 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.
CAUTION
Do not use a probe which is
deteriorated by aging. Accurate
measurement cannot be performed.
CAUTION
Neonatal skin is delicate. Remove the
probe and tape carefully and slowly.
CAUTION
When removing a probe that is taped
to the skin, do not pull the probe cable
because this can damage the cable.
CAUTION
When removing the probe from the
attachment tape, do not pull the
sensor cable because this can
damage the cable.

Monitoring
When preparation is done, monitoring starts.
NIBP Oscillometric Method
NIBP is measured from the change in amplitude pattern of pulsatile oscillation in cuff pressure
as the cuff pressure is reduced from above systolic to below diastolic pressure. The occlusive-
oscillometry method uses this to determine the systolic, diastolic and mean arterial pressure.

Measuring NIBP
WARNING
Be 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.
WARNING
NIBP 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 CPR
WARNING
When 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.
CAUTION
When performing NIBP measurement
repeatedly, have a rest between
measurements to recover adequate
circulation.
62 Operator’s Manual ZM-940PA/941PA
NOTE
• 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. Measurement may
be incorrect due to the mixing of the patient’s own pulse and IABP pulse.
• NIBP cannot be measured on a neonate using this transmitter.

ECG and Respiration Monitoring
When the electrodes are attached and the ECG leads are connected to the electrodes, heart rate, ECG
waveform, respiration rate and respiration waveform appear on the monitor.
When 6 leads are used on this transmitter, up to 8 lead (I, II, III, aVR, aVL, aVF, Va and Vb) of
ECG waveforms can be displayed on the receiving monitor. 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.
Respiration is monitored by measuring changes in impedance between the RA and LL ECG
electrodes. This transmitter sends the changes in impedance to the monitor as a respiration
waveform. The monitor displays the respiration waveform and calculates respiration rate. Refer to
the operator’s manual of the monitor for details.

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 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.

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 the transmitter is used with an electrosurgical unit (ESU), firmly attach the
entire area of the ESU return plate. Otherwise, the current from the ESU flows into the
electrodes of the transmitter, causing electrical burn where the electrodes are
attached. For details, refer to the ESU manual.
CAUTION
Turn 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.
NOTE
• Noise generated from an electrosurgical unit may interfere on an ECG waveform, but will
not damage it.
• If an electric blanket is used and incorrect heart rate is displayed on the monitor, turn off
the pacing spike detection on the monitor.
• Turn the pacing spike detection to ON on the monitor when monitoring a pacemaker
66 Operator’s Manual ZM-940PA/941PA
patient. Pacing pulse is detected by the transmitter and transmitted to the monitor.
If the pacing spike detection is turned OFF, QRS and pacemaker spike may not be
distinguished and pacemaker failure may not be recognized.

SpO2 Monitoring
When monitoring starts, SpO2 and pulse waveform are sent to the monitor and SpO2, pulse rate and
pulse level bar graph are displayed on the transmitter LCD.
WARNING
SpO2 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
Check 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.
WARNING
When 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.
68 Operator’s Manual ZM-940PA/941PA
CAUTION
Turn 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 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.
CAUTION
Normal 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.
CAUTION
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.
CAUTION
When a message indicates a faulty
probe, stop monitoring and replace
the probe with a new one.
CAUTION
While a patient is on medication which
causes vasodilation, the pulse
waveform may change and in rare
cases the SpO2 value might not be
displayed.
NOTE
In order to maintain sufficient blood circulation, keep the measurement site warm by
covering it with a blanket or something similar. Warming the site is effective, especially for a
patient with a small pulse amplitude.
SpO2 and PR Display Order
You can select the display order for SpO2 and PR (pulse rate) on the LCD. Refer to the “Changing
Parameter Setup Settings” section.

NOTE
• When continuous SpO2 monitoring is necessary, attach the probe to the limb to which the
NIBP cuff is not attached and set “INHIBIT SpO2 DURING NIBP” on the PARAMETER
SETUP screen to OFF.
• When the probe is attached to the same limb as the NIBP cuff, set the sync source to a
parameter other than SpO2 on the receiving monitor.
• When monitoring SpO2 during STAT NIBP measurement, attach the probe to the limb to
which the NIBP cuff is not attached.

Recommended Separation Distances between Portable and Mobile RF
Communications Equipment
The ZM-941PA is intended for use in an electromagnetic environment in which radiated RF
disturbances are controlled. The customer or the user of the ZM-941PA can help prevent
electromagnetic interference by maintaining a minimum distance between portable and mobile RF
communications equipment (transmitters) and the ZM-941PA as recommended below, according to
the maximum output power of the communications.
