1. ECG MONITORING

General

1
To monitor ECG, attach disposable electrodes to the patient and connect
them to the ECG/RESP socket on the input unit or BSM-1700 series bedside
monitor. Up to 12 leads can be monitored with arrhythmia analysis and ST level
measurement.
WARNING
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. In this case, set the <IMPEDANCE MEASUREMENT>
on the RESP/CO2 window to OFF on the bedside monitor. For a
patient that requires the respiration monitoring, measure the
respiration by thermistor method.
NOTE
• ECG monitoring using 10 electrodes is not available when an AY-660P
input unit is used.
• When a line isolation monitor is used, noise from the line isolation
monitor may resemble actual ECG waveforms on the bedside monitor
and cause false heart rate alarms or no alarm at all.
User’s Guide Part II BSM-6000 1.3
1. ECG MONITORING

Using the Output Signal from the ECG/BP OUT Socket

CAUTION
When using the output signal from the monitor as
the synchronization signal for other equipment
such as an IABP (intra-aortic balloon pump) or
defibrillator:
• Set the timing of the IABP by checking the
waveform on the IABP screen.
• Check the condition of the bedside monitor
at all times. The output signal may become
unstable.
• Check that the delay time of the output signal is
within the range of the connected equipment.
• Analog ECG, analog BP and heart rate trigger output are not available
when an AY-660P input unit is used.
• The output signal from the ECG/BP OUT socket may become unstable
in the following conditions.
- Electrode is dry or detached.
- Electrode lead is damaged or disconnected from the electrode.
- Electrode lead is pulled.
- AC interference or EMG noise superimposed.
- Air bubbles or blood clog in the circuit for monitoring IBP.
- Cord or cable is disconnected or damaged.
• All instruments which are to be connected to the ECG/BP OUTPUT
socket must use a YJ-910P or YJ-920P ECG/BP output cable and
comply with the IEC 60601-1 safety standard for medical equipment.
CAUTION
Only a Nihon Kohden defibrillator can use the
output signal from the monitor as a
synchronization signal. Check that the delay time
of the output signal (heart rate trigger 20 ms
maximum) is within the range of the connected
defibrillator.
NOTE
The following shows the delay time of the output signal.
Output Signal Delay Time
ECG 20 ms
BP 40 ms

The 5-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. Ca and Cb (Va and Vb) can be at any
position of the standard 12 leads C1 to C6 (V1 to V6), but C4 and C5 (V4 and
V5) are most appropriate for myocardial ischemic monitoring.
For details on attaching the Ca or Cb electrode to C1, C2, C3 or C6, refer to the

Mason-Likar Modification
WARNING
Do not use 12 lead ECG interpretation results and measured values
from the Mason-Likar modification for diagnosis because the limb
electrode placement is not the same as the standard 12 lead ECG.
This may cause wrong diagnosis since 12 lead ECG interpretation of
this monitor is based on the standard 12 lead ECG.
The Mason-Likar modication places the four limb electrodes close to the
shoulders and lower abdomen. The six C (V) electrodes are placed on the chest
in the same position as the standard 12 lead ECG electrode placement. The
waveforms acquired from the Mason-Likar modication are different from those
of the standard 12 lead.

Selecting Electrodes and Lead

Select the appropriate electrodes and lead according to the purpose.
WARNING
When using a defibrillator together with the
monitor, use Ag/AgCl electrodes. Other types of
electrodes, stainless steel in particular, will
adversely affect the ECG waveform by slowing
the baseline recovery on the monitor and result in
no monitoring immediately following defibrillation.
CAUTION
Only 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
ECG monitoring may stop.
CAUTION
• When using the electrodes with DIN type lead,
use only Vitrode V or N electrodes. If other
electrodes are used, the electrode lead might
not be properly connected and ECG monitoring
may be unstable.
• Do not use electrodes of different metals. ECG
monitoring may be unstable if electrodes of
different metals are used.
NOTE
• Electrode leads other than Nihon Kohden’s might not be defibrillator-
proof.
• Do not use different types of electrodes together. This might cause ECG
monitoring to become unstable.

WARNING
After attaching the electrode to the patient and connecting the cable
to the monitor, check that electrodes are attached to the patient and
check that the cable is connected to the monitor properly. When the
electrodes are removed from the patient, do not touch the metal part
of the electrode with bare hands or let the metal part of the electrode
contact the metal part of the bed or any other conductive parts.
Failure to follow this warning may cause electrical shock or injury to
the patient by discharged energy.
CAUTION
Do not reuse disposable electrodes.
NOTE
• To maintain good contact between the electrode and skin, check that
the paste of the disposable electrode is not dry.
• When contact of the disposable electrode becomes poor, replace the
electrode with a new one immediately. Otherwise, contact impedance
between the skin and electrode increases and the correct ECG cannot
be obtained.
To obtain a stable ECG:
• Shave excess hair.
• Rub the patient’s skin with a piece of cotton where the electrodes are to be
attached.
• If the skin is dirty, clean with soap and water. Dry completely.

Measuring ST Level

1
The ST level is the amplitude between the baseline and ST wave. The ECG
waveform is averaged for 15 seconds to remove artifacts. The baseline and the
ST wave are detected from the averaged ECG, and the ST level is measured.
NOTE
• If there are too many arrhythmias, there is noise on the ECG, or the
heart rate is below 32, ST level might not be measured and ST level is
not displayed on the screen.
• Although the ST algorithm has been tested for accuracy of the ST
analysis result, the significance of the ST level changes need to be
determined only by a physician.
• If there is baseline drift on the ECG, ST waves are distorted and the ST
measurement may be impossible.
ST levels of up to 12 leads can be displayed on the ST window of the Review
window. Refer to “ST Window” of the Operator’s Manual or Section 6 of the
User’s Guide Part I.
You can change the ISO point, J point and ST point for ST level measurement
on the ECG window → ST POINT page. Refer to the “Changing the ST Level
Measurement Condition” section.

Detached Electrode Detection and Display

When an electrode or electrode lead is detached during ECG monitoring, a
“CHECK ELECTRODES” alarm occurs.
When monitoring with 6 or 10 electrodes and <AUTO LEAD CHANGE> on
the ECG window is set to ON, and the “CHECK ELECTRODES” message is
displayed for more than 5 seconds, the lead for the rst trace on the home screen
is automatically changed to a stable lead.
Five seconds after the detached electrode or electrode lead is attached again, the
lead of the rst trace returns to the lead prior to auto lead change.
While the “CHECK ELECTRODES” message is displayed, the correct ECG
waveform is not displayed. To prevent incorrect reading of ECG during an
error condition, the ECG waveform is temporarily replaced with a square wave
and at line. Check the electrodes if this message appears. Refer to “Screen
Messages” section of the Operator’s Manual.
When the “CHECK ELECTRODES” message is displayed, ECG is
not monitored properly and the ECG alarm does not function. Check
the electrode, electrode leads and connection cord, and if necessary,
replace with new ones.

Monitoring Arrhythmia

General

1
The following functions are available for arrhythmia monitoring.
• Arrhythmia alarm indication (alarm sound, screen message and alarm indicator
lamp). Refer to the Operator’s Manual or Section 5 of the User’s Guide Part I.
• Arrhythmia waveform storage (Arrhythmia recall les). Refer to the
Operator’s Manual or Section 6 of the User’s Guide Part I.
• Arrhythmia waveform recording. Refer to the Operator’s Manual or Section 10
of the User’s Guide Part I.
• VPC display and trendgraph. Refer to the Operator’s Manual or Section 4 and
6 of the User’s Guide Part I.
WARNING
For arrhythmia monitoring, set <ARRHYTHMIA ANALYSIS> on the
ECG window to ON. Otherwise, there is no sound or indication for
arrhythmia alarms (except for ASYSTOLE).
When arrhythmia analysis is set to on, arrhythmia analysis starts as soon as
the ECG monitoring starts. The monitor automatically detects and classies
arrhythmia by comparing each beat of the real-time ECG waveform to a
reference ECG waveform (dominant QRS). If the following points of a QRS do
not match the dominant QRS, that QRS is recognized as an arrhythmia.
• RR interval
• QRS width
• QRS amplitude
• QRS polarity
It is important to check the dominant QRS on the ECG window at the start of
ECG monitoring for accurate arrhythmia monitoring.
CAUTION
At the start of ECG monitoring, check that the dominant QRS is
appropriate. Otherwise arrhythmia monitoring may be inaccurate.
When the QRS wave or RR interval changes too frequently, it becomes difcult
for the monitor to distinguish between the normal ECG and arrhythmia. To solve
this problem, the monitor uses pattern matching and multi template matching for
analyzing arrhythmia. However, when the patient’s QRS changes rapidly, check
that the appropriate dominant QRS is used for arrhythmia analysis.

1. ECG MONITORING
Learning the ECG Waveform for Arrhythmia Detection (VPC
Learning)
The monitor automatically detects and classies arrhythmia waveforms when
arrhythmia analysis is set to on. To do this, the monitor compares each beat of
the real-time ECG waveform to a reference ECG waveform which is called
dominant QRS.
The monitor automatically samples this dominant QRS in the following
situations:
• When ECG monitoring begins
• When the monitoring lead is changed
• When the “CHECK ELECTRODES” alarm message is resolved
• When the waveform changes from ventricular rhythm to supraventricular
rhythm and satises the conditions specied by Nihon Kohden.
Sampling the reference waveform is called “Learning”.
Learning takes a few seconds. During learning, a “LEARNING” message is
displayed on the screen. After learning, the dominant QRS is replaced with the
new one and the monitor resumes analyzing the ECG waveforms.
NOTE
• To make the monitor learn, <ARRHYTHMIA ANALYSIS> on the
ARRHYTH ANALYSIS page of the ECG window must be set to ON.
• During learning, alarms other than “ASYSTOLE”, “VF”,
“BRADYCARDIA” and “TACHYCARDIA” do not function.
You can make the monitor “relearn” the reference ECG waveform at any time,
for example, when the automatic VPC classication is questionable.
CAUTION
If there is any doubt about the arrhythmia analysis, make the monitor
relearn the patient’s ECG and check that the dominant QRS is
appropriate. Otherwise, an important arrhythmia may be overlooked.

1. ECG MONITORING

Turning ECG Measurement On or Off

When monitoring SpO2 only, detection of arrhythmia and asystole is
not available and arrhythmia alarms such as ASYSTOLE, VF or VT
are not available. If the patient requires ECG monitoring, monitor the
ECG.
When monitoring SpO2 only (without ECG monitoring), turn on both
the upper and lower limit alarms for PR and SpO2. If the patient’s
pulse is not detected during asystole or other condition, a “CANNOT
DETECT PULSE” or “CHECK PROBE” alarm occurs instead of an
SpO2 limit alarm. Furthermore, if the patient has no pulse, noise from
probe movement could be misjudged as a pulse and cause an
incorrect PR or SpO2 value to be displayed.

Optimum Lead
NOTE
Follow the physician’s instructions for lead position when available.
It is generally considered that Lead II and Lead V1 are suitable for arrhythmia
monitoring and that Lead V4 and Lead V5 are suitable for myocardial ischemia
monitoring.
Some types of ECGs are difcult for automatic analysis, and heart rate or
arrhythmia detection level is not accurate for some patients. In these cases, use
the following procedure to nd the appropriate lead for automatic analysis.
1. Measure the patient’s ECG with the standard 12 ECG leads using an ECG
instrument.
2. Select the optimum lead according to the following guidelines:
i) Select the lead with the highest QRS wave amplitude and least
difference in amplitude compared with a VPC or pacing pulse.
0.5 ≤ QRS1/QRS2 ≤ 2
ii) Select the lead with less than 0.2 mV amplitude of the P-wave.
P ≤ 0.2 mV

Use with an Electrosurgical Unit

For use with an electrosurgical unit (ESU), this monitor has a circuit to
protect the patient from skin burn and to reduce ESU interference on the ECG
waveform. However, the effectiveness of this circuit depends on electrode
position and monitor setup. With an ESU, pay attention to the following points.
When the monitor 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 monitor, causing
electrical burn where the electrodes are attached. For details, refer to
the ESU manual.
When using the monitor with an ESU, locate the monitor and ESU
appropriately and ground instruments properly. Otherwise noise from
the ESU may interfere with the ECG and the heart rate and
arrhythmia analysis may be incorrect.

2. RESPIRATION MONITORING

General

Measurement Method

On this monitor, respiration can be measured by two methods: impedance
method and thermistor method. When respiration is measured by both the
impedance method and thermistor method, the values measured by the thermistor
method is used.
Impedance Method
In the impedance method, respiration is measured and monitored by attaching
the ECG electrodes to the patient and connecting them to the ECG/RESP socket.
This method measures changes in impedance between the R and F (RA and LL)
or R and L (RA and LA) ECG electrodes.
WARNING
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. In this case, set the <IMPEDANCE MEASUREMENT>
on the RESP/CO2 window to OFF on the bedside monitor. For
a patient that requires the respiration monitoring, measure the
respiration by thermistor method.
Thermistor Method
In the thermistor method, respiration is measured and monitored by attaching the
respiration pickup to the patient or connecting it to the respiration circuit, and
connecting the respiration pickup to the MULTI socket.
This method measures and compares temperature changes caused by respiration
and inspiration using the respiration pickup.
Use this method when using an ESU or if measurement by the impedance
method is unavailable.
NOTE
The MULTI socket on the AY-660P input unit cannot be used for
monitoring respiration in thermistor method.

Electrode Position and Waveform Examples

Respiration can be measured by the impedance method when the R (RA) and F
(LL) or R (RA) and L (LA) electrodes are placed so that the lungs are between
the electrodes.
The optimum electrode positions for ECG monitoring of a patient are not always
optimum for respiration monitoring of the patient. Select the optimum positions
for both ECG and respiration measurements or measure respiration by the
thermistor method.
The amplitude of the respiration waveform differs according to the electrode
position. The following shows different examples of respiration waveforms

2. RESPIRATION MONITORING

Monitoring Respiration

When preparation is done properly, the respiration waveform appears on the
screen.
NOTE
Increase in the temperature of the inspired air during monitoring in
thermistor method causes decrease in the temperature difference
between inspiration and expiration, and the amplitude of the respiration
waveform becomes small. When the inspiration temperature increases
higher than the expiration temperature, the phases of expiration and
inspiration may be reversed.
In impedance method, the respiration data do not appear on the screen when
respiration monitoring in impedance method is set to OFF (the “RESP OFF”
message appears). When using an ESU, noise is superimposed on the waveform
and the respiration measurement cannot be monitored accurately. When
respiration monitoring is necessary, use the thermistor method or monitor CO2.
NOTE
• The respiration rate can only be detected from one parameter. When
, respiration and anesthetic gas are monitored at the same time, the
CO
2
respiration rate is detected in the following priority.
Gas > FLOW > CO2 > thermistor respiration > impedance respiration
• When ON is selected at <DISPLAY IMP-RR AS SECOND
PARAMETER> on the OTHER page of the RESP/CO2 window,
the respiration rate is detected from two parameters. Refer to the

General

On this monitor, CO2 can be measured by either mainstream method or
sidestream method.
To monitor CO2 by the mainstream method, connect the TG-900P, TG-920P,
TG-950P, TG-970P or TG-980P CO2 sensor kit to the patient’s respiration circuit
or directly to the patient and connect the CO2 sensor kit to the MULTI socket or
PRESS CO2 socket.
NOTE
The TG-950P CO2 sensor kit is not available for BSM-6000A series.
To monitor CO2 by the sidestream method, the optional AG-400R CO2 unit,
Oridion portable bedside monitor Microcap® or Covidien Microstream
®
Micropod™ capnography module is required.

Mainstream Method

To use the AG-400R CO2 unit, the QF-905P interface is required. For details on
the sidestream method, refer to the AG-400R CO2 unit operator’s manual.
To connect the Microcap® monitor, the QF-921P interface is required. Microcap
is a registered trademark of Oridion Medical Ltd.
To connect the Micropod™ capnography module, the QF-801P interface is

In the mainstream method, the sensor is located directly in the respiration circuit.
There are two types of sensors for different calculation methods.
Semi-quantitative method using the TG-900P or TG-920P CO2 sensor kit
Measurements are based on the assumption of no CO2 gas in the inspiration.
The CO2 concentration in the respiration is calculated by taking the CO2
concentration in the inspiration as 0 mmHg (0 kPa).
Quantitative method using the TG-950P, TG-970P or TG-980P CO2 sensor
kit
The CO2 partial pressure in both inspiration and expiration is measured.

• No delay in the measurement time.
• Measurement is stable over a long period of time.
• Few measurement troubles due to mixture of water droplets.
Limits
• TG-900P, TG-950P, TG-970P or TG-980P CO2 sensor kit cannot be used on
non-intubated patients.
• Due to the weight of the TG-900P, TG-950P, TG-970P or TG-980P CO2 sensor
kit, load is easily imposed on the tracheal tube.
• The dead space volume is relatively large.
A small portion of the breath is continuously sampled from the respiratory circuit
or directly from the patient’s nostril. CO2 molecules in the breath sample absorb
infrared light at 4.3 µm. The absorption is proportional to the concentration
of the CO2 and the concentration can be determined by comparing the level of
absorption to that of a known standard.

The sidestream CO2 measurement method has the following merits and limits
compared to the mainstream method. Understand these points when performing
measurements.
NOTE
• The AG-400R CO2 unit is not available for BSM-6000A series.
• Oridion Microcap® portable bedside monitor is not available for
BSM-6000K series.
Merits
• CO2 sensor adapter can be used on non-intubated patients.
• Lightweight adapter reduces risk of extubations.
Limits
• Delay in the measurement time.
• Sometimes CO2 waveform is distorted.
• Longtermmeasurementisdifcultduetomixtureofwaterdropletsand
secretions in the tube.

Measurement Error with the TG-900P or TG-920P CO2 Sensor Kit

With the TG-900P or TG-920P CO2 sensor kit, measurements are based on the
assumption that the inspiration contains no CO2 gas. If CO2 gas mixes in the
inspiration, measured values will be lower than normal.

CAUTION
Supply adequate oxygen when measuring CO2 partial pressure of
a patient connected to a Jackson Rees, Mapleson D or any other
respiration circuit where CO2 gas may be present during inspiration.
The semi-quantitative method measures CO2 partial pressure based
on the assumption of no CO2 gas in the inspired air; it assumes
CO2 partial pressure 0 mmHg (0 kPa) in the inspiration of every
respiration. If the inspired air contains CO2 gas, the measured CO2
value may be lower than the actual value.
CAUTION
When measuring CO2 partial pressure of a patient with an oxygen
mask, set the oxygen supply to 5 L/min or more. If CO2 gas remains
in the oxygen mask and mixes with the inspired air, the measured
value may be lower than the actual value.

The TG-900P and TG-920P CO2 sensor kits do not adjust the
measurement value to compensate for different atmospheric
pressure. Be careful when reading the value when using the CO2
sensor kit at high altitudes because the measurement value may be
inaccurate.
The measurement value drops 0.13 kPa (1 mmHg) for 5.33 kPa (40 mmHg) CO2
gas when an atmospheric pressure drops 3.3 kPa.

WARNING
When using the airway adapter or nasal adapter
on a patient with low ventilatory volume, the
CO2 may mix in the inspiration due to the airway
adapter’s dead space, resulting in inaccurate
measured values or difficulty in detecting apnea.
Perform ventilation taking into consideration the
dead space of the adapters.
CAUTION
The CO2 data may be inaccurate when
monitoring a patient with an extremely high
respiration rate or irregular respiration. Read the
measured values carefully.
CAUTION
When using an anesthetic instrument with a
volatile anesthetic agent, the CO2 measurement
may be inaccurate.
CAUTION
When monitoring CO2, make sure that the
gas composition is entered. Otherwise the
measurement result may be inaccurate.
CAUTION
Select the airway adapter or nasal adapter
taking into consideration the patient weight and
ventilation volume. If an inappropriate airway
adapter or nasal adapter is used, the resistance
in the respiration circuit increases and it causes
incorrect measurement value.
