Non-Invasive Blood Pressure (NIBP) measurement
Warning
Caution
If a cuff is used on some patients with an infection, treat the cuff as medical waste, or disinfect before
reuse. Otherwise, an infection may result.
If frequently performing NIBP measurement using a cuff over an extended period of time, periodically
check the patient’s circulation. In addition, wrap the cuff as indicated in the cautionary points in this
manual.
Do not connect the NIBP cuff or cuff joint to a luer lock adapter.
Do not bend cuff tube during inflation and deflation, particularly after a change of body position.
Do not wrap the cuff on the following parts:
- An upper arm on which intravenous drip or a blood transfusion is being performed.
- An upper arm on which an SpO2sensor, IBP catheter, or other instrument is attached.
- An upper arm with a shunt for hemodialysis
- An injured upper arm
If measuring blood pressure with the cuff wrapped on the arm on the side of the body where a
mastectomy was performed, check the patient’s condition.
NIBP measurement should be performed on the upper arm.
During NIBP measurement, stop excessive body movement by the patient and minimize trembling.
If a doctor has indicated that the patient has hemorrhagic diathesis or hypercoagulability, check the
condition of the arm after measurement.
Use the appropriate cuff size to ensure correct measurements. If too large a cuff is used, the
measured blood pressure value tends to be lower than the actual blood pressure. If too small a cuff is
used, the measured blood pressure value tends to be higher.
Before and during measurement, verify that none of the following apply to the patient:
- The part where the cuff is wrapped is at a different height than the heart.
(A difference of 10 cm (4 inches) in height may cause a variation in the blood pressure value of up
to 7 or 8 mmHg.)
- Body movement or conversing during measurement.
- Cuff wrapped over thick clothing.
- Pressure on the arm due to a rolled up sleeve.
In the case of a cuff for adults, the cuff should be wrapped to a tightness that allows two fingers to be
inserted in between the cuff and the arm.
The accuracy of a flashing measurement value that is out of the measurement range cannot be
guaranteed. Always check the patient’s condition before deciding what steps to take.
Do not use the cuff if it is damaged or has holes.
Only OMRON GS CUFF2 can be used with this device. The use of any other cuff may result in
incorrect measurement.

Note:
Setup
• Read and understand the manual for each optional accessory. This manual does not contain
cautionary information for optional accessories.
• Exercise caution with the cables and arrange so that the patient does not become entangled or
bound.
Before use / during use
• Check the following after turning on the power:
- No smoke, abnormal odor, or abnormal noise is emitted.
- Press each button and verify that it operates.
- For functions that cause icons to light or flash, verify that the icons light or flash (page 13).
- Measurement can be performed normally, and measurement error is within the tolerance value.
• If the screen is not displayed normally, do not use the unit.
• When recycling or disposing of parts (including batteries) of the unit, follow local government rules
and regulations.
Cleaning
• For cleaning, see page 24.
Rechargeable battery
• To prevent accidents, keep batteries out of reach of infants and small children.
• If you sense that something is wrong with a battery, immediately move it to a safe location and contact
the administrator responsible for the unit or your OMRON retail dealer or distributor.
• If the battery voltage is low, operation by battery may not be possible.
Non-Invasive Blood Pressure (NIBP) measurement
• If the patient has acute inflammation, a pyogenic ailment, or an external wound at the location where
the cuff is to be wrapped, follow the instructions of the doctor.
• Non-Invasive Blood Pressure measurement (NIBP) is performed by compressing the upper arm.
Some people may experience intense pain, or transient spotting caused by subcutaneous
hemorrhaging (bruising) may appear. The spotting will disappear with time; however, it may be
appropriate to inform patients for whom this may be a concern that spotting sometimes occurs, and if
necessary, refrain from measurement.
• Clinical evaluation of the unit was carried out in a resting position (feet on floor without crossing legs,
back supported by backrest, arm supported such that cuff is attached at same height as heart) in
accordance with ISO81060-2:2013. Measurement in a position other than the resting position may
result in differences in measurement results.
• As the patient's posture or physiological condition influences blood pressure, it easily fluctuates.
Recommend the followings to take a more accurate measurement:
- Make the patient relaxed.
- Do not talk to the patient.
- Let the patient rest for at least 5 minutes before the measurement.

Non-Invasive Blood Pressure (NIBP) Measurement
Non-Invasive Pressure Measurement Principles
Oscillometric method
The beat in the pulsation generated by the contraction of the heart is captured as the pressure inside
the cuff to measure the blood pressure. If the cuff wrapped around the upper arm is pressurized
sufficiently, the blood flow stops, but the beat of the pulsation is present and the pressure inside the cuff
receives this and oscillates. Next, as the pressure inside the cuff gradually decreases, the oscillation of
the pressure within the cuff gradually increases and reaches a peak. As the pressure within the cuff
decreases further, the oscillation decreases from its peak.
The pressure within the cuff and the relationship with the increase and decrease of the oscillation within
the cuff in this series of processes are stored into memory, calculations are carried out, and the blood
pressure value is determined.
The oscillometric method does not determine the blood pressure value instantly like a microphone type
automatic blood pressure gauge with the auscultation method, but rather determines it from the series
of change curves as explained above. Therefore, it is not easily affected by external noise, an electric
scalpel or other electro surgical instruments.
