 Caution
• NIBP measurement should be performed on the upper arm.
• During NIBP, 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 ¿ ngers to be inserted in between the cuff and the arm.
• The accuracy of a À ashing 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 an OMRON GS CUFF can be used with this monitor. The use of 
any other cuff may result in incorrect measurement.
