Making Manual Measurements
You can manually define the measurement interval of a patient's blood pressure.
To control manual operation
Initial Inflation Pressures and Reading Durations
The initial inflation pressure is the amount that the NIBP cuff will inflate for the first NIBP
When subsequent NIBP measurements are taken on the same patient (and if not in suspend
mode), the monitor adjusts the inflation value up or down based on the previous reading results.

Select the NIBP VS box. On the NIBP menu, toggle Auto Mode to
To begin automatic operation, press the NIBP Start/Stop key.
Select the Patient Type.
See Selecting the Patient Type on page 3‐11.
To start or stop the measurement, press the NIBP Start/Stop key.
Performing NIBP measurements too frequently can cause injury to the patient due to
blood flow interference.
Always monitor the NIBP cuff site (for example, by observation of the limb concerned)
to ensure that operation of the automated sphygmometer does not result in prolonged
impairment of the circulation of the blood of the patient.
Pressurization of the NIBP cuff can temporarily cause loss of function of
simultaneously used monitoring ME equipment on the same limb.
Adult is used for most adult patients: Initial inflation pressure: 165 ± 15 mmHg
Pediatric is used for any patient exhibiting low pulse amplitudes (a condition exhibited by
pediatric‐size patients): Initial inflation pressure: 130 ± 15 mmHg
Neo is used for most neonatal patients: Initial inflation pressure: 100 ± 15 mmHg
