Automatic Adjustment in the Timer Mode
In the timer mode, the unit adjusts the inflation pressure according to the previous reading of
the systolic pressure. After the first measurement in the timer mode, the inflation pressure is
the previous sy50 mmHg in the Adult Mode and +30 mmHg in the pediatric and
neonate mode.
Suspension of Automatic NIBP Feature
To suspend an automatically timed measurement sequence or to end a measurement cycle
already in progress (deflate cuff):
1. Press DEFLATE (15).
To take an immediate measurement and resume a suspended timed measurement
sequence:
2.
Press START (13).
NOTE: Press DEFLATE (15) at any time to postpone a scheduled
measurement or to terminate a measurement cycle already
in progress.
CAUTION: Observe extreme caution on all patients (neonates,
pediatrics, and adults) when NIBP is set to the Continuous
Mode. A 5 minute limit is placed on continuous
measurements. After 5 minutes the unit will take a
measurement once every 5 minutes. Reports have been
made of nerve injury occurring during use of automatically
cycled blood pressure cuffs. See the Appendix, “Precautions
when Using Automatically Cycled Blood Pressure
Cuffs”.Observe extreme caution on all patients (neonates,

1.6.5.3 NIBP Pressure Limit Fail Safe
If the cuff pressure is over-pressurized, the cuff will automatically vent to atmosphere and the
NIBP message window reads CUFF OVERPRESSURE.
The unit must be turned off and back on again to reset the overpressure switch before any
new measurements are taken.
1.6.5.4 Cuff Inflation Time
If the cuff pressure does not attain 20 mmHg within 40 seconds of the start of inflation or if
the target pressure is not reached within another 60 seconds, then the cuff is vented and the
“RETRY” or “UNABLE TO MEASURE” message will display in the NIBP message window.
1.6.5.5 Start and Deflate Functions
The START and DEFLATE functions have the following effects on the timed measurement
sequence.
