Operation Non-Invasive Blood Pressure Measurements (NIBP)
3.3.3.2 Suspension of NIBP Measurements
1. Press STOP to suspend an automatically timed measurement sequence or to end a
measurement cycle already in progress (deflate cuff).
2. Press START to take an immediate measurement and resume a suspended timed
measurement sequence.
NOTE: You can press STOP at any time to postpone a scheduled
measurement or to terminate a measurement cycle already
in progress.
CAUTION: Observe caution on all patients (Neonates, Pediatrics, and
Adults) when NIBP is set to the Continuous Mode and the 1
minute interval. When the NIBP “continuous” interval is
chosen, the Passport 2/Passport 2 LT will continually take
back to back blood pressure readings. As a safety
precaution, a limit is placed on continuous and 1 minute
interval measurements. In continuous mode, after 5
minutes, the NIBP interval will automatically switch to one
measurement taken every 5 minutes. In 1 minute mode,
after 10 minutes the NIBP interval automatically switches to
measurements taken once every 10 minutes. Reports have
been made of nerve injury occurring during use of
automatically cycled blood pressure cuffs. See the
Appendix, “Cautions when Using Automatically Cycled
Blood Pressure Cuffs”.
3.3.4 NIBP Pressure Limit Fail Safe
If the cuff is over-pressurized, the cuff will automatically vent to atmosphere and the NIBP
message window will alternately read “cuff over pressure” and “unable to measure”. Power
the system off and then on again.
3.3.5 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.
3.3.6 START and STOP Functions
The START and STOP functions have the following effects on the timed measurement
sequence (Interval or Timer Mode).
INTERVAL is set and you press START:
An unscheduled measurement is made. Taking this unscheduled measurement does not
affect the timing of the interval cycle, therefore, the scheduled measurements will be taken
as if there were no interruptions. Only one measurement is taken for each measurement
cycle - therefore, if the unscheduled measurement coincides with the scheduled
measurement, it counts as the scheduled measurement.
INTERVAL is set and you press STOP during the measurement:
The cuff deflates and interval measurements are suspended.
INTERVAL is set and you change the interval:
The measurement cycle is reset with the new interval. A measurement will be taken after
you press the START key.
