Manual NIBP Measurements and General NIBP Measurement Information
If an error code displays in the Systolic Display or a status code in the Room/Bed Display,
refer to Section 3.16, Status and Error Codes, for its explanation. A successful measurement
clears a status code. To clear a status code, press the
ROOM/BED NUMBER
key (24).
6.
When required, press the
DEFLATE
key (36) to interrupt a measurement. The cuff will
deflate.
NOTE:
Once the initial measurement is taken for a room/bed, the
Accutorr Plus will continue to use the selected patient size.
NOTE:
Check the patient’s limb for any indications of circulation
impairment.
3.3.1
NIBP Pressure Limit Fail Safe
If the cuff is over-pressurized, it will automatically deflate and the status code 8812 (STOP -
CUFF OVER PRESSURE) or error code 987 (STOP - HARDWARE OVER PRESSURE) will be
displayed in the Room/Bed or systolic display.
The unit must be turned off and back on again to reset the hardware over-pressure switch
(error code 987) before any new measurements can be taken.
3.3.2
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 deflated and
status codes will be displayed in the Room/Bed display. See section 3.16 for a list of error
and status codes.
3.3.3
Automatic Adjustment of Cuff Inflation Pressure (Adaptive
Inflation)
The unit adjusts the inflation pressure according to the previous reading of the systolic
pressure. After the first successful measurement, the inflation pressure is the previous systolic
+50 mmHg in the adult mode, +50 mmHg in the pediatric mode and +40 mmHg in the
neonate mode. When not in Interval mode the Adaptive inflation may be disabled.
To view the current inflation pressure, press and hold (2 beep tones, approximately 3
seconds) the Patient Setup Key (37). The current inflation pressure is shown in the MAP
display. If required, use the Patient Info. Up & Down arrow keys (27 & 28) to change the
inflation pressure. It is also possible to permanently override this adjustment in the User
Configuration. See section 3.15 for details.
