NIBP Measurement Cycle
There are two different modes of measurement operation: manual and interval modes. The
manual mode requires the operator to initiate the measurement cycle.
The interval mode follows a configured plan of automatically initiated measurement cycles,
using the follow selections:
OFF (manual), STAT, or 1, 2, 3, 5, 10, 15, 20, 30, 60, 120, 240 minutes
NOTE:
When the NIBP STAT interval is selected, the Accutorr V
takes back to back (one right after the other) blood pressure
readings. As a safety precaution, there is a five minute or
10 measurement limit for continuous NIBP measurements.
After 5 minutes or 10 measurements, the NIBP module
automatically switches to the mode in use before NIBP STAT
was selected. This reduces the chance of surface vessel
rupture (petechia).
The maximum adult and pediatric measurement cycle is 180 seconds.
The maximum neonatal measurement cycle is 90 seconds.
The NIBP module adjusts the inflation pressure automatically according to the systolic
pressure of the last measurement. If the first measurement is unsuccessful, the subsequent
inflation pressures change to 50 mmHg higher than the previous systolic pressure in adult or
pediatric mode, and 40 mmHg higher than the previous systolic pressure in neonate mode.
(The subsequent inflation pressure should be greater than the systolic pressure in the previous
measurement).
2.3.1
Cuff Inflation Time
If the cuff pressure does not attain 15 mmHg within 20 seconds for adult and pediatric
patients, or 15 mmHg within 10 seconds for neonate patients from the start of inflation, the
Accutorr V retries measuring up to three times. If the target pressure is not reached after three
retries, the cuff is deflated, and a status code displays.
2.3.1.1
Cuff Pressure Automatic Check Algorithm
If the monitor cannot inflate the cuff to the Pressure Threshold within the expected time period,
the monitor deflates the cuff, cancels the measurement, shuts off the pump, and displays the
message “Unable to Measure”. The cancellation occurs based on the following tables.
