mmHg) for at least one full minute. If the readings are not equal for
at least one full minute, the NBP circuit requires calibration. See

NBP calibration
NOTE
Only perform this test if the NBP pressure test fails.
The overall accuracy of noninvasive blood pressure (NBP) readings by
the patient monitor depend on the following:
the zero pressure reading, and
the voltage span of the NBP sensor in the patient monitor.
This procedure provides a method of verifying these items are accurate
and also checks the NBP pneumatic circuit plumbing for leaks.
WARNING
When the NBP cuff is used in this procedure, it must be
tightly wrapped around a rigid cylinder or pipe. Do not
put the NBP cuff around a human arm during the
calibration procedures due to the potential for injury.
