Tests
1. Details of the tests are included later in this chapter.
2. When authorized Philips Medical Systems personnel service the instru-
ment. The results are reported back to Philips. The collected data form a
database to be used in product development. It is not necessary for hospi-
tal personnel to report these results.
3. In the case of the NiBP Deflation Rate Test, applicable to the A3 only.

After 1 minute at approximately
250 mmHg, pressure drops no
more than 6 mmHg.
250 mmHg; ±5 mmHg
After 1 Minute at 250 mmHg,
pressure drops no more than
6 mmHg
Monitor Reports NiBP = 280
mmHg in <6 seconds
Overpressure Deflation is
activated at a value between
280 mmHg to 330 mmHg
Monitor reports NiBP >10
mmHg and <190 mmHg
