1.3 Technical specifications
1.3.1 NIBP
Deflation rate, PR dep. 5...13 mmHg/s
Inflation time 20...185 mmHg, 1...5 s
Automatic software control, max. inflation pressure
adult 280
±
10 mmHg
child 200
±
10 mmHg
infant 150
±
10 mmHg
Over pressure limit, stops measurement after 2 seconds
adult 320 mmHg
child 220 mmHg
infant 165 mmHg
Safety valve limits the maximum cuff pressure to 320 mmHg in adult/child mode or 165 mmHg in
infant mode. Independent timing circuit limits pressurizing (>5 mmHg) time to 2 minutes 10
seconds maximum in adult/child mode, and 1 minute 5 seconds in infant mode.
Zeroing to ambient pressure is done automatically.
Inflation pressure is adjusted according to the previous systolic pressure, typically 40 mmHg
above. If the systolic pressure is not found, inflation pressure is increased typically 50 mmHg.
Max. measurement time
adult 2 min
child 2 min
infant 1 min
Pressure transducer accuracy is better than
±
3 mmHg or
±
2 % whichever is greater.
Max. error
±
4 mmHg.
