1.3 Technical specifications
1.3.1 NIBP
Deflation rate, PR dep. 3 to 8 mmHg/s
Inflation time 20 to 185 mmHg, 1 to 5 s
Automatic software control, max. inflation pressure
adult
280
±
10 mmHg
child 200
±
10 mmHg
infant 145
±
5 mmHg
Over pressure limit, stops measurement after 2 seconds
adult
320 mmHg
child 220 mmHg
infant 160 mmHg
The safety circuit limits the maximum cuff pressure to 320 mmHg in adult/child mode or 160
mmHg in infant mode. Independent timing circuit limits pressurizing (>15 mmHg) time to 3 minutes
maximum in adult/child mode, and 90 seconds at (>5mmHg ) 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 120 s
child 120 s
infant 75 s
Pressure transducer accuracy is better than
±
3 mmHg or
±
2 % whichever is greater.
Max. error
±
4 mmHg.
