11.3 Data Input / Output
11.3.1 Analog Inputs
The ventilator provides up to 8 programmable channels for analog signal inputs. Each channel
shall be scalable for the input ranges specified.
Ranges: 0 to 1 VDC
0 to 5 VDC
0 to 10 VDC
Resolution: 0.25 mV (for 0 to 1 VDC)
1.37 mV (for 0 to 5 VDC)
2.5 mV (for 0 to 10 VDC)
11.3.2 Analog Outputs
The ventilator provides 4 signals at the analog output connector:
1. Airway Pressure, P
a
:
Range: -60 to 140 cmH
2
O
Scale: 1 cmH
2
O/25 mV
Accuracy: ± 50 mV or ± 5% of reading, whichever is greater
Zero Offset: 1.5 VDC at 0 cmH

O
2. Flow
Inspiratory/Expiratory:
When selected, the ventilator provides a continuous analog voltage representative of inspiratory
flow minus expiratory flow.
Range: -100 to 200 LPM(Adult)
Scale Factor: 1 LPM / 10 mV (Adult)
1 LPM / 25 mV (Pediatric)
1 LPM / 50 mV (Neonate)
Accuracy: ± 10% of reading or ± 30 mV, whichever is greater
Zero Offset: 3.0 VDC at 0 LPM
Machine:
When selected the ventilator provides a continuous analog voltage representative of machine
delivered flow.
Range: 0 to 200 LPM (Adult)
Scale Factor: 1 LPM / 25 mV (Adult)
1 LPM / 50 mV (Pediatric)
1 LPM / 100 mV (Neonate)
Accuracy: ± 10% of reading or ± 30 mV, whichever is greater
Zero Offset: None
