9 Technical description
Ventilator outlet bacteriological filter
Filtration
99.99999% bacterial retention at 0.3 µm
99.9999% viral retention at 0.02 µm
9.2.1.5 Oxygen sensor specifications
Lifespan Approximately 5000 h (variable time according to
concentration and temperature)
Conditions of storage and use Identical to those of the machine
Power supply Supplied by the ventilator, including when operat-
ing on internal battery
Calibration
Calibration is performed automatically during the
interactive tests.
Only frequent calibration (at least once a week)
will guarantee precision.
Minimum flow rate to guarantee precision 5 L/min
Drift of measuring precision over six hours < ±3 Vol.%
Response time at 90% (extreme conditions)
60 s (if volume > 300ml)
90 s (if volume between 50 and 300ml)
110 s (if volume < 50mL)
Response time at 90% according to ISO
80601-2-55 standard
< 12 s
Start-up time Immediate
Sampling rate of the O2 cell data 5 ms
Effect of humidity on oxygen measurements -0.03 (% per %RH at 25°C)
Effect of pressure
Compensation of the measurement according to
atmospheric pressure.
Compensation of measurement at average pres-
sure of respiratory cycle
Effect of ambient temperature
Compensation of the measurement according to
ambient temperature.
Note: Extreme temperatures damage the accura-
cy of the measurements.
