(1) When two tolerances are indicated, consider the higher value.
(2) For airway resistance greater than 150 cmH2O/L/s, the expired volume will have its tolerance changed to
10%. In this condition, the measured inspiratory volume remains unchanged.
Observations
•
In practice, the units of measure of pressure are equivalent, being able to adopt that 1 mbar =
1 hPa ≈ 1 cmH2O.
Specifications of Alarm and Safety System
•
Valve anti-asphyxia to protect against failures in gas supply.
•
Safety relief valve 100 cmH
2
O as basic standard ventilators in order to avoid overpressure in the
breathing circuit safety.
•
Active overpressure valve that does not detect obstructions, is activated to reduce the pressure
in the breathing circuit.
