Related Pressure of Medical Emergency Ventilator

Gas pressure and airway pressure of emergency ventilator:

1. Gas pressure: the gas pressure output by the oxygen cylinder through the pressure reducing valve (or central oxygen supply pipeline), which is high pressure, and the range required by the industry standard is 0.28-0.6MPa.

2. Airway pressure: the pressure in the breathing circuits connecting the patient, which is low pressure, and the common range is 5-60 HPa.

3. Conversion of common pressure units:

0.1 MPa = 1 kgf/cm2 = 1 bar = 100 kPa

1 MPa = 145 PSI

1 kPa = 10 HPa = 1000 Pa

1 mm water column = 0.098 HPa

1 mm Hg = 1.3 HPa
