Oxygen pressure for ordinary bed: not less than 2bar (Article 4.2.2.1 of YY/T0187)

Oxygen pressure on ventilator and anesthesia machine: 4bar～4.5bar (Article 4.2.2.1 of YY/T0187)

Circulating working oxygen pressure: 4.8bar～5.0bar

Oxygen pressure for hyperbaric oxygen chamber : 7bar～10bar (Article 5.4.5 of GB12130-2005 "Medical hyperbaric chamber pressurized with air" stipulates that the oxygen source pressure is 4bar～7bar higher than the working chamber pressure, and Article 1 stipulates that the working chamber pressure shall not be higher than 3bar)

Note 1: The output pressure of the standard oxygen production system is between 3bar and 4.5bar; the standard oxygen cylinder pressure is 150bar.

Note 2: 1 kg pressure = 1bar = 0.1MPa = 1kgf/cm²
