What is oxygen failure shut off valve?

The oxygen fail-safe valve ( " A " ) is designed so that the nitrous oxide supply will be turned off automatically when oxygen delivery is compromised or depleted before the nitrous oxide tank is empty. N 2 O: Nitrous oxide.

How does an oxygen failure alarm work?

The oxygen supply pressure failure alarm sounds an audible alarm in case of oxygen supply pressure loss. Usually this feature is combined with the low oxygen pressure cutoff feature, so that the alarm sounds and the flow of gases stop at about the same tune.

What is the lowest level of O2 flow at which the fail-safe mechanism of a sedation unit will stop the flow of N2O O2 sedation?

Its fail-safe component shuts off nitrous oxide if the oxygen flow is less than 200 mL/min, or if the oxygen fresh gas valve is closed.

What is the purpose of oxygen flush valve?

The oxygen flush valve is a device to allow direct communication between the oxygen high-pressure circuit and the low-pressure circuit. When the oxygen flush button is depressed, the oxygen flush valve will open and deliver 100% oxygen flow of 35 to 75 L/min to the breathing circuit and mainly provide jet ventilation.
