Explanation:
Detailed explanation-1: -Cylinders-Oxygen is supplied at around 2000 psi (regulated to approximately 45 psi after it enters the machine). Oxygen flush is a “straight shot” from pipeline to common gas outlet (bypassing vaporizers and flowmeters), 35-75 L/min.
Detailed explanation-2: -The O2 flush valve bypasses the vaporizer and delivers oxygen gas only to the common gas outlet and then to the breathing circuit. Used to fill the breathing circuit with oxygen, it delivers a high but unmetered flow of oxygen. This flow, approximately 30 to 50 L/min, can quickly fill the breathing system.
