In this episode, which was originally released in April of 2019 on From the Head of the Bed… a podcast for the anesthesia community, Ashley provides an incredibly detailed run down of the anesthesia machine: the flow of gas through the machine, high, intermediate and low pressure system components in the machine, variable bypass vaporizer structure & function, relevant gas laws, safety systems & features and more! If you’re an anesthesia learner just hitting the ORs, this show will give you a detailed run down on what you need to know to use the anesthesia machine. If you’re a seasoned provider and clinical educator/preceptor, this show provides a wonderful reminder of core information on the machine so you can best support your learners.

E – Cylinder Calculation
Amount of oxygen in cylinder in liters divided by liters of flow:
At full pressure (1900 PSI): 660 liters / 3 lpm = 220 minutes of O2.
At half pressure (950 PSI): 330 liters / 10 lpm = 33 minutes of O2.
