Flow Volume Loops

There is a feature on the display of you ICU ventilator or anesthetic machine that you likely pay little attention to - the flow volume loop. Indeed, you may ignore the flow-time waveform also. This is a pity - and you are missing out on tons of information about your patient. This tutorial commences with a description of the flow waveform (no previous knowledge required!) and the different waveforms that you are likely to encounter - sinusoidal, constant flow, decelerating flow and "shaved-off" decelerating flow (associated with pressure support). I then show you a series of flow volume loops and - yes you can pause the video and see if you can figure out what is going on with the patients.
