Video Tip: Capnography for Deeper Sedation | January 2022-Capnography for Deeper Sedation

Video Transcription

For those of you who aren't really familiar with capnography for sedation monitoring, this is a tracing that shows what might happen if you have somebody retaining CO2.  And if you go ahead and advance the next slide, we'll see sort of a couple of other curves over here.  The normal sort of capnography in somebody who's breathing normally on the left, and then down below on the dotted line, sort of a slanted dotted line shows you what somebody  who is an asthmatic, who has a prolonged expiratory phase may look like. And then go ahead and advance next.  And this is one that is a patient who's losing their perfusion, and therefore their measure of ventilation and is going into cardiac arrest and what may happen to the curve.  So there are earlier indicators before hypoxemia that hypoxemia will soon occur or worse potentially may occur by using capnography.

Video Summary

The video discusses capnography for sedation monitoring, showing various tracings to illustrate different scenarios. The first tracing demonstrates what happens when someone retains carbon dioxide (CO2). The next tracing portrays the normal capnography of a person breathing normally, while the third tracing shows an asthmatic individual with a prolonged expiratory phase. Finally, the video demonstrates how capnography can indicate a patient losing perfusion and progressing into cardiac arrest. Through capnography, earlier indicators of hypoxemia can be detected, providing warning signs before it worsens. No credits were mentioned in the transcript.
