Let's do some Respiratory pathophysiology! Have you ever asked your patient to take a deep breath to increase their oxygen? We've all been there. I'm not pointing fingers. But here's the reality: There is a misconception that breathing deeply or rapidly increases the amount of oxygen in someone's blood. It doesn't. And here is why. Stop writing down an incorrect number just to avoid thinking about why your patient might actually be desaturating. It is an early warning tool. It is a sign.
