Welcome. My name is Devine. This is episode 515 of the Devine Intervention

Podcasts. Into this podcast we're going to be addressing our topic that I title

ventiliter Physiology Part 2.

Ventiliter Physiology Part 2.

This is a continuation of episode 65

that deals with ventilator physiology part 1.

So in today's podcast, we're going to be talking about some systems of ventilation

that I think will be helpful to you for your USMLE exams, and not just for your SMLE exams, but just for general understanding of

ventilators. Although, please again, remember, these podcasts are solely for educational

purposes, they are not for medical decision-making or anything like that.

So let's jump right into it. So what if they give you a question about a 31-year-old male and you're told that his BMI is 32 and that he has been queried multiple times at his place of work

because he has been found to be falling asleep. If you think about that, what should you think?

I really hope you're saying, oh divine, this sounds an awful lot like obstructive sleep apnea.

You're going to see that in a person that is obese, the person snores, the person has a short thick neck sometimes. Many times you notice that those, they feel very tired during the day and many times you're going to notice that people that have sleep apnea, at night they'll have hypercaria because they're holding onto CO2.

They're not able to blow off that CO2 very well at night, so they have hypercaria.

Although usually during the day they are completely fine.

Although if you notice that a person has like deep time hypercarbia, deep time hypercapnea,

then and the person is obese has the classic sleep apnea symptoms where you notice that while this person seems to have hypercapnea during the day, the one thing you absolutely positively want to think about is the person

potentially having something I like to call obesity hyperventilation

syndrome obesity hypovintillation syndrome and remember the person sleep apnea, you're obviously going to diagnosis with a sleep study.

You're going to perform polysomography and then you're going to treat it with C-pop orPAP. You can also recommend lifestyle modifications like lose weeks and things like that.

So let's kind of talk about this whole C-PAP business. I think that's something that's kind of important to understand.
