Welcome. My name is Divine. This is Episode 515 of the Divine Intervention Podcasts.

In today's podcast, we're going to be addressing a topic that I titled Ventiliter Physiology Part 2. Vintillator Physiology Part 2.

This is a continuation of episode 65 that deals with ventilator of physiology part one.

So into this podcast, we're going to be talking about some systems of ventilation

Many times you notice that those people, they feel very tired during the day.

And many times, you're going to notice that people that have

sleep apnea, um, at nights they'll have hypercarbia because they're holding on to CO2.

They're not able to blow off that CO2 very well at night. So they have hypercarbia.

Although usually during the day, they're completely fine.

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

then, and the person is obese, has the classic sleep apnea symptoms. So you notice that,

wow, this person seems to have hypercapnia during the day. the one thing you absolutely positively want to think about
