  1. I am a co2 retainer. Drs. tell me my levels are higher than any patient they have treated. I try to research my condition as much as possible but have never come across such a precise explanation as yours. Thank you so much. I use supplemental o2 but try to keep the flow as low as I can and still keep a decent saturation for fear of the whole hypoxic drive issue. I haven’t had an abg done in months. Last one was in the 90s. Is this normal for Drs. not to check my co2 levels more frequently? I worry about it.

  2. Required this knowledge for my exam, because of your explanation … I finally understand the hypoxia drive concept. Thank you so much.

  3. Even if you give them oxygen, it won't raise the oxygen levels at the sensors shown UNLESS THEY ARE BREATHING, if they stop breathing, oxygen levels drop regardless of how much supplemental o2 they are getting… theory here is nonsense

  4. Thank you so much, Dr. Campbell! Your explanation is so incredibly clear and concise 🙂 I love the way you pause and allow time for the viewers to answer your questions before you speak. This is a huge help with PA school, so again, I thank you! 😀

  5. does carbon dioxide only enter the lung alveoli during exhalation, or does some carbon dioxide also leave the body during inhalation? thanks in advance for your answer…
