The physiology teacher i needed in first year of medschool. Thank you!

Thank you so much for this explanation ❤❤

That you for your awesome videos :)

URGENT QUESTION : In your video, you mention that when taking into account both the diffusion capacity and partial pressure gradient of O2 and CO2, these gases diffuse the alveolar capillary membrane at the same rate. Nevertheless, a type 1 respiratory failure (e.g. pulmonary edema) is characterised by low pO2 levels and normale to low pCO2 levels. If both these statement are correct, how can a type 1 respiratory failure (e.g. pulmonary edema) only negatively affect pO2 levels if both O2 and CO2 diffuse the alveolar capillary membrane at the same rate?
