Causes and Types of Hypoxemia and Hypoxia

Today we look at 'Applied Respiratory Physiology!' This is another big topic and it's the culmination of all our other episodes. We start by discussing the fundamental basis for preoxygenation which is a must know LO (01:09). Then we assess how anaesthesia and different patient positions effect the respiratory system (07:18). I then go over what the effects of IPPV are and how PEEP is used to mitigate this (12:14). The next LO covered breaks down the changes that occur with ageing, morbid obesity, exercise and altitude on the respiratory system (17:20). The last LO for today switches focuses and here I outline the causes of hypoxemia and hypoxia (25:54). Now there are a lot of key SAQ's for this episode and that takes up a big chunk of this episode (31:19). This is the second last episode for respiratory physiology and we will finish with 'Respiratory Measurement.' Thanks for listening! As always if you have any feedback let me know!
