Today I cover the topic ‘Applied Cardiac Physiology.” This is the biggest topic so far in our cardiology series and I had to divide it into 2 parts. Today I look at the LO’s starting first with the CVS effects of pneumoperitoneum (01:19) and the effects that occur with changes in patient position (06:13). Then I discuss the cardiovascular responses to exercise (12:45), Valsalva (16:58) and positive pressure ventilation (22:30). Then we go into depth examining the changes that occur with ageing (28:42) and obesity (32:35). The final LO for today is multiple LO’s in one and a very deep dive looking into all aspects of shock (37:13). In Part 2 of this topic, I will go through the SAQs.  Thanks for listening! As always if you have any feedback let me know
