Cardiac changes with ageing vs obesity

In today's episode I cover the 'Past Saqs' from 'Applied Cardiac Physiology." The first SAQ looks at the consequence of tourniquet release after two hours (01:23) followed by the process's that cause oliguria in hypovolemic shock (09:45). Then I go through the model answers for CVS responses in severe blood loss (14:39), the effects of infusing Hartmann's solution (16:51) and briefly the impact of IPPV (21:52). Finally, the remaining SAQs look at the effects of a central neuraxial blockade (22:44), the effects of a pneumoperitoneum (27:01) and the effects of ageing and obesity (30:57). Good luck to all the viva sitters this week and thanks for listening! As always if you have any feedback let me know
