Causes: APO, asthma, infective COPD (consider ventillation)

Question 2

Define bradypnoea.

List 3 important causes.

Answer 2

RR

Question 3

What are the components that contribute to BP?

Answer 3

BP proportional to CO x TPR

Question 4

MAP most closely correlates to organ perfusion. MAP> 70 is normal, higher in HTN pts.

Question 5

What is malignant hyperthermia and how do you treat it?
