42%

 

03B2
Describe the potential interactions of sevoflurane, desflurane and isoflurane with carbon dioxide absorbents.
60%

 

03B1
Draw and label, on the same X - Y axis, FA/FI curves for the following halothane concentrations in oxygen, showing a 30 minute period from starting administration.

a.                  Halothane 1%, subject breathing spontaneously.

b.                  Halothane 6%, subject breathing spontaneously.

c.                  Halothane 6%, subject paralysed and ventilated.

With reference to the major factors determining the shape of FA/FI curves explain the differences between (a) and (b), and (a) and (c).
