Answer 5

CO

Question 6

What are some sources of CO?

Answer 6

Question 7

Does our susceptibility to CO poisoning increases with altitude because of the lower levels of pp02 available in air.

Answer 7

True

Question 8

A person smoking 20 cigarettes a day will have a carboxyhaemoglobin concentration in the blood of about ‘__’%. This gives an effect of a non-smoker at a cabin altitude of ‘___‘ft to ‘___‘ft
