Physiology - Respiratory
It was a cold winter morning and Gabe decided to let the car warm up in the garage before going off to work. About 40 minutes later, his wife was taking garbage to the garage and found him slumped over, breathing rapidly, and very confused. He was taken to hospital where he was diagnosed with acute carbon monoxide poisoning. When a blood sample was taken, his wife noted that it was a deep cherry red colour. His initial treatment was breathing 100% O2.
1. When admitted, Gabe's arterial PO2 would have been decreased. How would it have changed while breathing 100% O2
2. What are the consequences of carbon monoxide poisoning on O2 delivery to the tissues?
Explanation / Answer
Ans:-normally in environment we have 21% fractional 02.when 100% 02 is being administered to game the partial pressure of o2 his high so it diffuses more in alveoli then more in blood.more 02 in blood will combine to haemoglobin. so it changed.
Ans 2:- CO is 200 times efficient than o2 in binding with haemoglobin that is it reduced the concentration of o2 reaching the tissue that may cause hypoxia and then the death of that tissue
