BI‑274 Blood Gas Homework 
	Due 9/29/03

Use my blood gas program to solve these problems.

1.	a)	A patient has an arterial plasma (blood) PO2 of 100 mm Hg, PCO2 of 80.0 mm Hg and a pH of 7.33.  What is her acid‑base status?

b)	A patient has an arterial plasma (blood) PO2 of 100 mm Hg, PCO2 of 23.0 mm Hg and a pH of 7.34.  What is his acid‑base status? 

2.	A mountain climber is resting at an altitude of 18,000 ft above sea level.  She has a hematocrit of 42%, a PO2 of 72.3 mm Hg, a PCO2 of 26.3 mm Hg and a pH of 7.47.  About how long has she been at this altitude?  Explain how you obtained your answer.  Hint: use my blood gas program to find the mountain climber’s base excess and consider the expected time frames for respiratory and renal compensation of acid‑base disturbances.
