Compared to normal levels, a shift in the Hb02 curve to the right has which of the following effects? 1.     The affinity of Hb for oxygen decreases. 2.     The Hb saturation for a given P02 falls. 3.     The Hb saturation for a given P02 rises.

From 97% and 90% saturation on the oxyhemoglobin dissociation curve, what change occurs in the P02?

Using the normal values for D02 and V02 for a healthy adult, how long would it take to deplete the oxygen stores in the body if an adult experienced a complete respiratory arrest?

What would the total oxygen delivery or DO2 equal if a patient has a CaO2 of 18 vol% and a Cardiac output (QT) of 6L/min? Please show your work on scratch paper and turn in when test is complete. Don’t forget your units!

Calculate the approximate PAO2 given the following conditions (assume R=0.8): FIO2=.40, PB=770 mmHg, PaCO2=31? Please show your work on scratch paper and turn in when test complete. Don’t forget your units!

When can the simplified alveolar gas equation be used? PaC02 less than 60 mm Hg PaC02 greater than 60 mm Hg FI02 0.6 or greater FI02 0.6 or lower

What would the partial pressure of oxygen equal if the barometric pressure was 600 mmHg? Please show your work on your scratch paper and turn in when the test is complete. (Don’t forget your units!)

In a person breathing room air (and with all else being normal), if the alveolar PC02 rises from 40 to70 mm Hg, what would you expect?

Which of the following is true regarding factors that affect the diffusion capacity test? Diffusion capacity decreases with age. Diffusion capacity is indirectly related to an individual’s lung size. Patients with anemia will have a low diffusion capacity.

Why is it necessary to keep the patient’s Pa02 greater than 60 mm Hg?
