Answer to Question 1

ANS: D
The result is a reduction in intrapulmonary shunting, an improvement in arterial oxygenation, and a decrease in pulmonary vascular resistance and pulmonary arterial pressure.

Answer to Question 2

ANS: A
The half-life of carboxyhemoglobin under HBO at 3 ATA is only 23 min.
