You and your friend are trapped in an overturned ship. To escape you must swim underwater a long distance. You tell your friend it would be a good idea to hyperventilate before making the escape attempt. Your friend condescendingly replies, "What good would that do since your alveolar capillaries are already 100% saturated with oxygen?" Assuming you fight the urge, what would you do and say (based on your knowledge of respiratory physiology)?
