/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)?
Hyperventilating can slow the co2 level in the body dramatically, it reduce the need for your body to that regular amount of oxygen all the time. Your friend is partly right but at some point you will need to come up for air
