When available, why is it beneficial to administer emergency oxygen to a person who is unresponsive due to drowning?

Administering emergency oxygen to a person who is unresponsive due to drowning is crucial because it increases the amount of oxygen delivered to their system. When a person drowns, their airways may be obstructed, and they may have inhaled water, which can lead to a lack of oxygen in the bloodstream. By providing supplemental oxygen, you help to restore oxygen levels and promote recovery of vital organ function.

This intervention is particularly important as the brain and other organs require adequate oxygen to function properly; a lack of it can lead to irreversible damage or death. The administration of oxygen can support the body’s natural recovery processes until further medical help arrives.

While the other options mention effects that are not directly related to the primary benefit of oxygen delivery, they do not address the key physiological need for restoring adequate oxygenation in an unresponsive victim.
