What is the primary reason for administering oxygen to a patient with difficulty breathing?

Administering oxygen to a patient who is experiencing difficulty breathing is primarily intended to enhance oxygenation to tissues. When a patient has respiratory distress, their ability to exchange gases in the lungs may be compromised, leading to decreased oxygen levels in the blood. By providing supplemental oxygen, we can help improve the oxygen saturation in the bloodstream, ensuring that vital organs and tissues receive the oxygen they need to function optimally.

This intervention is crucial because inadequate oxygenation can lead to serious complications, including hypoxia, which can affect the brain and other critical organs. While managing a patient's anxiety, promoting recovery, or preventing coughing fits can be important in the overall care of a patient, the primary physiological goal of oxygen therapy is to ensure that the body’s tissues receive adequate oxygen.
