For whom is emergency oxygen typically administered?

Emergency oxygen is typically administered to individuals experiencing respiratory distress because it helps to increase the concentration of oxygen in the bloodstream, thereby providing vital support to individuals whose breathing is compromised. In situations such as asthma attacks, choking incidents, or other emergencies that impair normal respiratory function, the immediate availability of supplemental oxygen can be life-saving.

The other options do not align with the typical indications for emergency oxygen use. While individuals with allergies might experience symptoms that affect breathing, they do not universally require oxygen unless there is a severe reaction impacting respiratory function. Fatigue is a different condition and generally does not warrant oxygen administration, as it is not primarily a respiratory issue. Similarly, giving oxygen to individuals who are healthy does not have a clinical justification, as they do not have a need for supplemental oxygen in a non-emergency situation.
