Which condition is a common indicator for using oxygen therapy?

Hypoxia is a condition characterized by an inadequate supply of oxygen in the body, which makes it a primary indicator for the use of oxygen therapy. Oxygen therapy aims to increase the amount of oxygen available to the tissues, helping to restore normal physiological function. Patients experiencing hypoxia can exhibit symptoms such as shortness of breath, confusion, or cyanosis, which require immediate attention and intervention to prevent potential damage to vital organs.

While asthma, dehydration, and allergies may pose health risks and require treatment, they do not directly indicate the immediate need for supplemental oxygen in the same way that hypoxia does. In cases of asthma, oxygen therapy may be required if hypoxia is present as a result of an asthma attack, but it is not a direct condition that signals the need for oxygen therapy on its own. Dehydration primarily affects fluid balance in the body and does not necessarily impact oxygen levels, while allergies represent an immune response that might lead to respiratory issues but are not a direct cause for oxygen treatment.
