Which factors should be assessed before initiating oxygen therapy?

Before initiating oxygen therapy, it is crucial to assess the patient’s oxygen saturation levels and underlying health conditions. Oxygen saturation, typically measured using pulse oximetry, provides direct insight into how effectively the patient’s blood is oxygenated. This measurement helps in determining whether the patient is hypoxemic and requires supplemental oxygen.

Additionally, understanding the patient's underlying health conditions is essential. Conditions such as chronic obstructive pulmonary disease (COPD), asthma, or heart failure can significantly influence the decision regarding the amount and method of oxygen administration. Each of these conditions may respond differently to oxygen therapy, and tailoring the approach based on the patient's specific health status ensures both safety and efficacy in treatment. By assessing these factors, healthcare providers can optimize the use of oxygen therapy while minimizing potential risks and complications.
