What is the first step in administering oxygen therapy?

The first step in administering oxygen therapy is to assess the patient's need for oxygen. This assessment is crucial as it helps determine whether the patient is experiencing hypoxemia or other respiratory issues that could benefit from supplemental oxygen. By evaluating the patient's vital signs, pulse oximetry readings, and clinical symptoms, healthcare providers can make informed decisions about the appropriate oxygen therapy needed.

Understanding the need for oxygen not only guides the delivery method but also ensures that the patient receives the correct amount of oxygen required for their condition. This foundational step is essential to provide effective and safe care, as initiating therapy without assessment could lead to either under-treatment or over-treatment of the patient's respiratory needs. Ensuring the patient's needs are identified before any further steps, including setting the flow rate or obtaining a physician's order, is critical in delivering optimal patient care in oxygen therapy.
