Verified step by step guidance

Begin by verifying the physician's order for oxygen therapy. This ensures that the treatment is authorized and that you are aware of the prescribed flow rate and delivery method.

Once the order is verified, assess the patient's current oxygen saturation levels using a pulse oximeter. This helps determine the urgency and effectiveness of the therapy.

Select the appropriate oxygen delivery device based on the patient's needs and the physician's order. Common devices include nasal cannulas, face masks, or non-rebreather masks.

Adjust the flow rate on the oxygen tank according to the physician's order. Ensure that the flow rate is set correctly to deliver the prescribed amount of oxygen.

Monitor the patient closely after initiating oxygen therapy, observing for any signs of improvement or adverse reactions, and adjust the therapy as needed.
