Acute use of oxygen therapy

Area of Science:

• Critical Care Medicine
• Respiratory Therapy
• Clinical Pharmacology

Background:

• Routine administration of high-concentration oxygen to acutely ill patients is a common but potentially harmful practice.
• Oxygen is a potent drug requiring precise administration based on specific indications.
• Current practices often lack documented target ranges and regular monitoring for oxygen therapy.

Purpose of the Study:

• To advocate for a paradigm shift in oxygen administration protocols for acutely ill patients.
• To emphasize the importance of individualized oxygen prescribing based on patient need and monitored response.
• To highlight the risks associated with both hypoxemia and hyperoxemia.

Main Methods:

• Review of current clinical practices and established risks of oxygen therapy.
• Emphasis on the principles of drug titration applied to oxygen administration.
• Recommendation for documented target oxygen saturation ranges and regular patient monitoring.

Main Results:

• Excessive oxygen therapy can lead to hyperoxemia, while insufficient therapy can result in hypoxemia.
• Titration of oxygen therapy is essential to maintain saturation within a safe and effective range.
• Clinical review and adjustment of oxygen therapy are necessary based on changing patient requirements.

Conclusions:

• A culture change is needed to move from routine oxygen administration to a prescribed, monitored approach.
• Titrated oxygen therapy, guided by target saturation ranges, minimizes risks and optimizes patient outcomes.
• Clinicians must regularly assess patients receiving oxygen and adjust therapy to meet evolving needs.
