[Oxygen therapy in acute medicine]

Area of Science:

• Medical Care
• Respiratory Medicine
• Critical Care Medicine

Background:

• Oxygen therapy is essential in acute medical settings.
• Careful indication and monitoring are crucial for safe oxygen administration.
• Understanding risks of hypoxemia and hyperoxia is important.

Purpose of the Study:

• To review historical aspects and physiological principles of oxygen therapy.
• To discuss risks associated with hypoxemia and hyperoxia.
• To present current oxygen saturation targets and conservative administration strategies.

Main Methods:

• Mini-review of historical, physiological, and risk data.
• Presentation of current oxygen saturation target ranges.
• Review of common oxygen delivery systems.

Main Results:

• Oxygen therapy requires careful patient selection and monitoring.
• Risks of hypoxemia and hyperoxia must be managed.
• Conservative oxygen administration is emphasized.
• Appropriate oxygen delivery systems are key in acute care.

Conclusions:

• Conservative oxygen therapy, guided by current targets and patient-specific needs, is recommended.
• Proper use of delivery systems enhances patient outcomes.
• Minimizing risks of hypoxia and hyperoxia is paramount.
