What position should an unconscious, adequately breathing patient be placed in?

When dealing with an unconscious but adequately breathing patient, placing them in the laterally recumbent position, also known as the recovery position, is crucial for maintaining an open airway and preventing aspiration. This position allows for drainage of fluids, such as saliva or potential vomit, and reduces the risk of the patient choking, which could occur in a supine or prone position.

Being positioned on their side also facilitates better access for medical personnel should interventions be needed, without compromising airway management. The importance of this position is highlighted in emergency care protocols, where keeping the airway clear is a top priority, especially for unconscious patients who cannot protect their own airways.

The other positions, while having their respective contexts, do not adequately support airway safety in this situation. Supine could lead to airway obstruction, prone is generally not suitable for conscious management in emergencies, and semi-sitting may compromise airway patency and drainage. Thus, the laterally recumbent position serves as the most effective way to ensure safety and preparedness for further medical assistance.
