Which of the following is a benefit of the recovery position?

The recovery position is particularly useful because it helps to drain blood and fluids from the airway, which can be crucial for an unconscious or semi-conscious casualty who is breathing. By placing a patient in this side-lying position, gravity aids in preventing aspiration of vomit or secretions, thereby protecting the airway and maintaining respiration. This position also reduces the risk of positional asphyxia and is designed to promote the ability to breathe freely.

While the recovery position has many advantages, it may not be suitable for all casualties, especially those with suspected spinal injuries or those requiring immediate cardiopulmonary resuscitation (CPR), as it does not allow for direct chest compressions in a meaningful way. Hence, the selection of the recovery position must be based on the presence of a clear airway and adequate breathing efforts, alongside considerations for the patient's overall condition.
