What does "R" stand for in P-MARCH-P?

In the P-MARCH-P acronym, "R" stands for "Respirations." This is a critical component in assessing a casualty's airway and breathing status during the evaluation and management process of a tactical casualty. Properly assessing respirations involves checking for signs of effective breathing, identifying any respiratory distress, and implementing necessary interventions if the casualty is not breathing adequately or has an obstructed airway.

Respirations are vital because they directly correlate with the casualty's ability to receive oxygen, which is essential for cellular function and survival. If a casualty's breathing is compromised, it can lead to rapid deterioration and increased mortality risk.

Understanding the role of respirations in the context of the P-MARCH-P protocol aids corpsmen in making timely and accurate decisions regarding patient care in a tactical environment.
