In the OPQRST model, what does 'S' signify?

In the OPQRST model, 'S' signifies Severity. This is a critical component in assessing a patient's condition during an emergency. The severity aspect allows responders to gauge how intense or debilitating the symptoms are for the individual. Understanding the severity can help prioritize care, guide treatment decisions, and communicate the urgency of the situation to medical personnel.

The other elements in the OPQRST model—Onset, Provocation, Quality, Radiation, and Timing—each serve specific purposes in gathering comprehensive information about a patient's condition. Severity focuses on the degree of discomfort or pain, making it key in evaluating how significantly the condition affects the patient. Thus, assessing severity helps responders to establish a clear picture of the situation and directs appropriate interventions.
