What vital sign is typically assessed using a sphygmomanometer?

A sphygmomanometer is specifically designed to measure blood pressure, which is a vital sign that indicates the force of blood against the walls of the arteries. This measurement is crucial for assessing cardiovascular health and identifying conditions such as hypertension (high blood pressure) or hypotension (low blood pressure).

In the context of vital signs, blood pressure is a key indicator of the circulatory system's status and overall health. Monitoring blood pressure helps EMTs evaluate a patient's condition and make informed decisions about their treatment and transport. Understanding blood pressure and its implications can guide the recognition of a variety of medical emergencies, including shock, heart attack, and stroke.
