What are vital signs?

Vital signs are clinical measurements that provide critical information about a patient's essential body functions. These measurements typically include parameters such as heart rate, blood pressure, respiratory rate, and temperature. Understanding these signs is crucial in assessing the physiological status of a patient and helps healthcare professionals identify potential medical issues.

By monitoring vital signs, clinicians can quickly determine whether a patient's body is functioning within normal limits or if there is a need for immediate medical intervention. For instance, an elevated heart rate may indicate stress, dehydration, or an underlying medical condition, while a significant deviation in blood pressure can suggest problems such as hypertension or shock. Thus, vital signs serve as a fundamental aspect of patient assessment and ongoing monitoring in a healthcare setting.
