Vital signs

Vital signs are a set of measurements used to assess the basic bodily functions of a living being. The four main vital signs are:

1. *Pulse* (heart rate): The number of heartbeats per minute.
2. *Breathing rate* (respiratory rate): The number of breaths taken per minute.
3. *Blood pressure*: The force of blood against the walls of arteries.
4. *Body temperature*: The temperature of the body, usually measured orally, rectally, or via the ear.

Additional vital signs sometimes included are:

- *Oxygen saturation*: The percentage of oxygen in the blood.
- *Pain*: The level of pain or discomfort experienced by the individual.

Vital signs are essential in medical settings to monitor a patient's condition, detect potential health issues, and track the effectiveness of treatments.
