What constitutes a normal respiratory rate for an adult at rest?

A normal respiratory rate for an adult at rest typically ranges from 12 to 20 breaths per minute. This range is widely accepted in medical contexts as it reflects the typical physiological response of a healthy adult not under stress or exertion.

Breathing is a vital sign, and these values are important indicators of respiratory function and overall health. Rates lower than this range may suggest bradypnea (slower than normal breathing), while rates higher may indicate tachypnea (faster than normal breathing), both of which could signal underlying health issues.

The significance of establishing a normal respiratory rate lies in its use for assessing a patient’s condition. A respiratory rate outside of this normal range could prompt further evaluation and monitoring. This understanding is crucial for paramedics and healthcare professionals when providing care in emergency situations.
