What is the normal respiration rate for adults?

The normal respiration rate for adults typically ranges from 12 to 20 breaths per minute while at rest. This range is considered the standard because it reflects the body's need for oxygen and the process of expelling carbon dioxide. Respiration rates can vary based on factors like age, fitness level, and overall health, but within the defined normal range, the body maintains adequate gas exchange to support metabolic functions.

Understanding this range is critical for CNAs and health professionals as it helps in assessing a patient's respiratory health. If a patient's respiration rate is consistently outside this normal range, it may indicate underlying health issues that require further evaluation. The other ranges provided may either be too low or too high, which do not align with established medical guidelines for adult respiratory rates.
