What is the normal respiratory rate range for an adult?

The normal respiratory rate for an adult typically falls within the range of 12 to 20 breaths per minute. This range is considered the standard for resting adults in good health. A respiratory rate within this range indicates effective lung function and adequate oxygen exchange during the breathing process.

Understanding this normal range is crucial for health professionals, including psychiatric technicians, as variations outside of these parameters can suggest potential underlying health issues. For instance, a respiratory rate below 12 may indicate bradypnea, possibly due to respiratory depression, while a rate above 20 could signify tachypnea, often associated with conditions such as anxiety, fever, or respiratory distress.

The other ranges provided in the options do not align with established norms for adult respiratory rates and could lead to misinterpretation in a clinical assessment context.
