What is the normal range for adult respiratory rate?

The normal respiratory rate for adults ranges from 12 to 20 breaths per minute. This range reflects a healthy adult's breathing pattern when at rest. Respiratory rates outside this range can indicate underlying health issues or distress, such as respiratory diseases, anxiety, or other medical conditions.

Lower respiratory rates, such as those in the ranges of 8 to 12 breaths per minute or 10 to 15 breaths per minute, may suggest a respiratory depression or other issues, while higher rates, such as 15 to 25 breaths per minute, may be indicative of conditions such as anxiety or pain, where the body requires more oxygen. Thus, the range of 12 to 20 breaths per minute is widely accepted as the standard for evaluating adult respiratory health.
