What is the normal breathing rate for an adult after puberty?

The normal breathing rate for an adult after puberty is typically between 12 and 20 breaths per minute. This range is considered standard for resting adults and reflects a healthy respiratory rate, which is essential for ensuring that the body receives enough oxygen and is able to expel carbon dioxide efficiently.

Breathing rates can vary based on several factors, such as physical activity, emotional state, and individual health conditions, but in a baseline, relaxed state, 12 to 20 breaths per minute is widely accepted in medical references. Monitoring respiratory rate is critical in first aid and CPR contexts, as deviations from this normal range can indicate distress or respiratory issues that may require immediate intervention.
