What is the normal range for respiratory rate in breaths per minute?

The normal range for respiratory rate in a resting adult is 12 to 20 breaths per minute. This range is established based on physiological data and is widely accepted in medical guidelines. A respiratory rate within this range indicates an efficient exchange of gases in the lungs and generally reflects a stable physiological state. Values outside of this range could indicate respiratory distress or other health issues.

The other options suggest either broader or narrower ranges that do not align with the established norms. The selection of 20-30 breaths falls outside the typical range and suggests hyperventilation or exertion, which is not indicative of a resting state. Other ranges provided may seem plausible but do not accurately reflect the accepted standards established by healthcare professionals. Understanding this normal range is crucial for assessing a patient’s respiratory function in wilderness and other first responder scenarios.
