The normal respiratory rate for an adult is considered to be between 12 and 20 breaths per minute. This range is established based on physiological studies and clinical observations of healthy adults at rest. The body requires a certain number of breaths to efficiently exchange oxygen and carbon dioxide, and this range reflects the typical rate at which this exchange occurs in a resting state.

When the respiratory rate falls within this range, it indicates that the body's respiratory system is functioning effectively to meet metabolic needs. Rates outside this range can signal potential health issues; for example, a significantly lower rate could indicate respiratory depression, while a higher rate may suggest conditions like anxiety, fever, or an underlying medical condition requiring attention.

The other ranges listed do not align with the accepted norms for adult respiratory rates. Understanding normal vital signs, including respiratory rates, is crucial for EMTs as deviations can be critical indicators of a patient's condition.
