Question: 1 / 400

What is the normal range for adult respiratory rate?

8-12 breaths per minute

12-20 breaths per minute

The normal range for adult respiratory rate is 12-20 breaths per minute. This range is established based on physiological norms for healthy adults at rest. The respiratory rate can vary with several factors, including age, fitness level, and medical conditions.

A rate of 12-20 breaths per minute indicates effective ventilation, ensuring that the body is adequately exchanging oxygen and carbon dioxide. Rates below or above this range may suggest underlying health issues; for instance, a lower rate could indicate respiratory depression or sedation, while a higher rate could suggest conditions like anxiety, fever, or respiratory distress.

Understanding the normal respiratory rate helps EMTs and healthcare providers identify abnormalities and respond appropriately. Recognizing deviations from this range is crucial for assessing a patient's respiratory status and necessitating further evaluation or interventions.
