New York State Emergency Medical Technician (EMT) Practice Exam

What is the normal range for adult resting respiratory rates?

1. 8-12 breaths/min

2. 12-20 breaths/min

3. 20-30 breaths/min

4. 30-40 breaths/min

The correct answer is: 12-20 breaths/min

The normal range for adult resting respiratory rates is typically between 12 to 20 breaths per minute. This range is considered indicative of a healthy respiratory function in adults at rest, reflecting an adequate exchange of oxygen and carbon dioxide during the breathing process. Respiratory rates outside of this normal range can indicate various health issues. For example, rates below 12 breaths per minute may suggest bradypnea, which can occur in conditions like respiratory failure or overdose of certain medications. Conversely, rates above 20 breaths per minute may indicate tachypnea, which can be seen in situations of physical exertion, anxiety, or respiratory distress. Understanding the normal respiratory rate is crucial for EMTs and healthcare providers, as it can serve as an important vital sign for assessing a patient’s overall respiratory health and the need for further intervention.
