What are the normal respiratory rates for adults?

The normal respiratory rate for adults is established to be between 12 to 20 breaths per minute. This range reflects the typical ventilatory response of a healthy adult at rest, taking into consideration factors such as age, physical condition, and overall health.

A respiratory rate within this range indicates effective gas exchange and adequate oxygenation in the body. Rates below this range can suggest respiratory depression or other medical conditions, while rates above may indicate increased metabolic demand or respiratory distress. Recognizing this normal range is essential for paramedics, as deviations can signal underlying health issues that require prompt assessment and intervention.

Other options fall outside the established normal limits, which can lead to misconceptions about what constitutes respiratory distress or normalcy in adults. Understanding and identifying the correct range is critical in emergency care settings.
