What is the respiratory rate for an adult according to the provided guidelines?

The respiratory rate for a normal adult is typically considered to be between 12 and 20 breaths per minute. Within this range, 20 breaths per minute is often cited as an upper limit for what remains a healthy and normal respiratory pattern in adults. A rate of 15 breaths per minute falls comfortably within this range, indicating normalcy in the context of adult respiration.

This value is significant because it reflects adequate ventilation and gas exchange, both of which are critical for maintaining proper oxygen levels in the blood and removing carbon dioxide. Understanding these values helps paramedics assess patients effectively, especially in emergency situations where respiratory function may be compromised.

The other choices indicate either more rapid respiratory rates, which may suggest conditions such as anxiety, pain, or pathological respiratory challenges, or rates that are slower than normal, indicating potential respiratory distress or other health issues.
