A patient is exhibiting a respiratory rate of 22 breaths per minute. What does this indicate?

A respiratory rate of 22 breaths per minute indicates tachypnea, which is defined as an increased respiratory rate typically above 20 breaths per minute in adults. This condition can occur for various reasons, including physical exertion, anxiety, or respiratory issues, as it reflects the body's attempt to meet increased oxygen demand or to expel carbon dioxide more effectively.

Normal respiratory rates for adults usually range from 12 to 20 breaths per minute. When the rate exceeds this range, as in this case, it suggests that the body is in a state of compensating for a condition that may affect its normal function. Understanding respiratory rates is essential in assessing a patient's respiratory status, as abnormalities can be critical for diagnosis and treatment decisions in emergency medical situations.
