Which respiratory rate range is generally accepted as adequate for adults?

The generally accepted respiratory rate range for adults is typically between 12 and 20 breaths per minute. This range indicates that the body is maintaining adequate ventilation and gas exchange, which is essential for normal physiological function.

While the choice indicating a range of 8 - 20 may seem plausible at first glance, it's important to recognize that a respiratory rate below 12 breaths per minute could suggest hypoventilation, leading to an increased risk of respiratory acidosis and carbon dioxide retention. This is especially true in clinical settings where monitoring respiratory patterns is crucial for patient safety and effective ventilation management.

In contrast, a respiratory rate above 20 can indicate hyperventilation, which may lead to respiratory alkalosis. Therefore, while the lower end of the range is often cited, maintaining a standard within the 12 - 20 range is critical for clinicians when assessing a patient's respiratory adequacy. This understanding helps healthcare providers recognize abnormalities and intervene accordingly.
