What is the normal adult respiratory rate range?

The main idea here is understanding what a normal resting breathing rate looks like for an adult. In healthy adults, the resting respiratory rate is typically 12 to 20 breaths per minute. This range accounts for normal small variations due to factors like slight anxiety, body position, or measurement technique. Rates higher than 20 breaths per minute are usually considered tachypnea and can signal distress or illness, while rates lower than 12 can be due to fatigue, certain medications, or neurologic impairment. The other options don’t fit because 8–12 is generally too low for a resting adult, 20–24 is usually treated as elevated rather than normal, and 16–22 isn’t the standard reference range used to define normal resting breathing.
