Medical textbooks suggest that the normal respiratory rate for adults is only 12 breaths per minute at rest. Older textbooks often provide even smaller values (e.g., 8-10 breaths per minute).
Children breathe faster than adults. Body size, weight and activity level influence normal breathing rates. But age is the factor most commonly used to determine normal values. Normal breathing rate ranges from as high as 30 to 60 breaths per minute at birth to as low as 12 to 16 breaths per minute at age 18.
