The typical respiratory rate for a healthy adult at rest is 12â20 breaths per minute. Average resting respiratory rates by age are: 1  birth to 6 weeks: 30â60 breaths per minute. 2  6 months: 25â40 breaths per minute.uman respiration rate is measured when a person is at rest and involves counting the number of breaths for one minute by counting how many times the chest rises.
Normal Breathing Pattern (Normal Respiration Cycle). Modern physiology textbooks suggest the following parameters of the normal breathing pattern (normal respiration) at rest for healthy subjects: - inhalation is 1.5-2 s. - exhalation is 1.5-2 s. - automatic pause of almost no breathing is 2 s. - tidal volume (the depth of inhalation) is 500-600 ml. - breathing frequency (or Rf-respiratory frequency or respiratory rate) is 10-12 breaths/min. The international physiological norm for the breathing rate at rest is 6 L/min (for a 70-kg man). Normal stress-free breath holding time after usual exhalation (that correlates with body-oxygen content) is 40 s. References for medical textbooks that provide these values are below.
