The respiratory rate is the rate at which breathing occurs; ... Normal range For humans, the ... Average resting respiratory rates by age are: [11] ...
Average respiratory rates vary between ages, but the normal reference range for people age 18 to 65 is 16–20 breaths per minute. [4] The value of respiratory rate as an indicator of potential respiratory dysfunction has been investigated but findings suggest it is of limited value.
pulmonary fibrosis, Infant Respiratory Distress Syndrome, weak respiratory muscles, pneumothorax: volumes are decreased: often in a normal range (0.8–1.0) obstructive diseases: asthma, COPD, emphysema: volumes are essentially normal but flow rates are impeded: often low (asthma can reduce the ratio to 0.6, emphysema can reduce the ratio to 0. ...
Tachypnea, also spelt tachypnoea, is a respiratory rate greater than normal, resulting in abnormally rapid and shallow breathing. [1]In adult humans at rest, any respiratory rate of 12–20 per minute is considered clinically normal, with tachypnea being any rate above that. [2]

Average values for FEV1 in healthy people depend mainly on sex and age, according to the diagram. Values of between 80% and 120% of the average value are considered normal. [14] Predicted normal values for FEV1 can be calculated and depend on age, sex, height, mass and ethnicity as well as the research study that they are based on.
A normal adult has a vital capacity between 3 and 5 litres. [3] A human's vital capacity depends on age, sex, height, mass, and possibly ethnicity. [ 4 ] However, the dependence on ethnicity is poorly understood or defined, as it was first established by studying black slaves in the 19th century [ 5 ] and may be the result of conflation with ...
Age 0–1 year < 30 breaths per minute; Age 1–3 years < 25 breaths per minute; Age 3–12 years < 20 breaths per minute; Age 12–50 years < 12 breaths per minute; Age 50 and up <13 breaths per minute
