Ventilation (physiology) - Sample Values

Sample Values

Measure Sample value at rest Sample value moderate exercise
Tidal volume 0.5 L 3.0 L
Respiratory rate 12 breaths/minute 30 breaths/minute
Minute ventilation 6.0 L/min 90 L/min
Dead space 0.15 L 0.15 L
Dead space ventilation 1.8 L/min 4.5 L/min
Alveolar ventilation 4.2 L/min 85.5 L/min

Pulmonary ventilation may be evaluated using a breathing tube or spirometer, measuring the movement of the chest and abdominal walls using respiratory inductance plethysmography or by isolating the subject in an enclosed metabolic chamber.

Famous quotes containing the words sample and/or values:

    The present war having so long cut off all communication with Great-Britain, we are not able to make a fair estimate of the state of science in that country. The spirit in which she wages war is the only sample before our eyes, and that does not seem the legitimate offspring either of science or of civilization.
    Thomas Jefferson (1743–1826)

    [University students] hated the hypocrisy of adult society, the rigidity of its political institutions, the impersonality of its bureaucracies. They sought to create a society that places human values before materialistic ones, that has a little less head and a little more heart, that is dominated by self-interest and loves its neighbor more. And they were persuaded that group protest of a militant nature would advance those goals.
    Muriel Beadle (b. 1915)
