Related to forced vital capacity: pulmonary function test, forced expiratory volume, Restrictive Lung Disease
the power to hold, retain, or contain, or the ability to absorb; usually expressed numerically as the measure of such ability.
closing capacity (CC) the volume of gas in the lungs at the time of airway closure, the sum of the closing volume and the residual volume. See also closing volume.
decreased intracranial adaptive capacity a nursing diagnosis accepted by the North American Nursing Diagnosis Association, defined as the state in which intracranial fluid dynamic mechanisms that normally compensate for increases in intracranial volumes are compromised, resulting in repeated disproportionate increases in intracranial pressure in response to a variety of noxious and nonnoxious stimuli.
diffusing capacity see diffusing capacity.
forced vital capacity the maximal volume of gas that can be exhaled from full inhalation by exhaling as forcefully and rapidly as possible. See also pulmonary function tests.
functional residual capacity the amount of gas remaining at the end of normal quiet respiration.
heat capacity the amount of heat required to raise the temperature of a specific quantity of a substance by one degree Celsius.
inspiratory capacity the volume of gas that can be taken into the lungs in a full inhalation, starting from the resting inspiratory position; equal to the tidal volume plus the inspiratory reserve volume.
maximal breathing capacity maximum voluntary ventilation.
thermal capacity heat capacity.
total lung capacity the amount of gas contained in the lung at the end of a maximal inhalation.
virus neutralizing capacity the ability of a serum to inhibit the infectivity of a virus.
vital capacity (VC) see vital capacity.
forced vi·tal ca·pac·i·ty (FVC),
vital capacity measured with the subject exhaling as rapidly as possible; data relating volume, expiratory flow, and time form the basis for other pulmonary function tests, for example, flow-volume curve, forced expiratory volume, forced expiratory time, forced expiratory flow.
forced vital capacityFVC Pulmonary medicine The volume of air exhaled with maximum effort and speed after a full inspiration; FVC is usually ↓ and thus is a major parameter measured in obstructive airways disease, a term that encompasses both asthma and COPD
forced vi·tal ca·pac·i·ty(FVC) (fōrst vī'tăl kă-pas'i-tē)
Vital capacity measured with the subject exhaling as rapidly as possible.
