DictionarySeeICinspiratory capacity
inspiratory capacity[in′spī·rə‚tȯr·ē kə′pas·əd·ē] (physiology) Commencing from expiratory standstill, the maximum volume of gas which can be drawn into the lungs. inspiratory capacity
capacity [kah-pas´ĭ-te] 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. Subdivisions of total lung capacity: TLC, total lung capacity; V, tidal volume; IC, inspiratory capacity; FRC, functional residual capacity; ERV, expiratory reserve volume; VC, vital capacity; RV, residual volume.

Synonym(s): complementary airinspiratory capacityn. The volume of air that can be inhaled after normal inspiration.lung volumes Physiology A group of air 'compartments' into which the lung may be functionally divided Lung volumes
Expiratory reserve capacity–ERV The maximum volume of air that can be voluntarily exhaled Functional residual capacity (FRV) Volume left in the lungs at the end of a normal breath which is not normally part of the subdivisions Inspiratory capacity–IC The maximum volume that can be inhaled Inspiratory Reserve capacity–IRC The maximum volume that can be inhaled above the tidal volume Tidal volume–VT The normal to-and-fro respiratory exchange of 500 cc; vital capacity is the maximum amount of exhalable air; after a full inspiration, which added to the residual volume, is the total lung capacity Total lung capacity–TLC The entire volume of the lung, circa 5 liters Vital capacity–VC The maximum volume that can be inhaled and exhaled
