105 Possible Causes for Decreased Functional Residual Capacity

  • Idiopathic Pulmonary Fibrosis

    Lung function tests show a restrictive pattern with a decreased diffusing capacity of the lungs for carbon monoxide (DLCO).[radiopaedia.org] Pulmonary function test results may be normal in mild disease or shows restriction pattern (i.e. reduced vital capacity and total lung capacity but near normal residual volume[radiopaedia.org] Pulmonary function test results may be normal in mild disease or show restriction pattern (i.e. reduced vital capacity and total lung capacity but near normal residual volume[radiopaedia.org]

  • Morbid Obesity

    Because awake MO patients already have severe alterations of their respiratory mechanics (10) (decreased chest wall and lung compliance, decreased functional residual capacity[journals.lww.com] Inspiratory and expiratory reserve volumes are decreased, which leads to a lower functional residual capacity and vital capacity.[openanesthesia.org] In general, compared with nonobese patients, functional residual capacity (FRC) is markedly decreased in MO patients, the alveolar-arterial oxygenation gradient is increased[journals.lww.com]

  • Pulmonary Contusion

    Pulmonary contusion causes long-term respiratory dysfunction with decreased functional residual capacity. J Trauma . 1991;31:1203–8; discussion 1208–10.[link.springer.com] residual capacity and decreasing hypoxemia. • Positive end expiratory pressure via mechanical ventilation (PEEP) or non – invasive positive pressure ventilation remains controversial[slideshare.net] Prognosis • Most resolve 5 to 7 days after injury • Signs detectable by radiography are usually gone within 10 days after injury • Lung fibrosis with decreased functional[slideshare.net]

  • Extrapulmonary Alveolar Hypoventilation

    Sv O 2 • Decreased diffusion Widening alveolar-arterial gradient Decreased functional residual capacity Increased work of breathing Interstitial fibrosis Worsening hypercarbia[clinicalgate.com] Increased work of breathing occurs as a result of increased airway resistance, decreased functional residual capacity (FRC), and decreased lung compliance secondary to atelectasis[clinicalgate.com] […] and hypoxemia Increased dead space ventilation Lactic acidosis (related to aerobic metabolism) Alteration in perfusion: • Increased heart rate • Decreased blood pressure[clinicalgate.com]

  • Bronchial Obstruction

    Expiratory duration decreases more than inspiratory duration, and the functional residual capacity (FRC) increases, due to mechanical changes within the airways that lead[ncbi.nlm.nih.gov] During asthma, or induced bronchial obstruction, the function of the muscles is altered, causing changes in respiratory timing.[ncbi.nlm.nih.gov]
