30 Possible Causes for Decreased Expiratory Reserve Volume

  • Morbid Obesity

    Inspiratory and expiratory reserve volumes are decreased, which leads to a lower functional residual capacity and vital capacity.[openanesthesia.org] Also, excessive adipose tissue over the chest decreases the chest wall compliance, and increased abdominal mass forces the diaphragm upwards and reduces lung volumes.[openanesthesia.org]

  • Scoliosis

    Scoliosis and Spinal Disorders will close on 31 st March 2019 and is no longer accepting submissions. You may wish to submit to another BMC journal. Please visit the BMC website for a complete list of our journals. BMC will continue to host an archive of all articles previously published in the journal, and all articles[…][scoliosisjournal.biomedcentral.com]

  • Chronic Obstructive Pulmonary Disease

    Expiratory flow limitation is the pathophysiologic hallmark of chronic obstructive pulmonary disease (COPD), but dyspnea (breathlessness) is its most prominent and distressing symptom. Acute dynamic lung hyperinflation, which refers to the temporary increase in operating lung volumes above their resting value, is a[…][oadoi.org]

  • Restrictive Lung Disease

    BACKGROUND: In healthy volunteers, the single-breath diffusing capacity of the lung for carbon monoxide (DLCO) decreases and DLCO normalized per liter alveolar volume (VA; DLCO/VA) increases if VA is decreased. We hypothesized that comparison of DLCO/VA with its predicted value at predicted total lung capacity[…][ncbi.nlm.nih.gov]

  • Decreased Lung Compliance

    […] in forced VC, which correlates inversely with weight. 24 The effects of uncomplicated obesity are generally reflected more in a significant decrease of the expiratory reserve[archbronconeumol.org] volume, which equals FRCRV at 25 with BMI values under 45 kg/m 26 In patients with uncomplicated obesity, chest and respiratory system compliance is slightly diminished ([archbronconeumol.org] […] independently of the total percentage of body fat. 23 However, forced spirometry in patients with uncomplicated obesity is generally normal, although there may be a small decrease[archbronconeumol.org]

  • Pregnancy

    Tidal volume increases 0.1-0.2 L, about 40%. Expiratory reserve volume (ERV) decreases 15%. Residual volume decreases. Vital capacity does not change.[emedicine.medscape.com] The shift in blood volume leads to ventilatory changes with a decline in vital capacity, ventilation capacity, and expiratory reserve volume. 62 Immersion is ideal for dissipating[doi.org] Functional reserve capacity decreases 18%. Minute volume increases 40%. Forced expiratory volume (FEV1) does not change. PaO2 levels increase, from 100 to 110 mmHg.[emedicine.medscape.com]

  • Obesity
