25 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]

  • 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]

  • Respiratory Muscle Paralysis

  • Ankylosing Spondylitis

    1 Recommendations 1.1 Secukinumab is recommended, within its marketing authorisation, as an option for treating active ankylosing spondylitis in adults whose disease has responded inadequately to conventional therapy (non-steroidal anti-inflammatory drugs or TNF‑alpha inhibitors). The drug is recommended only if the[…][nice.org.uk]

  • Scoliosis

    Scoliosis is caused by the lateral displacement and rotation of the vertebral bodies. It is most common during periods of rapid somatic growth. Scoliosis impedes on the movement of the ribs, places the respiratory muscles at a mechanical disadvantage and displaces the various organs of the thoracic cavity. Scoliosis[…][ncbi.nlm.nih.gov]

  • Restrictive Lung Disease

    Restrictive lung diseases (or restrictive ventilatory defects) are a category of extrapulmonary, pleural, or parenchymal respiratory diseases that restrict lung expansion, resulting in a decreased lung volume, an increased work of breathing, and inadequate ventilation and/or oxygenation. Pulmonary function test[…][en.wikipedia.org]

  • Lobectomy or Pneumonectomy

    Researchers at McMaster University (Hamilton, ON) explored whether a surgeon's expertise influences procedural choice. The results of a new study of more than 8000 non-small cell lung cancer (NSCLC) patients undergoing surgical resection by 124 physicians showed that surgeons who perform more surgeries are less[…][sciencedaily.com]
