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

    In secondary amyloid A amyloidosis resulting from rheumatologic diseases, tumor necrosis factor α blockers have been reported to be effective in the treatment of both arthritis and amyloidosis. However, there have been few reports concerning the alterations of renal tissue histology before and after long-term[…][ncbi.nlm.nih.gov]

  • Scoliosis

    For large scoliosis, 2 strategies to maximize correction include intraoperative traction and/or anterior release. It is unclear which patients will benefit the most form either approach. The purpose of our study is to compare the radiographic, perioperative clinical outcomes, and health-related quality of life (HRQoL)[…][ncbi.nlm.nih.gov]

  • Restrictive Lung Disease

    Restrictive lung disease is uncommon in pregnancy. We reviewed 15 pregnancies in 12 women with restrictive disease due to kyphoscoliosis, neuromuscular disease, or parenchymal lung disease. Median FVC was 40% predicted, and six women (50%) had an FVC 1.0 L. In the 14 pregnancies in which at least two spirometry[…][ncbi.nlm.nih.gov]

  • 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]

  • Chronic Obstructive Pulmonary Disease

    Pulmonary hypertension secondary to respiratory disease most often occurs as a complication of chronic obstructive pulmonary disease, which currently constitutes one of the leading causes of death. Some patients with hypoxaemia reveal "out of proportion" pulmonary hypertension with inappropriate increase of[…][ncbi.nlm.nih.gov]

  • Pulmonary Fibrosis

    Although the majority of patients with Mycobacterium tuberculosis have pulmonary involvement, some cases have pleural involvement as extra-pulmonary sites of infection. We herein report a case of upper lobe-predominant pulmonary fibrosis that developed in a 47-year-old male with a history of bilateral tuberculous[…][ncbi.nlm.nih.gov]
