381 Possible Causes for Decreased Vital Capacity

  • Idiopathic Pulmonary Fibrosis

    […] total lung capacity (TLC) Decreased forced vital capacity (FVC) Decreased diffusing capacity of the lung for carbon monoxide (DLCO) Reduced diffusing capacity is mainly due[] 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[] Chronic dyspnea Dry cough Fatigue Digital clubbing Abnormal chest auscultation End inspiratory fine crackles in bibasilar lung Restrictive pattern in pulmonary function tests: Decreased[]

  • Ankylosing Spondylitis

    Pulmonary function tests show decreased vital capacity and total lung capacity, although residual and functional residual lung volumes were increased.[]

  • Kyphoscoliosis

    Sue displayed a restrictive lung pattern, evidenced by a decreased vital capacity and tidal volume with severe nocturnal dyspnoea, resulting in raised carbon dioxide levels[] Patients with scoliosis suffer from restrictive lung diseasewhich decreased vital capacity, functional residual capacity, tidal volume, and increased respiratory rate. [1][] […] in TLC, vital capacity (VC), and FRC but without changes in residual volume (RV). 5,6 The severity of compression is directly related to the degree of kyphoscoliotic angulation[]

  • Distal Myopathy with Early Respiratory Muscle Involvement

    vital capacity Clinical features from OMIM: 607569 Human phenotypes related to Myopathy, Distal, with Early Respiratory Failure, Autosomal Dominant: 32 (show all 12) # Description[] Pulmonary function test showed decreased vital capacity to 70% of the expected normal value.[] vital capacity with no evidence of obstruction) and a decrease of vital capacity by 20% or more in the supine position compared with standing.[]

  • Flail Chest

    Historically, the free-floating flail segment was deemed responsible for an the increased work of breathing with subsequent hypoxemia and decreased vital capacity; this belief[] Schiller and colleagues published a study in the European Journal of Trauma and Emergency Surgery showing that the procedure significantly improved forced vital capacity in[] "Initially, we focused only on flail chest, but now we offer surgery to people with simple, non-flail rib fractures if their vital capacity is less than 1500 on serial exams[]

  • Pneumothorax

    This reduces the size of the lungs equivalent to the amount of gas decreasing the vital capacity of the lung and reducing the partial pressure of oxygen.[] Due to this there is a decrease in vital capacity as well as a decrease in PaO2 which is the main consequence of a pneumothorax.[]

  • Pulmonary Disorder

    vital capacity, decreased DLCO, usually no obstructive component Multifocal, bilateral alveolar infiltrates ESR, high-resolution CT, lung biopsy Congestive heart failure[] Decreased expansion of the lungs *decreased total, vital, functional residual capacity, and residual volume* Fibrotic Interstitial Lung Disease Can be acute, subacute, or[] Onset at any age; may be associated with history of flu-like illness, collagen vascular disease, or toxic exposure Often subacute presentation with dyspnea, cough, and fever Decreased[]

  • Asbestosis

    […] pulmonary compliance ) Early: decreased DL CO Later: reduced vital capacity and total lung capacity Normal to increased ratio of FEV 1 to FVC Bronchoalveolar lavage Biopsy[] The CO diffusing capacity is decreased and may be the earliest abnormality seen.[] Supradiaphragmatic and pleural reticulonodular opacities / plaques Rounded atelectasis In some cases, pleural effusion HR- CT : Pulmonary function test : Restrictive ventilatory defects (decreased[]

  • Restrictive Lung Disease

    (7) 1.Decreased vital capacity 2.Expiratory flow rates remain normal 3.FEV1/FVC is preserved 4.Increased work of breathing (dyspnea) 5.Rapid, shallow breathing pattern (Leads[] Total lung capacity; VC, vital capacity; FRC, functional residual capacity; RV, residual volume; FEV 1 %, percentage of forced vital capacity in 1 second; MMEFR 25%-75% ,[] Pulmonary function test demonstrates a decrease in the forced vital capacity.[]

  • Myasthenia Gravis

    Monitoring arterial pO 2 or oxygen saturation is not enough, as vital capacity can decrease markedly before these parameters change.[] The best method is regularly to monitor vital capacity, tidal volume, negative inspiratory force and blood gases in such patients.[]
