278 Possible Causes for Decreased Vital Capacity

  • Idiopathic Pulmonary Fibrosis

    […] forced vital capacity, a decrease in forced vital capacity remained an independent risk factor for mortality (decrease 10%; hazard ratio 2.47; 95% confidence interval 1.29[] […] forced vital capacity, a decrease in forced vital capacity remained an independent risk factor for mortality (decrease 10%; hazard ratio 2.47; 95 % confidence interval 1.29[] In a multivariate Cox proportional hazards model controlling for histopathologic diagnosis, gender, smoking history, baseline forced vital capacity, and 6-month change in[]

  • 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[] […] anterior compartment weakness more Laboratory Abnormalities: increased creatine kinase, mild to moderate Respiratory: nocturnal hypoventilation early respiratory failure decreased[]

  • Pulmonary Disorder

    vital capacity, decreased DLCO, usually no obstructive component Multifocal, bilateral alveolar infiltrates ESR, high-resolution CT, lung biopsy Congestive heart failure[] Characteristics of restrictive respiratory disease are decreased forced expired vital capacity and total lung capacity, with increased work of breathing and inefficient exchange[] 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[]

  • 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[] Pulmonary function test demonstrates a decrease in the forced vital capacity. The main symptoms are shortness of breath and cough.[] 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% ,[]

  • Pneumothorax

    The main physiologic consequences of a pneumothorax are a decrease in vital capacity and a decrease in partial pressure of oxygen (PaO 2 ).[] 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.[]

  • 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][] Lung function tests may reveal a diminished inspiratory capacity, vital capacity, and total lung capacity, and blood gas analyses may confirm decreased arterial oxygen saturation[]

  • Respiratory Muscle Paralysis

    A decrease in vital capacity of 30 to 50% when the patient is supine supports the diagnosis of bilateral diaphragmatic paralysis, whereas a decrease in vital capacity of 10[] […] 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[] Lung function test in neuromuscular patient shows a restrictive pattern: total lung capacity (TLC) and vital capacity (VC) reduced while functional residual capacity (FRC)[]

  • Congestive Heart Failure

    […] in vital capacity by one third from maximum recorded · Tachycardia (heart rate 120 beats/min.)[] […] in the vital capacity by one third from maximum recorded, liver enlargement, and bilateral ankle swelling.Minor criteria are acceptable only if they can not be attributed[] […] loss 4.5 kg in 5 days in response to treatment Minor criteria: · Bilateral ankle edema · Nocturnal cough · Dyspnea on ordinary exertion · Hepatomegaly · Pleural effusion · Decrease[]

  • Ankylosing Spondylitis

    Pulmonary function tests show decreased vital capacity and total lung capacity, although residual and functional residual lung volumes were increased.[] Airflow measurements and ventilatory function remain normal in patients with restricted chest wall motion, but vital capacity is decreased and functional residual capacity[]

  • 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[]
