5,163 Possible Causes for Decreased Vital Capacity, Hyperactive Brainstem Reflexes, Rapid Progression

  • Progressive Bulbar Palsy

    A 12-month-old boy with progressive cranial nerve palsies followed by ventilatory failure demanding artificial ventilation, generalized muscle weakness, and rapid progression[] Pseudobulbar palsy is a clinical syndrome of dysarthria, dysphagia, a hyperactive gag reflex and labile emotional responses.[] Usually the onset is gradual but younger patients may show a more rapid progression.[]

  • Autosomal Recessive Lower Motor Neuron Disease with Childhood Onset

    Reflexes were decreased in the arms and absent in the legs. Vital capacity was normal.[] Disease progression was rapid, and the majority of patients died from respiratory failure within 1–5 years after onset of disease.[] […] tendon reflexes, and Babinski signs.[]

  • Pulmonary Edema

    A typical pattern of respiratory mechanics for a patient with residual pulmonary edema includes decreases in vital capacity and total lung capacity.[] The autopsy revealed severe pulmonary edema, and histology showed air bubbles in the alveolar effusion, suggesting rapid progression of edema.[] […] in patients who ascend over 2,500 meters, particularly if that ascent is rapid.[]

  • Chronic Obstructive Pulmonary Disease

    Other test abnormalities may include Increased total lung capacity Increased functional residual capacity Increased residual volume Decreased vital capacity Decreased single-breath[] Exacerbations have a negative impact on quality of life and lead to more rapid COPD progression, as well as higher health care utilisation and associated costs.[] […] forced expiratory volume in 1 second to forced vital capacity (FEV 1 /FVC) ratio.[]

  • Congestive Heart Failure

    […] in vital capacity by one third from maximum recorded · Tachycardia (heart rate 120 beats/min.)[] Although pharmacological interventions may produce rapid changes in hemodynamic variables, signs and symptoms may improve slowly over weeks or months or not at all. C.[] Minor criteria include extremity edema, night cough, dyspnea on exertion, hepatomegaly, pleural effusion, decrease in vital capacity by one third from normal, and tachycardia[]

  • 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[] A 58-year-old man with a 15-year history of idiopathic pulmonary fibrosis was hospitalized for rapid progression of muscle weakness to bilateral foot drop.[] Acute interstitial pneumonia is characterized by rapid progressive dyspnoea degenerating into respiratory failure requiring mechanical ventilation.[]

  • Pulmonary Fibrosis

    Vital capacity, functional residual capacity, total lung capacity, and forced vital capacity (FVC) all are reduced.[] Ongoing research is evaluating if GERD may be a risk factor for idiopathic pulmonary fibrosis, or if GERD may lead to a more rapid progression of the condition.[] Measures of expiratory airflow are preserved and airway resistance is normal and the forced expiratory volume in 1 second (FEV 1 )/forced vital capacity (FVC) ratio is increased[]

  • Guillain-Barré Syndrome

    capacity less than 60 percent predicted. 22 One retrospective study 21 demonstrated a 40 percent decrease from predicted vital capacity, compared with a 60 percent decrease[] Poor prognosis is associated with rapid progression of symptoms, advanced age and prolonged ventilation.[] Abstract The acute “axonal” form of Guillain—Barre syndrome is characterized by rapid progression to severe widespread paralysis and respiratory dependence within 2–5 days[]

  • Acute Respiratory Distress Syndrome

    progression to ARDS.[] In response, the U-M Critical Care team is undertaking a focused effort to raise awareness about ARDS, its rapid progression, and effective treatment strategies among healthcare[] Rapid progression was common, typically starting on day 4–5 after influenza onset, and intubation was often required within 24 hours after admission [ 26 , 28 , 30 ].[]

  • 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 gives a more rapid IPP rise with earlier mechanical compressive effects and rapid progress to cardiorespiratory collapse, which will be further hastened by trauma and[] 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.[]
