52 Possible Causes for Lung Function Testing Abnormal, Rales, Reversible Airway Obstruction

  • Asthma

    Bilateral crepitant rales and sibilant rhochi were also detected. In his thoracic computerized tomography, the ground glass areas were noted in both lungs.[ncbi.nlm.nih.gov] Asthma is a relatively common condition that is characterized by at least partially reversible inflammation of the airways and reversible airway obstruction due to airway[radiopaedia.org] Pulmonary function tests abnormalities included: high fractional exhaled nitric oxide (FeNO), high lung clearance index (LCI), and elevated diffusing capacity of the lungs[ncbi.nlm.nih.gov]

  • Extrinsic Allergic Alveolitis

    Your provider may hear abnormal lung sounds called crackles (rales) when listening to your chest with a stethoscope.[nlm.nih.gov] They had abnormal lung function tests, abnormal chest radiographs and symptoms of lung disease such as breathlessness, cough, wheeze, fatigue and fever.[bc-legal.co.uk] […] and dyspnea May begin noticing weight loss Chronic (months after continuous exposure) Insidious onset of fatigue, productive cough, progressive dyspnea, cyanosis Bilateral rales[amboss.com]

  • Byssinosis

    They are reversible in the early stages, but prolonged exposure results in chronic airway obstruction, bronchitis, and emphysema with fibrosis, leading to respiratory failure[medical-dictionary.thefreedictionary.com] function tests did not show the relevant abnormalities (no reduction in FEV 1 but small airway disturbance).[thorax.bmj.com] Treatment Therapy for early-stage byssinosis focuses on reversing airway narrowing. Antihistamines may be prescribed to reduce tightness in the chest.[medical-dictionary.thefreedictionary.com]

  • Chronic Obstructive Pulmonary Disease

    Chest auscultation revealed decreased breath sounds without rales.[ncbi.nlm.nih.gov] OBJECTIVE: Introduction: Out of all respiratory diseases COPD is the leading cause of death and is characterized with diffuse non-reversible airway obstruction.[ncbi.nlm.nih.gov] Other test abnormalities may include Increased total lung capacity Increased functional residual capacity Increased residual volume Decreased vital capacity Decreased single-breath[merckmanuals.com]

  • Lymphangioleiomyomatosis

    Airway inflammation, present in 61% of the lung specimens, was not associated with reversible airway obstruction and did not correlate with the severity of airflow obstruction[ncbi.nlm.nih.gov] Previous studies have shown correlations among histological parameters, lung function abnormalities and prognosis in LAM.[ncbi.nlm.nih.gov] The engorgement of lymphatic ducts with chyle probably reduces lung compliance and worsens small-airway obstruction, and perhaps the lymphatic obstruction that causes this[nejm.org]

  • Recurrent Pulmonary Embolism

    The patient had tachypnea (26 breaths/min) without pulmonary rales, bulging of the neck veins, hepatomegaly and a painful swelling of the left calf, with a positive Homans[tmj.ro] It is characterized by variable and recurring symptoms, reversible airflow obstruction, and bronchospasm.[en.wikipedia.org] This test scans for abnormal blood flow through the lungs after a radioactive tracer has been injected and you breathe a radioactive gas. Pulmonary angiogram.[northshore.org]

  • Bronchial Spasm

    The lungs start filling with fluid and I get rales (rattling mucous) bubbling and churning in my bronchial tubes, and can't breathe![benzobuddies.org] In this case, d-penicillamine-induced reversible airway obstruction developed, despite the "go slow--go low" regimen as suggested to reduce the incidence of its side effects[ncbi.nlm.nih.gov] Corticosteroids and inhaled salbutamol in patients with reversible airway obstruction markedly decrease the incidence of bronchospasm after tracheal intubation.[thieme-connect.com]

  • Respiratory Bronchiolitis Interstitial Lung Disease

    Bibasilar inspiratory crackles or rales are usually heard on auscultation. Treatment is based on the underlying cause.[amboss.com] A reversible cause of airway obstruction associated with airway neutrophils and neutrophil products. Am Rev Respir Dis 1989; 140 : 483–492. 36 Colby T, Myers J.[nature.com] On lung function tests, restrictive ventilatory impairment and abnormal diffusion are prominent findings.[pulmonary-fibrosis.net]

  • Idiopathic Pulmonary Fibrosis

    Similar to the sound heard when gently separating the joined strip of velcro on the blood pressure cuff (or jogging shoes), fine crackles have been coined “velcro” rales by[doi.org] Assessing the reversibility of airway obstruction. Chest 1998 ; 114 : 1607 –1612. Pellegrino R, Brusasco V.[dx.doi.org] In our patient population, physiologic testing was more sensitive than HRCT in detecting mild abnormalities in patients with idiopathic pulmonary fibrosis proved by biopsy[ncbi.nlm.nih.gov]

  • Hyperactive Airway Disease

    More severe symptoms – croupy cough, fever 38 c, presence of malaise, lethargy, loss of appetite as confirmed by parents, symptoms and signs of LRI such as wheezing and rales[isanagpur.org] Given a reversible component of airway obstruction, the National Heart Lung and Blood Institute Expert Panel on Asthma supports the use of antiinflammatory therapy. 7 Hence[anesthesiology.pubs.asahq.org] […] hyperreactivity or some sort of reversible airway obstruction.[en.wikipedia.org]
