26 Possible Causes for Moderate Hypoxemia, 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.[] 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[] Asthma is a chronic disorder of the airways that is characterized by reversible airflow obstruction and airway inflammation, persistent airway hyperreactivity, and airway[]

  • Chronic Obstructive Pulmonary Disease

    Chest auscultation revealed decreased breath sounds without rales.[] OBJECTIVE: Introduction: Out of all respiratory diseases COPD is the leading cause of death and is characterized with diffuse non-reversible airway obstruction.[] […] stable COPD and moderate hypoxemia (56–65 mm Hg).[]

  • Pulmonary Emphysema

    When bronchitis is present, the rales peculiar to that affection are noticed. There is a pronounced accentuation of the pulmonary second sound. Diagnosis .[] Eventually, the small airways in the lung become narrowed and destroyed. Asthma is also characterized by airflow obstruction.[] hypoxemia without hypercapnia As the disease progresses, hypoxemia worsens and hypercapnia may develop, with the latter commonly being observed as the FEV 1 falls below 1[]

  • Pulmonary Edema

    However, the patient developed pink frothy sputum with diffuse bilateral rales 30 min later after transported to surgical intensive care unit (SICU).[] obstruction.[] Chest auscultation reveals rales and rhonchi bilaterally.[]

  • Bronchiolitis

    On days 3 to 5, the following symptoms develop: tachypnea, wheezing, rales, and signs of respiratory distress (eg, grunting, nasal flaring, inter-/subcostal retractions).[] Although it is true that a small subset of children with bronchiolitis may have reversible airway obstruction resulting from smooth muscle constriction, attempts to define[] Respiratory Rate Normal Increased respiratory rate Tracheal tug Nasal flaring Marked increase or decrease Tracheal tug Nasal flaring Accessory Muscle Use None or minimal Moderate[]

  • Status Asthmaticus

    Classical signs of consolidation such as egophony, rales, whispered pectoriloquy, dullness to percussion or bronchial breath sounds might be heard.[] Treatment goals • Reverse airway obstruction • Correct Hypoxemia • Prevent or treat complications like pneumothorax and respiratory arrest 4. Etiology 5.[] Cardiovascular symptoms may include tachycardia or hypertension in mild to moderate asthma.[]

  • 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[] Moderate arterial hypoxemia and a significant reduction in vital capacity were present. Thoracentesis revealed sterile chyle with no evidence of malignancy.[] The engorgement of lymphatic ducts with chyle probably reduces lung compliance and worsens small-airway obstruction, and perhaps the lymphatic obstruction that causes this[]

  • 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[] 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[] Fatigue, carbon dioxide retention, and hypoxemia are indications for mechanical ventilation.[]

  • 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[] It is characterized by variable and recurring symptoms, reversible airflow obstruction, and bronchospasm.[] Blood gas testing should be considered particularly for patients with dyspnea or tachypnea who do not have hypoxemia detected with pulse oximetry.[]

  • Bronchiolitis Obliterans

    Auscultation of the lungs revealed prolonged expiration and bilateral crepitant rales. CXR revealed bilateral paracardiac infiltration.[] Bronchiolitis obliterans (BO) also called obliterative bronchiolitis (OB) and constrictive bronchiolitis (CB), is a rare and life-threatening form of non-reversible obstructive[] If the CXR reveals bilateral patchy interstitial infiltrates and severe hypoxemia, the differential diagnosis is limited to moderate or severe viral pneumonia or PCP.[]
