21 Possible Causes for Dyspnea with Sudden Onset, Hypocapnia, Lip Cyanosis

  • Recurrent Pulmonary Embolism

    […] in onset and may include one or many of the following: dyspnea (shortness of breath), tachypnea (rapid breathing), chest pain of a "pleuritic" nature (worsened by breathing[en.wikipedia.org] Mechanisms of hypoxemia and hypocapnia in pulmonary embolism. Am J Respir Crit Care Med 1995; 152 : 336–347. 10 Frisbie JH, Steele DJR.[nature.com] Arterial or venous blood gas measurement may show an increased alveolar to arterial oxygen (A-a) difference (sometimes called A-a gradient) or hypocapnia; one or both of these[merckmanuals.com]

  • Acute Respiratory Distress Syndrome

    Definition Acute respiratory distress syndrome (ARDS), is a life-threatening condition which is characterised by the sudden onset of severe dyspnea and hypoxaemia [1].[physio-pedia.com] Cyanosis (blue skin, lips, and nails caused by lack of oxygen to the tissues) is often seen.[nlm.nih.gov]

  • Aspiration Pneumonia

    Pink-colored to red sputum (hemoptysis) Bluish tinge of the lips, fingers and/or toes (cyanosis) Causes Aspiration pneumonia is unlikely to arise in a healthy person who is[healthhype.com]

  • Pneumococcal Pneumonia

    BACKGROUND: The serotype-specific effectiveness of 23-valent pneumococcal polysaccharide vaccine (PPV23) against pneumococcal pneumonia has not been established in people aged 65 years or older. We assessed the effectiveness of PPV23 in this population. METHODS: For this multicentre, prospective study, we[…][ncbi.nlm.nih.gov]

  • High Altitude Pulmonary Edema

    People then develop a dry, persistent cough, and often cyanosis of the lips. Another cardinal feature of HAPE is the rapid progression to dyspnea at rest.[en.wikipedia.org] Renal response to short-term hypocapnia in man. Kidney Int 1975;8:376-84. [ PUBMED ] 21. Hackett PH, Roach RC. High altitude cerebral edema.[lungindia.com] The heart rate is usually over 120 per minute, the pulse may be very weak and the lips and fingernail beds may be blue (cyanosis).[publications.americanalpineclub.org]

  • Asthma

    Her attacks are characterized by the relatively sudden onset of dyspnea; they are more frequent in the spring and fall, when they are often preceded by symptoms of rhino-conjunctivitis[doi.org] Extrathoracic respiratory signs should also be systematically looked for, including cyanosis, finger deformation, pulsus paradoxus, and pursed lips breathing.[erj.ersjournals.com] In the early stages of acute, severe asthma, analysis of arterial blood gases usually reveals mild hypoxemia, hypocapnia and respiratory alkalosis.[ncbi.nlm.nih.gov]

  • Congestive Heart Failure

    Common risk factors are male gender, older age, presence of atrial fibrillation, and daytime hypocapnia.[ncbi.nlm.nih.gov] These SRDB cause arousals, hypoxemia-reoxygenation, hypercapnia-hypocapnia, and changes in intrathoracic pressure.[web.archive.org] […] time, which impair the normal buffering of Paco 2 and hydrogen ions and delay the detection of changes in Paco 2 during sleep; and rostral fluid shifts that predispose to hypocapnia[ncbi.nlm.nih.gov]

  • Pneumocystis Carinii Pneumonia

    HIV/AIDS, SLE, organ transplantation, immunosuppressants) sudden onset chest pain and dyspnea suggests pneumothorax Exam tachypnea tachycardia signs of pneumothorax lung exam[lifeinthefastlane.com]

  • Pulmonary Embolism

    Consecutive patients with clinically suspected pulmonary embolism, defined as a sudden onset of dyspnea, sudden deterioration of existing dyspnea, or sudden onset of pleuritic[doi.org] […] to the lips and is negative for chest pain, abdominal distress and peripheral edema.[emsworld.com] Arterial blood gas analysis showed hypoxemia-hypocapnia and D-dimer level was high.[ncbi.nlm.nih.gov]

  • Fat Embolism

    Onset is sudden. Presenting symptoms are myriad and include tachypnea, dyspnea and tachycardia.[journalofethics.ama-assn.org] Laboratory studies Arterial blood gas findings often demonstrate hypoxia, PaO2 60 mmHg, and hypocapnia Hematologic studies may show non-specific findings such as thrombocytopenia[symptoma.com] Tachypnea, dyspnea, and hypoxia appear as a result of ventilation-perfusion abnormalities 12-72 hours after injury.[emedicine.medscape.com]
