240 Possible Causes for Hypocapnia, Hypoxia

  • Pulmonary Embolism

    Arterial blood gas analysis showed hypoxemia-hypocapnia and D-dimer level was high.[] Hypoxia is an independent predictor of both right ventricular dysfunction and 30-day mortality in these patients.[] Analysis of blood gases reveals arterial hypoxia and hypocapnia.[]

  • Fat Embolism

    In control group, ten patients had hypoxia at the time of admission, only one of them improved and remaining nine patients had persistent hypoxemia even after 72 h.[] Laboratory studies Arterial blood gas findings often demonstrate hypoxia, PaO2 60 mmHg, and hypocapnia Hematologic studies may show non-specific findings such as thrombocytopenia[] We report a case of a 22-year-old man, with multiple long bone fractures from a road traffic accident, who subsequently developed hypoxia, neurological abnormality and petechial[]

  • High Altitude Pulmonary Edema

    Compared with control subjects, numerous hypoxia-related genes were up-regulated in patients with acute HAPE.[] Renal response to short-term hypocapnia in man. Kidney Int 1975;8:376-84. [ PUBMED ] 21. Hackett PH, Roach RC. High altitude cerebral edema.[] A significant population difference in response to hypoxia exist as many highland Tibetan, Ethiopian, and Andean natives developed adaptive mechanisms to extreme hypoxia.[]

  • High Altitude Cerebral Edema

    Prolonged exertion in low oxygen also causes serious hypocapnia , lower carbon dioxide in the bloodstream, which may play a role in HACE.[] The expression of flt-1 mRNA was enhanced after 3 days of hypoxia.[] […] regions of South America and the Himalayas •Extreme altitude, 5490 m ( 18,000 ft) complete acclimatization generally is not possible accompanied by severe hypoxemia and hypocapnia[]

  • Acute Mountain Sickness

    Furthermore, despite an increase in cerebral blood flow after 2 hours of hypoxia (hypoxia vs normoxia: Δ148ml/min(-1) , 95% confidence interval [CI]   58 to 238), by 10 hours[] The current data revealed that on going to high altitude, the subjects experienced not only hypoxia but also developed hypocapnia, therefore, both hypoxia and hypocapnia may[] The hypoxic ventilatory drive causes hypocapnia and a reduction in respiratory drive [11] .[]

  • Decreased Diffusion Capacity of the Lung

    Hypocapnia Hypocapnia is P co 2 35 mm Hg.[] Severe hypoxia may depress central chemoreceptors.[] Hypocapnia Hypocapnia or hyperventilation is a disorder with abnormally reduced P aCO2 .[]

  • Altitude Sickness

    Ventilation fell, and end-tidal PCO2 rose in both groups during 30 min of steady-state hypoxia relative to values observed acutely.[] Severe altitude illness occurs most commonly in this range. [9] Extreme altitude [ edit ] Above 5,500 metres (18,000 ft), marked hypoxemia, hypocapnia , and alkalosis are[] Severe altitude illness occurs most commonly in this range. [10] Extreme altitude Edit Above 5,500 metres (18,000 ft), marked hypoxemia, hypocapnia , and alkalosis are characteristic[]

  • Congestive Heart Failure

    As well, the infant from the high altitude area showed better adaptability to hypoxia.[] Common risk factors are male gender, older age, presence of atrial fibrillation, and daytime hypocapnia.[] […] vera, thyrotoxicosis CHF precipitants Alcohol, cor pulmonale, drug-related–inappropriate medications, non-compliance, fluid and/or sodium intake, fever, hypothyroidism, hypoxia[]

  • Hypoventilation

    This innovative method allows inducing benefits normally associated with hypoxia during swim training in normoxia.[] The opposite condition is hyperventilation (too much ventilation), resulting in low carbon dioxide levels ( hypocapnia ), rather than hypercapnia.[] This kind of exercise may be worth using for performing repeated sprint training in hypoxia.[]

  • Acidosis

    When combining hypoxia and acidosis, the overall changes reflect an additive effect of both conditions alone, indicating that hypoxia and acidosis act by independent mechanisms[] […] during sustained hypocapnia. 27. 2.[] The potential influence of hypoxia and acidosis vs. control conditions on the expression levels of 24 EC-relevant miRNA types was quantitatively accessed via real-time PCR[]
