332 Possible Causes for Hypocapnia

  • Acute Bronchitis

    The role of hyperoxia-induced hypocapnia (that is, the reverse Haldane effect) remains contentious [ 3 , 25 ].[] View Article PubMed Google Scholar Iscoe S, Fisher JA: Hyperoxia-induced hypocapnia: an underappreciated risk.[] It is not widely recognized that hyperoxia causes vasoconstriction, either directly or through hyperoxia-induced hypocapnia.[]

  • Respiratory Alkalosis

    In both groups clear conditioning occurred, but there was no effect of hypocapnia. Results are critically discussed.[] Respiratory alkalosis Synonym Hypocapnia Related conditions Metabolic alkalosis Metabolic acidosis Respiratory acidosis 1.[] Hypocapnia. N Engl J Med. 2002 Jul 4;347(1):43-53.[]

  • Hyperventilation

    KEYWORDS: Conscious sedation; Hyperventilation; Hypocapnia; Tetany[] The hypocapnia and hyperoxia obtained by applying these manoeuvres lengthen the duration of seizures without worsening the quality of the electroencephalographic trace.[] […] examined whether slower pulmonary O 2 uptake (V O 2p ) kinetics in hypoxia is a consequence of: a) hypoxia alone (lowered arterial O 2 pressure), b) hyperventilation-induced hypocapnia[]

  • Acute Hyperventilation

    Abstract Acute hypocapnia decreases CBF, increases hemoglobin affinity for oxygen and causes cerebral tissue hypoxia.[] They will also be taught in a practical way to recognize early clinical signs and symptoms of hypocapnia.[] Granholm L, Siesjö BK (1969) The effects of hypercapnia and hypocapnia upon cerebrospinal fluid lactate and pyruvate concentrations and upon the lactate, pyruvate, ATP, ADP[]

  • Psychogenic Hyperventilation

    […] high lactates are usually associated with acidosis and an increased risk of poor outcome, in patients with psychogenic hyperventilation, high lactates are associated with hypocapnia[]

  • Acidosis

    […] during sustained hypocapnia. 27. 2.[] Often these diseases stimulate ventilation and hypocapnia due to reflex receptors and hypoxia.[] It is completed within 5-10 min from onset of hypocapnia b.[]

  • 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.[] […] 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[] This observation is most likely attributable to the cerebral vasodilatation caused by the hypoxic stimulus during submaximal exercise overriding the hypocapnia-induced vasoconstriction[]

  • Fat Embolism

    Laboratory studies Arterial blood gas findings often demonstrate hypoxia, PaO2 60 mmHg, and hypocapnia Hematologic studies may show non-specific findings such as thrombocytopenia[] Arterial hypoxemia with hypocapnia (decreased ETC02) are generally associated with a pulmonary embolus(Barash).[] Clinical fat embolism syndrome presents with tachycardia, tachypnea, elevated temperature, hypoxemia(lack of oxygen), hypocapnia, thrombocytopenia(low platelets in blood),[]

  • Decreased Diffusion Capacity of the Lung

    Hypocapnia Hypocapnia is P co 2 35 mm Hg.[] Hypocapnia Hypocapnia or hyperventilation is a disorder with abnormally reduced P aCO2 .[] With gross hypoxia of rapid onset hypocapnia depresses respiration, but compensation occurs over about six days.[]

  • Metabolic Acidosis

    Blood gas analysis showed severe metabolic acidosis resulting in hypocapnia and a normal pH ( table 1 ).[] Post-hypocapnia In prolonged hypercapnia renal tubular cells compensate for a prolonged respiratory alkalosis by decreasing reclaimation and generation of HCO 3 (which takes[] Deficiency Aging Extracellular fluid volume expansion Lead Beta Blocker s Prostaglandin Inhibitor Methyldopa Carbonic anhydrase inhibitor Acetazolamide Mefenamic acid Post-hypocapnia[]
