Imbalances in the exchange of these gases can lead to dangerous respiratory disorders, such as respiratory acidosis or hyperventilation.

Factors that may induce or sustain hyperventilation include: physiological stress, anxiety or panic disorder, high altitude, head injury, stroke, respiratory disorders such as asthma, pneumonia, or hyperventilation syndrome, cardiovascular problems such as pulmonary embolisms, anemia, an incorrectly calibrated medical respirator, and adverse reactions to certain drugs.

Objective: To analyze the nystagmus evoked by hyperventilation in patients with unilateral vestibular schwannoma and to use this information to predict the effects of hyperventilation on individual ampullary nerves. Hyperventilation is the mechanism in ALL cases Hyperventilation (ie increased alveolar ventilation) is the mechanism responsible for the lowered arterial pCO2 in ALL cases of respiratory alkalosis.

Enter and update disclosures at The most widely read and highly cited peer-reviewed neurology journalHyperventilation-induced nystagmus in patients with vestibular schwannoma Other mechanisms of post-hyperventilation hypoxemia include a lack of oxygen intake during prolonged PHA. Also, this is regarded as one of the mechanisms of post-hyperventilation hypoxemia. Imbalances in the exchange of these gases can lead to dangerous respiratory disorders, such as respiratory acidosis or hyperventilation. The alveoli and capillaries in the lungs exchange oxygen for carbon dioxide. NOTE: The first author must also be the corresponding author of the comment.Your role and/or occupation, e.g. In addition, because the oxygen stores in the body are far lower than the carbon dioxide stores, a slow restoration of carbon dioxide after a hyperventilation attack would lead to hypoxemia more rapidly than PaCO 2 … In addition, accumulation of fluid in the alveolar spaces can interfere with gas exchange, causing symptoms such as shortness of breath.
