Hyperventilation


- See: respiratory alkalosis:

- Discussion:
    - induction of hypocapnia is probably the most frequently used technique to reduce intracranial pressure;
    - lowering partial pressure of CO2 to 26-28 mm Hg (3.5-3.7 kPa) reduces cerebral blood flow & thus lowers intracranial pressure;
    - even w/o ability to measure intracranial pressure, inducing hyperventilation may be crucial to improving intracranial pressure during
         emergency room period
