    1. Arterial Blood Gas
      1. Arterial pH increased
      2. Serum bicarbonate decreased
      3. PaCO2 decreased
    2. Acute Respiratory Alkalosis
      1. PaCO2 decreases by 10 mmHg increases pH by 0.08
      2. Bicarbonate decreases 2 meq/L per 10 mmHg PaCO2 fall
    3. Chronic Respiratory Alkalosis
      1. PaCO2 decrease by 10 mmHg increases pH by 0.03
      2. Bicarbonate decreases 4 meq/L per 10 mmHg PaCO2 fall

Alkalosis, Respiratory (C0002064)

Definition (NCI_FDA) A pathologic condition resulting from accumulation of base, or from loss of acid without comparable loss of base in the body fluids, and characterized by decrease in hydrogen ion concentration.
Definition (NCI) Condition characterized by excessive loss of carbon dioxide from the body, often as a result of hyperventilation due to psychogenic or physical factors.
Definition (MSH) A state due to excess loss of carbon dioxide from the body. (Dorland, 27th ed)
