Lectures on Respiratory Alkalosis

Respiratory alkalosis due to prolonged acidosis and too slow central nervous system regulation, still rapid and deep breathing => Respiratory alkalosis

Cause

Alveolar hyperventilation:

Psychogenic deep rapid breathing (nervousness).

Increased metabolism is due to high fever, sepsis, hyperthyroidism.

Salicylate poisoning stimulates the respiratory center.

Lack of oxygen.

Pulmonary edema, pulmonary embolism, pneumonia.

Hepatic coma due to liver failure.

Hyperventilation due to mechanical ventilation.

Too rapid correction of chronic metabolic acidosis.

Respiratory alkalosis due to prolonged acidosis and too slow central nervous system regulation, still rapid and deep breathing => Respiratory alkalosis.

Diagnose

Clinical:

Breathe fast, deeply.

Consciousness disorder.

Tetany due to decreased Ca in the blood.

Arrhythmia due to decreased blood K.

Subclinical:

pH á , PaCO2 â , HCO-3 â.

Acute respiratory alkalosis: reduce HCO3-2mmol/l for 10mmHg reduction in PaCO2.

Chronic respiratory alkalosis: decrease HCO3- 4-5mmol/l for 10mmHg reduction in PaCO2.

Treatment

Treating the cause is key.
