Respiratory alkalosis

Respiratory alkalosis refers to the increase of pH value (> 7.45) due to the primary reduction of plasma H2CO3 concentration or PaCO2 due to excessive pulmonary ventilation. It can be divided into acute and chronic according to the incidence. In acute patients, hc03 [sup] - [sup] decreased by about 2mmol / L for every 10mmhg (1.3kpa) decrease in PaCO2; In chronic patients, HCO3 [sup] - [sup] decreased to 4 ~ 5mmol / L.
