Metabolic alkalosis is a metabolic condition in which the pH of tissue is elevated beyond the normal range (7.35-7.45). This is the result of decreased hydrogen ion concentration, leading to increased bicarbonate, or alternatively a direct result of increased bicarbonate concentrations. The condition may result from: hypokalemia, renal impairment, heart failure, cirrhosis. Ventilation decreases lungs to hold on to CO2. Normal values: PaCO2 > 45 HCO3 >26 the body 's response to metabolic alkalosis is not as complete. This is because we would need to hypo ventilate in order to retain CO2 (acid), but stimulation of brain chemoreceptors with an elevated PaCO2 blunts the hypoventilation required to fully correct the pH. As a result, the respiratory system can only help retain CO2 to no greater than 50-55 mm Hg to compensate for the metabolic alkalosis. A PaCO2 greater than that (> 50-55 mm Hg) suggests an abnormal (primary) respiratory acidosis.
Respiratory alkalosis is a medical condition in which increased respiration elevates the blood pH beyond the normal range (7.35-7.45) with a concurrent reduction in arterial levels of carbon dioxide. The condition can be caused by: central nervous system (CNS) injury to the respiratory control center, extreme anxiety, fever, overventilation during mechanical ventilation. The kidneys dump bicarbonate. Normal values: PaCO2 > 35 HCO3 >22
With respiratory alkalosis, the carbon dioxide level needs to return to normal. Deep breathing can…
