Hypercapnia; occurs when the CO2 is high. What causes it and why. Respiratory alkalosis is caused by excess respirations that result in excess loss of CO2 . Pathophysiology; As pulmonary ventilation increases, excessive CO2 is exhaled. Resulting hypocapnia leads to reduction of H2CO3, excretion of H+ and HCO3– ions, and rising serum pH.

or HCO3-) is abnormal, then its value should be consistent with the pH (for example, if the CO2 is high, since that causes a drop in pH, the pH should be low). If both of the parameter are abnormal, then usually one is CAUSING the problem, and the other is trying …

Respiratory Alkalosis – high pH, low CO2. Causes – hyperventilation from respiratory causes (asthma, pneumonia) or non-respiratory causes (anxiety, fever, exercise, head injury, infection, salicylate overdose) Symptoms – dizziness, confusion, rapid breathing, numbness and tingling of the extremities. Metabolic Acidosis – low pH, low HCO3

Standard HCO3- (page 122) Because plasma HCO3- levels are influenced by acute alterations in PaCO2, some laboratories report a standard HCO3- (Std HCO3-). Standard HCO3- is defined as the plasma HCO3- concentration that would be present if the PaCO2 were 40 mm Hg.
