The Respiratory System and Urinary System work hand-in-hand to maintain blood pH. Depending upon the cause, each system will utilize mechanisms to increase or decrease pH levels. Sometimes, one system works sufficiently to alleviate the acidosis or alkalosis. At other times, both systems will work together to bring pH levels within normal range. Compensation is the term used to describe how one system assists the other in normalizing blood plasma pH. Respiratory compensation works quickly, using brainstem respiratory centers to eliminate or retain CO2 levels in the blood and works more quickly. Renal compensation takes more time, changes HCO3- levels and generally has a greater ability to restore normal pH values. Based on the information given for each of the cases below, indicate whether there is an alkalosis or acidosis present. Assume that appropriate time has lapsed to cause the lab results listed. 1. For each case, indicate whether the cause is metabolic or respiratory. 2. For each case, indicate whether the condition is being compensated. 3. For each case, list 1 possible cause for the condition. Case #1: pH = 7.63 PCO2 = 11 mm Hg HCO3- = 19.5 mEq/L Case #2: pH = 7.22 PCO2 = 38 mm Hg HCO3- = 12.0 mEq/L
