Question | Answer |

acidosis is a proportionate deficit of bicarbonate in ECF | Metabolic Acidosis |
associated with excess of HCO3 bicarbonate, a decrease in H+ ions or both in the ECF | Metabolic Alkalosis |
a primary excess of carbonic acid in the ECF | Respiratory Acidosis |
primary deficit of carbonic acid in the ECF | Respiratory Alkalosis |
Chemoreceptors in the medullar sense the increase in pH and the presences of less carbonic acid and cause the body to breathe either slowly or less deeply | Respiratory Alkalosis |
Increase amounts of of CO2 stimulate the medulla in the respiratory center to increase the respiratory rate and CO2 is expelled, levels of CO2 are reduced | Respiratory Acidosis |
Body compensates by retaining CO2,Respirations become slow and shallow and periods of no breathing may occur, Kidneys attempt to excrete excess H2o and NA ions with the excessive bicarbonate and retain H+ ions | Metabolic Alkalosis |
Lungs attempt to increase the CO2 excretion by increasing the rate and depth of respirations which occurs within a short time | Metabolic Acidosis |
high PaCO2, hyperventilation | respiratory alkalosis |
low PaCO2, hypoventilation | respiratory acidosis |
pH <7.35, PaCO2 >45 mm Hg primary, HCO-3 normal or only slightly elevated | Acute respiratory acidosis |
pH <7.35 or low N Acid, PaCO2 >45 mm Hg primary Acid, HCO3- >26 mEq/L compensatory Base | Chronic respiratory acidosis |
pH > 7.45 Base, PaCO2 <35 mm Hg primary Base, HCO3- < 22 mEq/L compensatory Acid | Respiratory Alkalosis (carbonic acid deficit) |
pH < 7.35 Acid, HCO 3- < 22 mEq/L primary acid, PaCO2 < 35 mm HG Base | Metabolic Acidosis (Base Bicarbonate Deficit) |
pH >7.45 Base, HCO3- >26 mEq/L primary Base, PaCO2 > 45 mm Hg compensatory Acid | Metabolic Alkalosis (Base Bicarbonate Excess) |
