Acidosis Flashcards
Equation
H+ + HCO3- = H2CO3 = Co2 + H2O
PCo2
Respiratory component
HCO3-
metabolic component
Respiratory problem
Primary change is in PCo2
Metabolic problem
Primary change is in HCO3-
Acidosis
Increase in H+
Alkalosis
Decrease in H+
Acidaemia
Increase in H+
Alkalaemia
Decrease in H+
Respiratory acidosis
Increase in H+ due to PCo2
Respiratory alkalosis
Decrease in H+ due to PCo2
Metabolic acidosis
Increase in H+ due to HCO3-
Metabolic alkalosis
Decrease in H+ due to HCO3-
Problem:
Too much H+
Reaction created more Co2
Problem:
Too much Co2
Reaction creates more H+
Problem:
Too little H+
Reaction creates more H+
Problem:
Too little Co2
Reaction creates more Co2
Compensation
Too much H+, lungs blow off Co2
Too much Co2, kidneys get rid of H+
Respiratory Acidosis Causes
Choking
Bronchopneumonia
Respiratory Alkalosis Causes
Overbreathing
Mechanical overventilation
Raised intercranial pressure
Metabolic Acidosis Causes
Impaired H+ secretion
Increased H+ production
Loss of HCO3-
Metabolic Alkalosis Causes
Loss of H+ in vomit
Potassium deficiency
