ACID BASE DISORDERS
ACID BASE DISORDERS
If the pH is down, then think what?
Acidosis
If pH is high, then think what?
Alkalosis
If HCO3 is down, then think what?
Acidosis
If HCO3 is high, then think what?
Alkalosis
If PCO2 is down, then think what?
Alkalosis
If PCO2 is high then think what?
Acidosis
This is generally caused by hypoventilation and CO2 buildup in tissues and blood
Respiratory acidosis
This is caused by buildup of organic or fixed acid, impaired H+ elimination at kidneys or HCO3 loss in urine or feces
Metabolic acidosis
This is generally caused by hyperventilation and reduction in plasma CO2 levels
Respiratory alkalosis
This is generally caused by prolonged vomiting and associated acid loss
Metabolic alkalosis
How do you treat respiratory acidosis
improve ventilation; in some cases with bronchodilation and mechanical assistance
How do you treat metabolic acidosis
administration of bicarbonate (gradual) with other steps as needed to correct primary cause
How do you treat respiratory alkalosis
Reduce respiratory rate, allow rise in PCO2
How do you treat metabolic alkalosis
pH below 7.55 - no treatment. pH above 7.55 may require administration of NH4CL
Define Hypokalemia
diuretic users, loose through stool/vomiting. Sx confusion, muscle changes, EKG changes
Define Hyperkalemia
↓ excretion, acidosis, drugs that ↑ K+, hyperthyroidism
Define Hyponatremia
H2O toxicity, CHF, Nephritic syndrome
Define Hypernatremia
dehydration, DI, impaired thirst, limited h20 intake
What is the EKG finding with hyperkalemia?
Peaked “T” waves, prominent “V” waves
What is the EKG finding with hypokalemia?
Decreased amplitude & widening of QRS compliment
What are the normal values for pH
7.35-7.45
What are the normal values for PaCO2
35-45
What are the normal values for PaO2
80-100
What are the normal values for HCO3
21-28
What are the normal values for SPO2
95-100
What is the body's most important buffer substance for hydrogen ions
bicarbonate HCO3
What organs act as the main regulator of bicarbonate HCO3 and CO2 excretion
lungs and kidney
