Lab value showing METABOLIC acidosis:
HCO3 less than 22 mEq/L
Lab value showing METABOLIC alkalosis:
HCO3 greater than 26 mEq/L
Lab value showing RESPIRATORY acidosis:
PaCO2 greater than 45 mmHg
Lab value showing RESPIRATORY alkalosis:

Alkalosis
pH above 7.45
(7.4 is normal)
Acidosis:
pH below 7.35
(7.4 is normal)
Clinical manifestations of METABOLIC ACIDOSIS:
1) hyperkalemia
2)anorexia, nausea, and vomiting
3) warm, flushed skin
4) cardiac dysrhythmias and CNS dysfunction
5) headache, diarrhea, tremors
Clinical manifestations of METABOLIC ALKALOSIS:
1) cardiac dysrhythmias; seizures; confusion; muscle twitching, agitation
2) elevated pH; elevated HCO3; normal PaCO2 or elevated if compensation occurs.
Clinical manifestations of RESPIRATORY ACIDOSIS:
1)lowered pH; elevated PaCO2; HCO3 is normal or elevated (with renal compensation)
2) vasodilation; cardiac dysrhythmias, tachycardia, somnolence, decreased ventilation
Clinical manifestations of RESPIRATORY ALKALOSIS:
1) elevated pH; lowered PaCO2; HCO3 normal or low due to compensation
2) nausea, vomiting, tingling of fingers
