7.3 Acid Base Balance Part 4 Flashcards
1
Q
What is the normal range of HCO3?
A
22-26 mEq/L
2
Q
What causes metabolic acidosis?
A
build up of metabolic products such as acetic acid, lactic acid, diabetic ketosis, or extreme diarrhea
3
Q
What is metabolic alkalosis characterized by?
A
higher pH (with normal PCO2 levels) because of a higher HCO3 concentration
4
Q
What causes metabolic alkalosis?
A
vomitting, intake of excess antacids, constipation
5
Q
How does the body work to correct metabolic acidosis or alkalosis?
A
respiratory compensation
6
Q
What are the normal blood serum levels for pH, PCO2 and HCO3?
A
pH = 7.35-7.45
PCO2 = 35-45 mm
HCO3 = 22-26 mEq/L
