ACID BASE BALANCE
1. Rule of B’s
a. If the pH and the Bicarb are Both in the same direction, then it is
metabolic
2. Signs and Symptoms
a. As the pH goes, so goes my patient, except for potassium
i. as pH goes up, systems gets irritable
ii. as pH goes down, systems shut down
1. UP pH (Alkalosis)
a. HTN
b. Tachycardia
c. Tachypnea
d. Seizures
e. Irritability
f. Spastic
g. Diarrhea
h. Borborygme
i. Hyperreflexia, (3,4)
j. Hypokalemia
2. DOWN pH (Acidosis)
a. Hypotension
b. Bradycardia

g. Hyperkalemia
h. Lethargy
i. Obtunded (one step down from
lethargy)
j. Paralytic ileus
k. Coma
, l. Respiratory arrest
b. MacKussmaul
i. The only acid base to cause Kussmaul respirations is Metabolic
Acidosis
3. Causes
a. First ask yourself, “Is it lung?” If yes, then it’s respiratory. Then ask
yourself; “Are they overventilating or underventilating. If
overventilating, pick alkalosis. If underventilating, pick acidosis.
b. If it is not lung, then it is metabolic. If the patient has prolonged gastric
vomiting or suction, pick alkalosis. For everything else that isn’t lung, pick
metabolic acidosis. When you don’t know what to pick, choose
metabolic acidosis.
