Acid-base balance/ventilators
Rule of the B’s.. If the pH & the bicarb are both in the same direction = metabolic
If they are in different directions = respiratory
pH = 7.35-7.45 acidosis/alkalosis
HCO3 (bicarb) = 22

Acid-base balance/ventilators
Rule of the B’s.. If the pH & the bicarb are both in the same direction = metabolic
If they are in different directions = respiratory
pH = 7.35-7.45 acidosis/alkalosis
HCO3 (bicarb) = 22-26 (2+2+2 = 6)
CO2 = 45-35
ex:
pH: 7.30 =
bicarb: 20 = = metabolic acidosis
ex:
pH: 7.58 =
bicarb: 32 = = metabolic alkalosis
ex:
pH: 7.22 =
bicarb: 30 = = respiratory acidosis

You are providing care to a client with the following blood gas results: pH 7.32, CO2 49, HCO3
29, PO2 80 & SaO2 90%. Based on the results, the client is experiencing:
= acidosis, = respiratory
-opioid: CNS depressant.. know the symptoms (sedation, respiratory depression, etc)..
*principle: acid base signs/symptoms..as the pH goes… so goes my patient!!!
-when pH goes up; patient goes up.. (everything gets irritable!)
-when pH goes down; patient goes down! (systems in your body shut down)
…except with potassium:when pH goes up; potassium goes down…when pH goes down;
potassium goes up!
(up) alkalosis: irritibility, hyper-reflexia (3 & 4), tachypnea, tachycardia, borborygmi
(increased bowel sounds), seizure, aspirate..
(down) acidosis: hypo-reflexia, bradycardia, lethergy (obtunded), paralytic ileus (decreased
bowel sounds), coma, respiratory arrest (ambu-bag!!)
Kussmaul breathing is a deep and labored breathing pattern often associated with severe
metabolic acidosis, particularly diabetic ketoacidosis (DKA) but also kidney failure… MAC
Kussmaul!!!!
M: metabolic
AC: acidosis
