Lecture 1 • Mark Klimek • 92:21
Acid/Base Balance (Start times:
30:00)
In order to solve acid-base disorders,
it is
important to know the normal values
for
pH, CO2 and HCO3 (bicarbonate),
which
are shown below
• pH 7.35 to 7.45
• CO2 35 to 45
• HCO3 22 to 26
The first value to look at in an acid-base disorder is the pH
• If pH is <7.35, the acid-base imbalance is acidotic
• If pH is <7.45, the acid-base imbalance is alkalotic
Now, to determine if the imbalance is metabolic or respiratory , determine whether
HCO3 goes in the same or opposite direction with pH
• Rule of the Bs: If pH and Bicarb move both in the same direction, then
the acid-base imbalance is metabolic … Otherwise, it is respiratory
Example #1
• pH 7.3 Acidotic
, • HCO3 20 Metabolic
• This is an example of metabolic acidosis
Example #2
• pH 7.58 Alkalotic
• HCO3 32 Metabolic
• This is an example of metabolic alkalosis
Example #3
• pH 7.22 Acidosis
• HCO3 35 Respiratory
• This is an example of respiratory acidosis
As the pH goes, so goes my patient, except for Potassium …
That means • If pH is low, everything is low, except
potassium
• If pH is high, everything is high, except potassium
Page 3 of 92
If pH goes over 7.45, this is alkalosis
• Therefore everything is up: tachycardia, tachypnea, HTN, seizures, irritability,
spastic, diarrhea, borborygmi (increase bowel sounds), hyperreflexia (3+, 4+) •
However, potassium is opposite. Therefore, hypokalemia • What is the nursing
intervention?
o Pt need suctioning because of seizures
If pH goes below 7.35, this is acidosis
• Therefore, everything is down: bradycardia, constipation, absent bowel sounds,
flaccid, obtunded, lethargy, coma hyporeflexia (0, 1+), bradypnea, low BP •
However, potassium is high (hyperkalemia) • What is the nursing
intervention?
o Pt needs to be ventilated with an Ambu bag—respiratory arrest
, So, remember that “MAC Kussmaul” is the only acid-base imbalance
to cause M etabolic AC idosis with Kussmaul respirations
Causes of Acid/Base imbalance
First ask yourself, “Is it LUNG? … If yes, then it is respiratory
• Then ask yourself, “Are they overventilating or underventilating ? o If
UNDERventilating, then pick acidosis—pH is under 7.35
o If OVERventilating, then it is alkalosis, pH is over 7.45
What type of acid-base derangement is present in the
following condition? • In labor? o Respiratory
alkalosis … Overventilating —pH increases …
Alkalosis) • Drowning?
o Respiratory acidosis … Underventilating —pH decreases …
Acidosis • Pt is on PCA (patient-controlled anesthesia)
pump? o Ventilation is down … Respiratory acidosis
If it is not LUNG, then it is metabolic . If the patient has
prolonged
gastric vomiting or suction (sucking out acid), pick alkalosis
• For everything else that isn’t lung, pick metabolic acidosis
• So, when you don’t know what to pick, pick metabolic
acidosis
Tip
• Set your default setting to Metabolic Acidosis
• Always pay attention to modifying phrase rather than
original noun

Ventilator
A ventilator is a machine designed to move breathable air into and out of the
lungs, aids patients who are physically unable to breathe, or breathing
