Acid-Base Balance, Ventilators

Acid/Base Balance
To solve acid-base disorders, it is important to know
the normal values for pH, CO2 and HCO3
(bicarbonate).

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
Nu

- If pH is >7.45, the acid-base imbalance is alkalotic
rs

Now, to determine if the imbalance is metabolic or respiratory, determine whether
HCO3 goes in the same or opposite direction with pH
in


Rule of the Bs: If pH and Bicarb move both in the same direction, then the acid-
gE

base imbalance is metabolic … Otherwise, it is respiratory.

Example #1
- pH 7.3 Acidosis
m


- HCO3 20 Metabolic
Su

- This is an example of metabolic acidosis
cc

Example #2
es

- pH 7.58 Alkalotic
- HCO3 32 Metabolic
s


- 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
