ABG made easy

normal pH of blood

7.35-7.45

normal HCO3 range

22-26

blood with a pH of 7.7 is considered

base

HCO3 represents

metabolic

HCO3 over 26 is

basic

HCO3 under 22 is

acidic

blood with a pH of 7.0 is considered

acidic

PaCO2 represents

respitory

Normal PaCO2 range

35-45

PaCO2 less than 35 is

basic (opposite from HCO3 and blood)

PaCO2 greater than 45 is

Acidic (opposite from HCO3 and blood)

How do you set up an ABG tictactoe board? draw it out!

Use the tictactoe board to solve this problem!

Your client has a pH of 7.23, PACO2 of 50, and a HCO3 of 30

Step 1:fill out the tic tac toe board

Use the tictactoe board to solve this problem!

Step 2: What kind of issue is the client experiencing? How do you know?

Respirtory acidosis

We know this because we got a tic-tac-toe in the acid column and PACO2 was in it, meaning it is respirtory issue

Use the tictactoe board to solve this problem!

Step 3: Is the client’s body compensating? How can you tell?

Partially compensating

We know this because HCO3 is in the base column, meaning it is on the opposite end of the spectrum trying to bring body back to homeostasis

(if it was in the normal column the body would not be trying to compensate)
