(100% Correct Answers) Already Graded A+
ABG Analysis: Questions to Ask Yourself [ Ans: ] 1. Is the
pH normal?

2. Is the CO2 normal?

3. Is the HCO3 normal?

4. Match the CO2 or the HCO3 with the pH

5. Does the CO2 or the HCO3 go the opposite

direction of the pH?

6. Are the pO2 and the O2 saturation normal?

Step One [ Ans: ] The first step in analyzing ABGs is to
look at the pH.

Normal blood pH is 7.4, plus or minus 0.05, forming

the range 7.35 to 7.45. If blood pH falls below 7.35 it

is acidic. If blood pH rises above 7.45, it is alkalotic. If

it falls into the normal range, label what side of 7.4 it

falls on. Lower than 7.4 is normal/acidic, higher than

, 7.4 is normal/alkalotic.

Step One pH [ Ans: ] • look at the pH

• Normal blood pH is 7.4, plus or minus 0.05

• the range 7.35 to 7.45

• blood pH falls below 7.35 it is acidic

• blood pH rises above 7.45, it is alkalotic

• pH is in the normal range,

- label what side of 7.4 it falls on

- Lower than 7.4 is normal/acidic

- higher than 7.4 is normal/alkalotic

Step Two pCO2 [ Ans: ] • examine the pCO2

• Normal pCO2 levels are 35-45mmHg

• Below 35 is alkalotic

• above 45 is acidic.

Step Three HCO3 [ Ans: ] • HCO3 level

• Normal HCO3 level is 22-26 mEq/L
