ABGs

Group4

QuestionAnswer
What is the normal range for pH of an ABG? 7.35-7.45
What is the normal range of the PaCO2? 35-45mm Hg
What is the normal range for the SaO2? 93%-100%
What is the normal percent of MetHb in the body? <2.0%
What is the normal percent of COHb in the blood? <3.0%
What is the normal range of base excess on an ABG? +2-(-2)mEq/L
What is the normal range for HCO3? 22-26mEq/L
What is the normal range for CaO2? 16-22ml O2/dl
When is a person considered mildly hypoxic, moderately hypoxic and severely hypoxic based on their PaO2? Mild: 60-80mm Hg Moderate: 40-59mm Hg Severe: <40mm Hg
A good rule of thumb when deciding if a person is well oxygenated or not based off of their PaO2 is? 5 x FiO2
What are the four main values you look at while trying to name a disorder based off on an ABG? pH, PaCO2, HCO3 and Base Excess
How do you determine the last name? If the pH is 7.35-7.45 then it's "normal". If the pH is below 7.35 then it's "acidosis". If the pH is above 7.45 then it's "alkalosis".
How do you determine the middle name? If the pH and PaCO2 are going in opposite directions (like a seesaw) then it is "respiratory". If the pH and HCO3 go in the same direction then it is considered "metabolic". It can also be "combined" if all of the above happen at the same time.
How do you determine if the first name is "compensated/acute" or "uncompensated/chronic"? If CO2 and HCO3 are going in the same direction, the body is trying to compensate. Also, the pH must be within normal limits. If those two things DON'T go in the same direction then it is uncompensated.
How do you determine if the first name is "partially compensated"? If the pH is <7.35 or >7.45, it is considered partially compensated IF CO2 is and HCO3 are going in the same direction.
Is it necessary to put their oxygenation status after the full name of the disorder? YES
