Arterial Blood Gases (ABG)rated A+ 2023

Arterial Blood Gases (ABG)rated A+ 20231. ABG Values - correct answer pH 7.35 - 7.45 paCO2 (Respiratory) 45 - 35 HCO3 (Metabolis) 22 - 26 2. Check for Acidosis or Alkalosis - correct answer The first thing you need to determine when checking ABG results is the acidity of the blood which is determined by the value of the pH. The pH level in a healthy human should be between 7.35 to 7.45. Your body is constantly striving to keep pH in balance. pH level below 7.35 is Acidosis pH level above 7.45 is Alkalosis 3. Determine If the Acid Base is Respiratory or Metabolic - correct answer paCO2 = Respiratory HCO3 = Metabolic 4. Remember ROME - correct answer Respiratory Opposite When pH is up, PaCO2 is down = Alkalosis When pH is down, PaCO2 is up = Acidosis Metabolic Equal When pH is up, HCO3 is up = Alkalosis When pH is down, HCO3 is down = Acidosis 5. And yes, ABG problems work using the Tic-Tac-Toe method. All you have to do is make a blank chart a bit like a tic-tac-toe chart. - correct answer Tic Tac Toe 6. Mark the Chart - correct answer Using the lab result values, mark them on your Tic-Tac-Toe chart. Now begin with this given example. pH 7.26, paCO2 32, HCO3 18 pH is LOW = ACID so place pH under Acid paCO2 is LOW = BASE so place paCO2 under Base HCO3 is LOW = ACID so place HCO3 under Acid 7. Match It up - correct answer In this step, look at which column matches up with the pH. In this case HCO3 goes with pH. HCO3 is considered Metabolic (shown in step 3), and both are under Acid, so this example implies Metabolic Acidosis. 8. Determine Compensation - correct answer The last step is to determine if the ABG is Compensated, Partially Compensated, or Uncompensated. If pH is NORMAL, PaCO2 and HCO3 are both ABNORMAL = Compensated If pH is ABNORMAL, PaCO2 and HCO3 are both ABNORMAL = Partially Compensated If pH is ABNORMAL, PaCO2 or HCO3 is ABNORMAL = Uncompensated Therefore this ABG is METABOLIC ACIDOSIS, PARTIALLY COMPENSATED . Example: pH 7.44, PaCO2 30, HCO3 21 - correct answer pH is NORMAL = NORMAL so place pH under Normal PaCO2 is LOW = BASE so place PaCO2 under Base HCO3 is LOW = ACID so place HCO3 under Acid
