  1. 1. PRESENTED BY: Mr.Sanil Varghese
  2. 2. DEFINITION An arterial blood gas analysis is a blood test taken from an artery, that measures the amount of oxygen and carbon dioxide that is found in the blood.
  3. 3. PURPOSE To evaluate 1. Respiratory status 2. Metabolic status 3. Acid base balance
  4. 4. SITES OF EXTRACTION:  RADIAL ARTERY  BRACHIAL ARTERY  FEMORAL ARTERY
  5. 5. PROCEDURE
  6. 6. ALLEN’S TEST
  7. 7. PROCEDURE
  8. 8. COMPLICATIONS:  EXCESS BLEEDING  BRUISING AT THE PUNCTURE SITE  CIRCULATION IMPAIREMENT
  9. 9. COMPONENTS:  pH: Measurement of alkalinity based on the presence of H+ ion.  SaO2: Measurement of arterial oxygen saturation.
  10. 10. Contd: • HCO3 : The calculated value of the amount of bicarbonate in the blood stream • B.E : The base excess indicates the amount of excess insufficient level of bicarb system.
  11. 11. NORMAL VALUES:  pH 7.35 - 7.45  PaCO2 35 - 45 mmHg  PaO2 80 - 100 mmHg  HCO3- 22 - 26mEq /L More than 95% -2 to +2  SaO2  B.E
  12. 12.  ASSESS THE pH  ASSESS THE PaCO2  ASSESS THE HCO3-
  13. 13. R =O M=E
  14. 14. 1. Air bubbles in the syringe. 2. Inadvertent venous sample. 3. Anticoagulant effect. 4. Dilution of sample. 5. Effects of metabolism of WBC’s in sample.
