ABG Analysis Latest Update Graded A+

ABG Analysis Latest Update Graded A+ 6 steps to ABG analysis 1. Is the pH within the normal range? 2. Is the CO2 level normal? 3. Is the HCO3 level within the normal range? 4. Determine whether CO2 or HCO3 correlates with the pH. 5. Does CO2 or HCO3 move in the opposite direction to the pH? 6. Are the PO2 and O2 saturation levels within normal limits? 1. Is the pH within the normal range? Normal range is 7.35-7.45 Acidosis occurs when pH is below 7.4 Alkalosis occurs when pH is above 7.4 2. Is the CO2 level normal? Normal range is 35-45 Acidosis occurs when CO2 exceeds 45 Alkalosis occurs when CO2 is below 35 3. Is the HCO3 level within the normal range? Normal range is 22-26 Acidosis occurs when HCO3 falls below 22 Alkalosis occurs when HCO3 exceeds 26 4. Match the CO2 or the HCO3 with the pH value CO2 indicates a respiratory issue HCO3 indicates a metabolic issue ABG Chart Acid-Base (ROME) R-espiratory O-pposite M-etabolic E-qual Arterial Blood Gas Interpretation
