NURS3403 Lecture : Chapter 8 Interpreting ABG's
Document Summary
Chapter 8 interpreting abg"s step 1: check ph if low (<7. 35) - acidosis if high (>7. 45) - alkalosis. Step 2: check pco2 (resp. ) normal 30-50 mmhg. If low (<35, too few acids) and ph >7. 45 - respiratory alkalosis. If high (>50, too many acids) and ph <7. 35 - respiratory acidosis. Step 3: check hco3 - (metabolic) normal: 22 -26 meq/l if low (< 22, too little base) and ph <7. 35 -- metabolic acidosis if high (>26, too much base) and ph >7. 45 -- metabolic alkalosis. Step 4: check which value matches the ph.
