ABG FINAL EXAM SOLVED COMPLETE QUESTIONS AND CORRECT DETAILED ANSWERS (VERIFIED ANSWERS) 1. What does the steep part of the oxy Hb curve represent? - ANSWER between 10 and 60mmHg- this is where O2 will rapidly bind with Hb 2. What factors affect the oxy Hb diss. Curve? - ANSWER changes with temp, CO2, 23DPG and PH. 3. A decreased affinity means? - ANSWER A left shift- temp, 23 dpg or CO2 decreases, this leads to an increase in PH 4. How does a decrease or increase in...
