Question

4. Given: Fio2 0.21, Pb-747 mm Hg, Paco2-50 mm Hg, Pao2 54 mm Hg, R 0.80 Fio2 1.0, Pb-747 mm Hg, Paco2 50 mm Hg, Pao2 548 mm Hg Find: PAO2 mm Hg (on room air) mm Hg (on room air) A-aDO2 Is the A-aDo2 normal (on room air)? Was the response to oxygen therapy normal? What was the major cause of hypoxemia?

Answer 1

P_A_O_2 = 5 times 40 = 200 MM Hg The normal patient the measured Pa_O_2 should equal to 5 times Fi_O_2 (2) A-aDO_2 = alveolar P_O_2, 760 MM Hg at real level (3) on room air (F_iO_2 = 0.21,] (4) Normal levels of arteria blood oxygen one between 75 and 100 MM Hg An oxygen level of 60 MM Hg (or) lower indicates. (5) cause of hypoxima: * * strong pain medicines and drug that hold back breathing * Heart problems * Anemia (a low number of red blood cells. which any oxygen
