Pathophysiology Exam 2 Study Guides Chapter 12- HIV/AIDS o Patient Progression to AIDs book pg 432 o What immune disorder is associated with HIV AIDS o The Difference Between HPV1 and HPV2 o How is HIV transmitted? Chapter 13- Alteration in O2 Transport o Understand the relationship between oxygen and hemoglobin Oxygen binds to hemoglobin Oxygen-hemoglobin dissociation curve Y-axis=% O2 saturation- amount of hemoglobin bound to O2 X-axis= partial pressure of O2 How to read curve. (right to left) the plateau is around PP 104% mm hg and 98% O2 sat (atrial blood). When gas is exchanged to the lungs, the venous blood (VB) has a PP is 40% mm Hg and the O2 stat (hemoglobin saturation) is 75% specifically for the venous blood (systemic/peripheral venous). o As hemoglobin drops off O2, CO2 binds to hemoglobin. Right before it drops off O2= 98%. After draining= 75% o 98% O2 Sat of hemoglobin in the atrial blood- 75% O2 Sat of venous blood= 23% amount of O2 unloaded to tissue cells
