Hello everyone! I was just helping my friend study for her CCRN and she came to me with a question about Sv02 & Po2. It stated that to be indicative of these two diseases the svo2 was 83% and the po2 was 55. she was given a list of 4 sets of values with the ones ive listed being the correct ones. I am trying to figure out how this can be. I understand that the Svo2 is the o2 bound to hgb returning to the heart and that po2 is the o2 dissolved in the blood. What i am wondering is why this is happening? Is it due to the mitochondrial disfunction that occurs cellularly at the tissues with sepsis or something else? I would appreciate some input if anyone has some. Thanks!
