1.	What is used to measure mix venous saturation?(a) Ear Oximeter(b) Pulse Oximeter(c) Skin Reflectance Oximeter(d) Intravascular OximeterI have been asked this question at a job interview.This interesting question is from Biofeedback Instrumentation in portion Biomedical Recorders of Biomedical Instrumentation
Answer» RIGHT answer is (d) Intravascular Oximeter For explanation I would say: Intravasacular oximeters are normally used to measure mixed venous saturation, from which the status of the CIRCULATORY system can be deduced. Mixed venous saturation varies in REFLECTING the changes of oxygen saturation, CARDIAC output, haematocrit or haemoglobin content and oxygen consumption.
