Question

Mix venous saturation is measured by  __________

(a) Ear Oximeter

(b) Intravascular Oximeter

(c) Skin Reflectance Oximeter

(d) Pulse Oximeter

I got this question during an interview.

I'm obligated to ask this question of Biotelemetry topic in section Biomedical Telemetry of Biomedical Instrumentation

Answer 1

Correct choice is (b) Intravascular Oximeter

Explanation: Mixed venous saturation varies in reflecting the changes of oxygen saturation, cardiac output, haematocrit or haemoglobin content and oxygen consumption. Intravasacular oximeters are normally used to measure mixed venous saturation, from which the status of the circulatory system can be deduced.
