Question

The toco-transducers are temperature sensitive.

(a) True

(b) False

I had been asked this question in an online quiz.

This interesting question is from Ear Oximeter in section Oximeters of Biomedical Instrumentation

Answer 1

Right option is (b) False

To elaborate: False, the toco-transducers are location sensitive. They should be placed over the fundus where there is maximum motion with the contractions. The toco-tonometer transducer cannot be used in the same place as the foetal heart rate detector, thus the patient must have two transducers on her abdomen.
