Question

The narrow beam transducer is very sensitive and produces a good trigger signal for instantaneous heart rate determination.

(a) True

(b) False

This question was posed to me in an interview for internship.

My doubt stems from Oximeters topic in section Oximeters of Biomedical Instrumentation

Answer 1

Correct choice is (a) True

To elaborate: True, The narrow beam transducer is very sensitive and produces a good trigger signal for instantaneous heart rate determination because it takes time to detect a good signal and, therefore, frequent transducer repositioning is necessary.
