Question

Ultrasound provides basically clearer signal than does phonocardiography.

(a) True

(b) False

I have been asked this question in homework.

My doubt is from Recording System topic in section Foetal Monitoring Instruments of Biomedical Instrumentation

Answer 1

The correct option is (b) False

The explanation is: False, Phonocardiography provides a basically cleaner signal than does ultrasound, thus allowing a greater chance of detecting a smooth baseline FHR. Unfortunately, phonocardiography is more susceptible to artefacts introduced from ambient noise, patient movement or other intra-abdominal sounds.
