Question

The narrow beam transducer permits the operator to position the baseline on the zero-level line of recording chart.

(a) True

(b) False

I have been asked this question in my homework.

The query is from Ear Oximeter in section Oximeters of Biomedical Instrumentation

Answer 1

The correct choice is (b) False

The best I can explain: False, the labour-activity transducers are pressure transducers that drive circuits for obtaining an electrical indication of pressure by conventional means. The pressure channel on the recorder is provided with a positioning control. This is done because the baseline is affected by the static pressure on the transducer that results from the tension on the belt holding the transducer in place. The control permits the operator to position the baseline on the zero-level line of the recording chart.
