A practical way to reduce the exposure of pregnant women to ultrasound – listen to the baby”s heartbeat with Pinard Stethoscope, part of the midwife”s basic equipment.
Advantages:
You are hearing this baby”s heart beating with your own ears and not the ultrasound Doppler effect converted by technology back into sound. What you are hearing is direct; it is not computed or averaged by a hand-held Doppler or a CTG.
Several people do not wish any ultrasound to be used, unless there is a clear indication 3) Much more economical than other conventional alternatives.
