DOPPLER
Doppler ultrasonography is a device
that use sound waves to be able to know the blood flow in the blood. If you use
doppler it will sound fetal heart beat.
How you use it ?
1. Plug the battery in doppler
2. Turn on the doppler by pressing the on or off button (usually on the side)
3. Adjust the volume so you can hear a hiss like wind or radio without a channel
4. Apply a special gel to your stomach
5. Attach the doppler fetal probe and look for the most clear and loud sound
6. Caculate the fetal heart sound for one minutes
My opinion about doppler is
amazing, because with doppler we can listen to fetal heart beat. And then,
doppler is also very practical beacuse of it is small size and easy to use.
