Incidentally, Ultrasound also allows you to see the first images of the small in your belly and even know the sex of the baby.
An ultrasound is performed
According to www.internetdict.com, an ultrasound uses high frequency sound waves to study structures and movements in the inside of your body. The science behind this technology is similar to the sonar of a submarine or a bat: a transducer emits inaudible sound waves and form images from eco receives when the waves bounce off with the tissues of your body and the baby. Ultrasound has the advantage that produces images in real time, and can also capture subtle movements, as the blood flow to your small or the beating of your heart.
The procedure is simple, non-invasive and painless. A specialist is done and can last between 30 and 60 minutes. These are the steps:
- You lay on a stretcher. The only part of your body that you should expose is your belly, which is easier if you use two-piece outfit.
- Apply you a gel on the skin of your belly to help the transmission of sound waves. The gel may be cold, but does not cause you more discomfort. Also gel is applied to the transducer, which is the part of the device which come into contact with your skin.
- The transducer is placed on your tummy and moves through the area to examine.
- As your physician move the transducer you can go see an on-screen shapes. At the beginning can be difficult to identify what you see. Depending on the stage of pregnancy that you make yourself the ultrasound, and with a little guidance, you can note the different parts of your little body: head, trunk, and extremities. Your doctor can tell you the location of different organs, including his heart, and his facial features. You can also see the movements of your baby in the womb. While you enjoy this technological event with your little, your doctor take your body measurements, listen to your heartbeat, evaluates the function of its organs, analyzes their anatomy and other aspects that indicate the well-being of your baby.
- At the end of the ultrasound your doctor carries out a report and perhaps print out pictures of your little or give you a video of the encounter.
In the very early stages of pregnancy, when your baby is still not visible through the tummy, you can require a vaginal ultrasound. In this case the transducer has a long and narrow shape. After the application of a protector, transducer introduced through the vagina. This type of ultrasound is performed only when it is medically necessary.
