Hi, I'm Karon Gibson, president of America Nurse. Today, we are going to be talking about the use of the stethoscope. This is something that you see used on children all the way to the elderly. And the reason is because it magnifies the sound of the heart. And this particular one has a flat diaphragm which we use with certain frequency noises in the chest. And the other one sometimes it has a bell on it which will show a different frequency. Now these are the ear pieces and as you can see they are anatomically designed to fit in the wearer's ear. They need to be cleaned after each use particularly if different people are using the stethoscope. But even if you are the only person using the stethoscope. One of the other main reasons of this stethoscope is to take a blood pressure and can measure how the heart is pumping against the arteries. And how the arteries are pumping directly against the heart. As you can see the use of the stethoscope is many. Nurse Sally was using it on Dr. Koophaus checking the carotid artery to hear the blood flowing through. Checking the heart sounds, the beats, the number of beats, the pulse and the heart beat. And also the blood pressure on his arm. As they pump it up and then listen to it coming back down again. They find out both the high and the low number to see how much pressure there's coming from the heart against the arteries. And how much the arteries are pushing back against the heart. I'm Karon Gibson, registered nurse and certified case manager. We've been talking about the many uses of the stethoscope for doctors and nurses. How they listen to your heart, listen to your blood pressure and listen to your abdominal sounds.
