Checking Blood Pressure

Not to long ago we played with the stethoscope and blood pressure readings. We tried this for the first time with a partner to check their blood pressure and how it works. I did have a little bit of a hard time to try and figure out how to use the "old" fashion pumps.. but I finally figured it out! I had to learn about a lub and a dub of the heart beat... we have two beats for the heart. The first beat is called the "Lub" and the second one is called the "Dub." So when you put this together the heart beat is called the Lub Dub. In order to get a reading, you had to pump it til you got 160. This was a little bit confusing for me at first, but after a couple of tries, I got the hang of it!! (:
