You may have your blood pressure taken with a digital machine or with a sphygmomanometer.
Here we show a digital machine that may be used to measure your blood pressure.
The digital machine consists of a cuff attached by a tube to a digital measuring device.
These are more commonly used than sphygmomanometers. Here we see blood pressure being taken using
a digital machine. The cuff will be wrapped around the top of
your arm and fastened with Velcro. Your nurse or doctor will press a button on
the machine to inflate the cuff. When the cuff is fully inflated and as it
automatically deflates, a sensor in the cuff detects your pulse and converts this information
into a measurement of blood pressure. This is displayed on the screen.
You may have your blood pressure taken with a sphygmomanometer.
Here we show a sphygmomanometer. This has a cuff with two tubes coming off
it. One of these tubes is attached to a hand pump
and the other is connected to a column of mercury.
Here we see blood pressure being taken using a sphygmomanometer.
The cuff will be wrapped around the top of your arm and fastened with fastened with Velcro.
Your doctor or nurse will inflate the cuff using the hand pump.
When the cuff is inflated, your nurse or doctor will listen to the sounds of your pulse using
a stethoscope placed on your arm below the cuff.
Your nurse or doctor will measure your blood pressure by taking two readings from the column
of mercury while listening to your pulse. This is the end of the animation. Click on
