There are different tools a healthcare professional uses to measure blood pressure. Many healthcare professionals use a stethoscope and a manual sphygmomanometer to measure your blood pressure. Typically they take the reading above your elbow. The sphygmomanometer has a bladder, cuff, bulb, and a gauge. When the bulb is pumped it inflates the bladder inside the cuff, which is wrapped around your arm. This inflation will stop the blood flow in your arteries. The stethoscope is used to listen for sound of the heartbeat, and no sound indicates that there is no flow. As the pressure is released from the bladder, you will hear the sound of the blood flowing again. That point becomes systolic reading. The diastolic reading is when you hear no sound again, which means that the blood flow is back to normal. Current technology, now offers portable automatic blood pressure monitors. Some models can be battery operated, take reading from the wrist or arm, and have a memory to keep track of historical readings. Other models can include other vital sign monitoring, such as temperature, heart rate, and oximetry (the amount of oxygen in your blood). Some manufacturers of blood pressure measuring devices include, WA Baum, Mabis, Omron, American Diagnostic Corporation, and Welch Allyn.
