There are digital and analog instruments that can measure arterial blood pressure. In many spheres of life we reckon on digital equipment. It is like we lost faith in analog measurements. In the case of the medical profession that is not always the case. Moreover, it is not the case when there is blood pressure equipment in question. You will hardly find any medical expert that prefers digital equipment over analog. The reason for that could be the fact that digital equipment is not 100 percent reliable in this case. We all know how costly mistakes can be in the medicine profession. Two instruments that are commonly being used during the measuring process are sphygmomanometer and stethoscope.
Blood measuring process
Briefly, we will try to cover how to measure blood pressure with a sphygmomanometer. We usually measure our blood pressure somewhere in the elbow area. First you should place the rubber cuff on that area. After that, be sure to place the stethoscope’s head (round end) under the cuff. Now use the squeezable bulb of the sphygmomanometer to inflate just over 180 mm Hg. Don’t worry, it is normal to feel a little discomfort in the process. The reason for that is collapsing of the major arteries. The next step is releasing the air using the air vent. That will result with the pressure drop. Do that as slowly as you can, so that your readings can be as close to accurate as they can be. The first sound you hear is the earlier mentioned systolic blood pressure. This sound will continue for some time. That is blood flowing through your arteries. After some time the sound will fade. When that happens you should take note of the value on the meter because this is your diastolic blood pressure.
