A concentration degree vs a regular degree. #1. Alkayus. A concentration degree vs a regular degree. Good afternoon everyone. I'm new here and it's great to be here. I have a very large interest in Physics and plan on getting a degree in said field.

A sphygmomanometer is the older kind of equipment that measures blood pressure using a column of mercury. The person taking your blood pressure will put a cuff around the top of your arm, pump up this cuff and then listen for sounds through a stethoscope placed on your arm.
There are two types of sphygmomanometers: ' 1  require a stethoscope for auscultation (see below). 2  They are used by trained practitioners. 3  It is possible to obtain a basic reading through palpation alone, but this only yields the systolic pressure.4  Mercury sphygmomanometers are considered to be the gold standard. Aneroid sphygmomanometers (mechanical types with a dial) are in common use; they may require calibration checks, unlike mercury manometers. 2  Aneroid sphygmomanometers are considered safer than mercury based, although inexpensive ones are less accurate. 3  A major cause of departure from calibration is mechanical jarring.
