How do you make spygmamometer?

A spygmamometer, commonly referred to as a sphygmomanometer, is typically made using a pressure gauge, a cuff to wrap around the arm, and a bulb for inflating the cuff. To construct one, you would attach the cuff to the pressure gauge and connect it to the inflation bulb via tubing. The cuff should be designed to fit snugly around the arm and be made of a durable, flexible material. Calibration is essential to ensure accurate readings, so the device must be tested against known pressure standards.
