If you have heart disease or high blood pressure, it's a good idea to have both a stethoscope and a blood pressure cuff (sphygmomanometer) to monitor your blood pressure regularly.Purchase a flat diaphragm-model stethoscope rather than a bell-shaped one. The flat surface makes it easier for you to hear.
Blood pressure cuffs come in many models. If you have difficulty reading the gauge on a regular cuff, look for a model that uses an upright mercury column, or an electronic digital model. Ask your pharmacist to recommend a blood pressure kit and show you how to use it.
