Taking blood pressure manually involves using a sphygmomanometer and a stethoscope. First, wrap the cuff around the upper arm and inflate it until the pulse is no longer heard. Then, slowly release the air while listening for the Korotkoff sounds with the stethoscope. The first sound indicates the systolic pressure, and the last sound indicates the diastolic pressure. Have you ever tried using this method before, or is it something new you're exploring?
