How to use a sphygmomanometer correctly
Put the cuff on your left arm 2-3 cm (~1 inch) above your elbow. Cuff's tubes should run along the center of your arm. Wrap the cuff around your arm so that you can fit one finger between the cuff and your arm, and attach it with Velcro.
Put the stethoscope (you will need to obtain one separately) on and place the head on your humeral artery a bit above the elbow joint facing the body where the artery usually runs. You can secure the stethoscope using the cuff.
