Here is a step-by-step tutorial on how to read your blood pressure:

1. Sit down and relax for 5 minutes before taking your blood pressure.
2. Wrap the cuff around your upper arm and make sure it's snug but not too tight.
3. Place the stethoscope earpieces in your ears.
4. Use the bulb to inflate the cuff until it's tight around your arm.
5. Slowly release the air from the cuff while listening with the stethoscope.
6. Note the reading on the gauge when you first hear a sound (systolic pressure) and when you no longer hear a sound (diastolic pressure).
7. Record your blood pressure reading.
