6.2 Applying the Arm Cuff
- Ensure the cuff is placed directly on your bare skin or over thin clothing (less than 5mm thick).
- Slide the cuff onto your left upper arm, with the air tube pointing towards your forearm.
- Position the cuff so its lower edge is about 1-2 cm above your elbow joint.
- Wrap the cuff snugly around your arm, ensuring two fingers can fit comfortably between the cuff and your arm. The center of the cuff should be at the same height as your heart.
