- 3. Select the appropriate cuff size for patient’s arm. NOTE: Index line on cuff should fall within the double arrow range. If in...
- 4. Wrap cuff around arm with “artery” symbol located over the brachial artery, and with lower border about 2.5 cm above antecubital crease.
- 5. With trigger in “out” or “pump” position (see Diagram A), rapidly pump bulb to inflate cuff. Inflate to about 30 mmHg above the estimated (or palpatory) systolic pressure. NOTE: Verify the trigger is in “out” position or cuff will not inflate.
- 6. With the bell of a stethoscope (not included with this sphygmomanometer) lightly applied over the brachial artery, watch mano...
