11. This will occlude the brachial artery . 12. Erlanger developed and patented a new type of sphygmomanometer that could measure blood pressure from the brachial artery . 13. The higher systolic reading of the left and right arm brachial artery is generally used in the assessment. 14. First, the cuff is inflated to a point that it cuts off blood flow in the arm's brachial artery . 15. Normal blood flow in the brachial artery is 85 to 110 milliliters per minute ( mL / min ). 16. Distally, the median nerve crosses the medial side of the brachial artery and lies anterior to the elbow joint. 17. The ideal blood pressure in the brachial artery , where standard blood pressure cuffs measure pressure, is < 120 / 80 mmHg. 18. The brachial artery is closely related to the median nerve; in proximal regions, the median nerve is immediately lateral to the brachial artery. 19. The brachial artery is closely related to the median nerve; in proximal regions, the median nerve is immediately lateral to the brachial artery . 20. With a manual instrument, listening with a stethoscope to the brachial artery at the elbow, the examiner slowly releases the pressure in the cuff.
