{"content":[{"text":"What is Central Blood Pressure? \n Central Blood Pressure is the pressure in the ascending aorta, just outside the left \n ventricle. It is the pressure that the target organs are exposed to and, due to arterial \n pressure amplification, is lower than brachial cuff pressures.","bbox":{"left":0.091212,"top":0.154177,"width":0.820976,"height":0.10137399999999996}},{"text":"Blood pressure is not a constant force throughout the body. Numerous factors such \n as arterial stiffness affect the pressure wave as it travels from the aorta to the arm, \n making cuff pressure an unreliable indication of central pressure. As you age, your \n arteries stiffen and amplification is reduced.","bbox":{"left":0.091212,"top":0.265278,"width":0.827651,"height":0.07605699999999999}},{"text":"Amplification of blood pressure wave \n Age 24","bbox":{"left":0.39019,"top":0.354701,"width":0.335482,"height":0.037408}},{"text":"Age 68","bbox":{"left":0.505006,"top":0.434139,"width":0.06333699999999998,"height":0.01541999999999999}},{"text":"Aorta","bbox":{"left":0.132188,"top":0.476325,"width":0.04983400000000002,"height":0.01541999999999999}},{"text":"Renal Artery","bbox":{"left":0.338455,"top":0.476325,"width":0.110288,"height":0.01541999999999999}},{"text":"Iliac Artery","bbox":{"left":0.581794,"top":0.476325,"width":0.09688299999999994,"height":0.01541999999999999}},{"text":"Brachial Artery","bbox":{"left":0.800282,"top":0.476325,"width":0.13275999999999988,"height":0.01541999999999999}},{"text":"Central Blood Pressure Variation: Systolic blood pressure is amplified by a level that \n varies greatly from patient to patient.
