Arterial Blood Pressure – How to Avoid Being a Victim of High Blood Pressure

Whenever your left ventricle sends blood into your aorta, your aortic pressure tends to rise. The highest aortic pressure that occurs after this ejection would be known as systolic pressure. As your left ventricle refills as it relaxes, your aorta’s pressure tends to drop. This low aorta pressure that happens prior to your ventricle sending blood into your aorta is known as diastolic pressure.

Whenever you blood pressure gets measured with a sphygmomanometer, you can see the systolic pressure as the value on top and the diastolic pressure as the value on the bottom. Regular systolic pressure stands at 120 mmHg at most, while regular diastolic pressure stands at 80 mmHg at most. The overall difference in-between the diastolic and systolic pressures would be known as arterial blood pressure. This usually stays within the range of 40 and 50. The regular arterial blood pressure would be the regular pressure at each arterial pulse cycle.

Whenever your arterial blood pressure gets measured with a sphygmomanometer on your upper arm, the measured diastolic and systolic pressures show the pressures in your brachial artery. This is a bit different compared to the pressure that can be located within the aorta. While your aortic pressure pulse goes through your aorta and into your distributing arteries, characteristic changes happen within the diastolic and systolic pressures. Your systolic pressure will rise, while your diastolic pressure will drop, so your pulse pressure will rise while your pressure pulse moves farther away from your aorta. This happens due to the vessel branching’s reflective waves and decreased arterial compliance while your pressure pulse goes through your aorta to your systemic arteries.
