What does 'Blood Pressure' mean?

Find out what Blood Pressure means. Blood Pressure is explained by Margaret McMillion - author of PERSONAL BAGGAGE

Blood Pressure

Blood pressure is the force exerted by circulating blood upon the walls of arteries in our bodies. Systolic blood pressure, the first sound heard through a sphygmomanometer when the blood pressure cuff is released, is the pressure exerted when the heart pumps and pushes blood into the circulatory system. Diastolic pressure, noted when the thump of the heart is no longer heard, is the continuing force exerted upon the walls of arteries when the heart is at rest. Normally this is below 80. A diastolic pressure of 90 or higher is considered high blood pressure and requires a doctor’s attention. Systolic blood pressure is affected by anxiety and may vary more than diastolic, but a systolic reading of 140 or higher means you have high blood pressure and are at risk of developing heart disease.

Your body’s blood pressure and fluid balance is regulated by a hormone system triggered when your kidneys and brain detect low blood pressure in their arteries. This hormone system, called the Rennin-Angiotensin System, causes blood vessels to constrict and kidneys to save water, thereby increasing blood volume and blood pressure. Some medications for high blood pressure are aimed at controlling this system.

High blood pressure (hypertension) is largely a symptomless condition and has been called “The Silent Killer.” You may experience nervousness, sweating, facial flushing, or insomnia, but nose bleed and headache are more common in a hypertensive crisis (a medical emergency) when blood pressure reaches 180/110.

Food changes that may be beneficial to a hypertensive patient include limiting salt intake (sodium increases blood volume), drinking skim milk or 1% milk (calcium and Vitamin D together help to reduce blood pressure), and consuming heart-healthy foods full of potassium, folic acid, magnesium and soluble fiber--like spinach, beans (navy, lima, soy, pinto, and kidney), white potatoes, bananas, and dark chocolate.

Chronic low blood pressure that causes no noticeable symptoms (such as dizziness, fainting, blurred vision, nausea, clammy skin, rapid, shallow breathing, or fatigue) is not a cause for concern. But if you experience these symptoms and your blood pressure is normally higher, you must seek medical help because severely low blood pressure can deprive vital organs of oxygen and nutrients.

In Chapter 3 of PERSONAL BAGGAGE, when CCU patient Darryl Dodson (with a diagnosis of rule out heart attack) became symptomatic with low blood pressure, it was because death of heart tissue had caused rupture of the papillary muscle controlling his heart’s mitral valve and the valve was not closing properly when his heart squeezed blood out into his arteries. Blood was leaking back into the left side of his heart (mitral regurgitation) resulting in low cardiac output and decreased blood pressure.
