Blood pressure is the pressure inside your blood vessels, both while the heart pumps blood and while it rests. This eMedTV article covers key aspects of blood pressure, like how blood pressure is measured and what's considered normal blood pressure.
This eMedTV article offers an in-depth look at the importance of systolic blood pressure. Systolic blood pressure (the top number in a blood pressure reading) represents the amount of pressure blood puts on vessels when the heart is beating.
Diastolic blood pressure, represented by the bottom number in a blood pressure reading, is when your heart is resting. This page of the eMedTV library explains diastolic blood pressure and offers tips for keeping it low.
Blood pressure readings consist of two blood pressure numbers written like a fraction. This page of the eMedTV archives explains what each of these blood pressure numbers mean and what is considered normal.
It's important to determine your average blood pressure reading with multiple blood pressure readings from different days. This eMedTV Web page defines "average blood pressure" and provides other blood pressure information.
The two parts of a blood pressure reading are the systolic pressure and the diastolic pressure. This page of the eMedTV library explains how a blood pressure reading measures pressure within the blood vessels while the heart beats and also at rest.
A blood pressure test measures the pressure inside your blood vessels as the heart beats and relaxes. This eMedTV resource explains how blood pressure test results are recorded as two numbers -- the systolic pressure "over" the diastolic pressure.
There are two types of sphygmomanometers used to measure blood pressure: manometric and digital. This portion of the eMedTV archives describes each sphygmomanometer type in detail and explains how a sphygmomanometer works.
