Blood Pressure
Vascular pressure, or blood pressure as it is more commonly referred to, is a vital indicator of health and fitness in all people and is determined by calculating how much force is placed on the walls of blood vessels by circulating blood. On the other hand, arterial pressure is the type that indicates the level of pressure as blood traverses the arteries, arterioles, capillaries and veins and is the term most often associated with blood pressure; moreover, arterial pressure decreases as the bloods travels farther away from the heart.
Arterial pressure is most commonly measured via a sphygmomanometer, which uses the height of a column of mercury to reflect the circulating pressure (see Non-invasive measurement). While most modern blood pressure devices no longer contain mercury, pressure level values continue to be reported in millimeters of mercury, or mmHg. The systolic arterial pressure is defined as the peak pressure in the arteries, which occurs near the beginning of the cardiac cycle; the diastolic arterial pressure is the lowest pressure (at the resting phase of the cardiac cycle). When considering the total overall pressure of blood flow throughout the cardiac cycle, the measurement is reported as the mean arterial pressure. Moreover, pulse pressure indicates the variance of maximum and minimum pressure levels.
For a healthy adult in a rested state, normal blood pressure levels are 120 mmHg (16 kPa) for the systolic reading and 80 mmHg (11kPa) for the diastolic pressure. This is normally written as 120/80 mmHg and is spoken as “one hundred twenty over eighty”. Although the 120/80 mmHg is a common benchmark, normal readings vary widely depending on the health and overall fitness of the individual. Arterial blood pressure is not constant and changes frequently based on many different factors and undergoes fluctuations that are both natural and to be expected. In fact, blood pressure levels can vary as frequently as one heart beat to the next.Things that cause blood pressure levels to rise and fall are: stress, nutrition, drugs or alcohol and disease.
Hypertension refers to arterial pressure being abnormally high, as opposed to hypotension, when it is abnormally low. The only basic health test performed more than a blood pressure check is the measuring of the body’s temperature with a thermometer.
Your good health should be your most prized asset and if you have a blood pressure concern, research all the information you can find. Seeking professional advice is essential and have a chat with your doctor about your blood pressure concerns. Balance up what you’ve learned and work on maintaining a healthy blood pressure level and maintaining good health.
For the most thorough and up to date information on blood pressure levels, arterial pressure monitoring and other useful information, use reliable specialist sites dealing with blood pressure issues.
