The Blood Pressure Calculator calculates the blood pressure based on your systolic and diastolic pressure. The contraction of the heart takes place when the heart beats. This results in pushing of the blood through the arteries to all the parts of the body. A pressure on the arteries is created due to this force and this is termed as systolic blood pressure.
The diastolic blood pressure is specifically the minimum arterial pressure during relaxation and dilatation of the ventricles of the heart when the ventricles fill with blood.
The heart goes through two phases to complete one cycle which is called a cardiac cycle. The two phases are the diastole phase where the heart ventricles relax and the heart is filled with blood and another is a systole phase where the contraction of ventricles take place and the blood is pumped out of the heart. The average pressure which arteries confront in the course of one cardiac cycle is rightfully termed as Mean Arterial Pressure or MAP. It is said that MAP values gauge the perfusion to the crucial organs to the body better than the systolic blood pressure (SBP). The MAP values are evaluated by thorough invasive monitoring and intricate estimations. In order to get accurate figures, systolic blood pressure and diastolic blood pressure readings are utilized for MAP calculations.
The MAP ranges are classified into the following levels:
Pulse Pressure (PP) is the numeric difference between your systolic and diastolic blood pressure readings. It is measured in millimeters of mercury (mmHg). It represents the force that the heart generates each time it contracts. In adults older than age 60, especially in men, a pulse pressure greater than 60 can be a predictor of heart attacks or other cardiovascular disease. In some cases a low pulse pressure of less than 40 indicates poor heart function. A higher pulse pressure of greater than 60 may reflect leakage in the heart valves, often due to age-related losses in aortic elasticity.
