Why is niggardly arterial pressure substantial?
Answers:
It tell you the pressure of blood hitting against arterial walls.
If the pressure is really big, someone may be at risk for blowing a blood vessels, which can be life threatening.
Probably because arteries have like mad of pressure within their walls from the heart's work. Too much pressure makes a rupture more likely to take place, and is generally unhealthy. Not enough pressure (only within severe cases) means the heart is weak.
Mean Arterial Pressure (MAP) is the mean pressure on your arteries. As a rule of thumb, it can be described as diastolic pressure + 1/3 PP (systolic pressure-diastolic pressure) since the contraction phase constitues 1/3 of the time.
The blood pressure is important to transport the blood to different organs. During surgery, the sugeon keeps track on the MAP to ensure blood flow to exalted organs (brain, liver, kidneys etc). A pulse pressure over 60 mmHg is enough to sustain the organs of an average person.
The blood pressure depends on cardiac output (a strong heart leads to a big cardiac output) and total peripheral resistance (artherosclerosis and stress increases the resistance). A high pressure leads to difficult stresses of the arterial wall and increase the risk of thrombosis, embolism and rupture. A high blood pressure is also an indication that the vessles are unhealthy.
