The first number in a blood pressure reading is the systolic blood pressure. It represents the pressure in the artery when the heart is contracting. The second number is the diastolic blood pressure, and represents the pressure when the heart is relaxing.
When a blood vessel (like an elastic pipe) is empty there is no pressure on its wall. When there is blood flowing in a blood vessel it exerts pressure on the walls of the blood vessel (pipe). This is the basal pressure called the Diastolic pressure (The lower of the two numbers). When the heart pumps blood it drives the blood with force and this exerts higher pressure on the walls of the blood vessel. This is called the Systolic pressure, the higher number in the blood pressure measurement. Thus, Blood Pressure of 120/70 means the systolic pressure is 120 and the diastolic pressure is 70.
The blood pressure is the pressure in the arteries created by the large quantity of blood circulating in them. The number on the top is the systolic blood pressure and the number on the bottom is the diastolic blood pressure. The systolic BP is the pressure in the arteries right when the blood is pumped out of the heart, therefore the pressure is bigger. The diastolic BP is the pressure in the arteries after the blood has been pumped out and before the next heart contraction. At this moment, the heart is relaxed and the pressure is much lower.
The upper reading is the systolic blood pressure while the lower reading is the diastolic blood pressure. Systole is the contraction of the heart while diastole is the relaxation of the heart.
Systolic pressure is the upper number and diastolic pressure is the lower number.
The upper Blood Pressure Number is the Systolic, Which is the force of blood in your arteries when you heart beats.
systolic pressure when ventricals are contracting while during diastole they are in relaxed state
normal blood pressure reading
He's blood pressure has to reach to 200.
systolic, its the number on top, that's why that number is larger
Resting Blood Pressure: Diastolic (blood filling into atrium of heart) is the top number Systolic (blood pumping from atrium into ventricles of heart) is the bottom number
It is the diastolic pressure. It is the pressure on the walls of the arteries when the heart is resting.
