Systolic: The blood pressure when the heart is contracting. It is specifically the maximum arterial pressure during contraction of the left ventricle of the heart. The time at which ventricular contraction occurs is called systole.
Blood pressure is always given as these two numbers, the systolic and diastolic pressures. Both are important. Usually they are written one above or before the other, such as 120/80 mmHg. The top number is the systolic and the bottom the diastolic. When the two measurements are written down, the systolic pressure is the first or top number, and the diastolic pressure is the second or bottom number (for example, 120/80). If your blood pressure is 120/80, you say that it is "120 over 80."
The mmHg part of the measurement stands for millimeters of Mercury. This is because the original measuring devices indicated the pressure using a column of mercury. These days digital devices are used but they are calibrated to read in mmHg for consistency.

∙ 13y agoThe top number is the systolic pressure, which is the amount of pressure exerted on the walls of the arteries during the contraction and ejection of blood from the left ventricle. The bottom number is the diastolic pressure, which is the amount of pressure on the artery walls while the venticle is at rest and not contracting.

∙ 15y agoThat is the pressure the blood is at when your heart pumps. Basically it's the highest pressure your blood reaches in your body. aka: Systolic pressure

What does the 3 numbers blood pressure reading mean?
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.
When measuring blood pressure what does 180 over 90 mean?
That reading would indicate a high blood pressure, 120 over 80 would normal.
Is always ok when do blood pressure number comes out an even?
normal blood pressure reading
What is disatolic?
When measuring blood pressure, this is the lower number. It is the pressure in the heart as it rests between beats.
What does the high number of blood pressure stand for?
The larger of the two numbers in a blood pressure reading is the "systolic" reading. The lower number is the "diastolic." The systolic reading measures how hard the heart pumps when it contracts; whereas the diastolic reads the pressure when the heart relaxes.
What is the difference from systolic blood pressure and diastolic blood pressure?
Systolic (the higher number) is a reading of the pressure in your blood vessels when your heart is beating at its maximum strength. Diastolic (the lower number) tells you what the pressure is in your blood vessels when your heart is at rest.
Is 157 102 high blood pressure?
A blood pressure reading of 137/78 is not considered high. When the top number is 140 or higher that is considered high blood pressure.
What is sphygmomanometers?
It is an instrument for measuring blood pressure and especially arterial blood pressure. :)
What do the 2 numbers in blood pressure represent?
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.
How do you use a sphygmanometer?
a pressure gauge for measuring blood pressure
What is a blood pressure dinamap?
a blood pressure measuring device that largely replaced sphygmomanometers
When the ventricles are relaxed what pressure occurs and this is the lowest pressure against the walls of the blood vessels?
Diastole is the term meaning the period of ventricular relaxation with the lowest blood pressure. The diastolic number is the second or bottom number in the blood pressure reading, and it is always the lowest.
