Systolic
Blood is under its greatest pressure in the arteries, specifically in the aorta, which is the largest artery in the body. This high pressure occurs during systole, when the heart contracts and pumps blood into the aorta. As blood moves through the circulatory system, pressure decreases in smaller arteries and arterioles, ultimately reaching its lowest point in the veins.
you can determine the maximum inflation point when taking blood pressure by using palpation.
When the blood pressure cuff is inflated, the blood flow is stopped. Slowly the cuff is decreased. When the technician starts to hear the blood flow, these are called Korotkoff Sounds. This pressure point defines the systolic pressure.
Diastolic blood pressure is recorded at the point when the sounds of the Korotkoff phases, which are heard through a stethoscope, disappear or are no longer audible. This indicates the pressure in the arteries when the heart is at rest between beats. Typically, this is noted as the second number in a blood pressure reading, following the systolic measurement.
Because blood is liquid, its boiling point is affected by pressure changes. Extremely low pressure would lower the boiling point enough that the blood would boil at a temperature less than body temperature.
The highest pressure in any open vessel is at the deepest point.
Fluid pressure is the greatest at the deepest point. If the fluid is in different shaped vessels, the pressure is the greatest at the bottom of the vessel no matter what the shape.
A pressure point is called so because it refers to specific areas on the body that are believed to be sensitive to applied pressure. Stimulating these points is thought to help manage pain, promote relaxation, or alleviate tension in the body.
The peak of a wave where the greatest air pressure occurs is known as the crest. This is the highest point of the wave where the air particles are most compressed, resulting in an increase in air pressure.
A pressure gauge is called a gauge because it typically measures pressure relative to atmospheric pressure, which is often considered as the reference point or zero point for pressure measurements. On the other hand, a meter usually measures absolute values without reference to a specific point.
The point of elevating the feet and lowering the head is not to raise blood pressure, but to use gravity to cause an increased flow of blood to the brain.
Edema, or Oedema, can be caused by Blood Plasma seeping from Blood vessels into adjoining tissue, as a result of a weak point in a Blood vessel. The primary risk is that this seepage point, is the most likely point of a rupture, or Aneurysm.
