What is the term used for the force exerted by the blood against the blood vessel walls?

What is the term used for the force exerted by the blood against the blood vessel walls?

Blood pressure is the force of the blood pushing against the artery walls. The force is made with each heartbeat as blood is pumped from the heart into the blood vessels. This is called systolic blood pressure.

What is the expansion and recoil of an artery called?

Pulse is defined as the alternate expansion and recoil of an artery. With each heartbeat, blood is forced into the arteries causing them to dilate (expand). Then the arteries contract (recoil) as the blood moves further along in the circulatory system.

What is the name for pressure exerted by blood on the arterial walls during ventricular contraction?

The systolic pressure is the higher value (typically around 120 mm Hg) and reflects the arterial pressure resulting from the ejection of blood during ventricular contraction, or systole.

Which korotkoff sound represents the diastolic blood pressure in an adolescent?

Among infants and children ages 3–12 years, the fourth Korotkoff sound was used to signify diastolic BP, while in adolescents (13–18 years), both fourth and fifth Korotkoff sounds were used as markers of diastolic BP. At birth, the average systolic and diastolic pressures were 70 mmHg and 50 mmHg, respectively.

What happens during the systolic reading of the artery?

When the heart pushes blood around the body during systole, the pressure placed on the vessels increases. This is called systolic pressure. When the heart relaxes between beats and refills with blood, the blood pressure drops. This is called diastolic pressure.

Why does blood exert a pressure on the walls of the blood vessels?

There are two pressures measured: (1) the systolic pressure (the higher pressure and the first number recorded), which is the force that blood exerts on the artery walls as the heart contracts to pump the blood to the peripheral organs and tissues, and (2) the diastolic pressure (the lower pressure and the second …

When listening to heart sounds auscultation the first sound heard is referred to as LUBB this sound is produced by?

The first heart sound, called S1, makes a “lub” sound caused by the closure of the mitral and tricuspid valves as ventricular systole begins.

What is vessel recoil?

Introduction. Elastic recoil refers to a rebound of the vessel wall after undergoing percutaneous transluminal angioplasty ( PTA ) that results in recurrent narrowing (1,2).

When recording blood pressure the pressure is written over the?

Blood pressure is recorded as two numbers, the systolic pressure (the pressure when the heart beats) over the diastolic pressure (the pressure when the heart relaxes between beats). We record this with the systolic pressure first (on the top) and the diastolic pressure second (below).

What is the sound of systolic and diastolic?

Traditionally, the systolic blood pressure is taken to be the pressure at which the first Korotkoff sound is first heard and the diastolic blood pressure is the pressure at which the fourth Korotkoff sound is just barely audible.

How do you hear systolic and diastolic blood pressure?

Open the valve slightly. Deflate the cuff slowly and evenly (OER #1) at about 2 mm Hg per second. Note the points at which you hear the first Korotkoff sound (systolic blood pressure) (OER #1) and the point in which the Korotkoff sounds go silent (diastolic blood pressure) (Hypertension Canada, 2020).

What does systolic reading indicate?

Systolic blood pressure, the top number, measures the force your heart exerts on the walls of your arteries each time it beats. Diastolic blood pressure, the bottom number, measures the force your heart exerts on the walls of your arteries in between beats.
