Blood Pressure and Heart rate

Lub

atrioventricular valves open

Dub

Semilunar valves close

Blood Pressure

three factors that determine it: Blood volume, Total peripheral resistance, Cardiac Output

Mitral Regurgitation

heart murmur

Mitral Stenosis

wooshing like sound

Vasodilation

Vessel diameter increases, BP decreases

Vasoconstriction

Vessel diameter decreases, BP increases

Angioplasty

A medical procedure that restores blood flow through the artery by expanding it using a balloon.

Hypertension

causing restricted blood flow and potentially leading to increased blood pressure or ischemia. 140 or above/90 or above

Radial Artery

Location of heart rate

Brachial Artery

Manual blood pressue

Systole

left ventricle contracts

Diastole

left ventricle relaxesand fills with blood for the next heartbeat.

Laminar flow

is the smooth, orderly flow of fluid in layers, where each layer moves parallel to the walls of the vessel. No sound.

Turbulent Flow

is an irregular, chaotic flow of fluid that occurs when the flow velocity exceeds a critical threshold, often resulting in audible sounds.

Map = [(2x Diastolic) + Systolic]/3

Mean Arterial Pressure (mmHg)

CO= HR x SV

Cardiac Output (L/min)

Heart rate

HR is beats/minutes

SV=1.75(systolic pressure-diastolic pressure)

Stroke Volume

PP=sys bp-dia bp (mmHg)

Pulse Pressure
