1
Q

Dependent edema

A

abnormal accumulation of fluid in extracellular spaces of body; generally legs

2
Q

external jugular vein

A

begins near the angle of the mandible, inferior to the lobe of the auricle, crossing the sternocleidomastoid muscle

if venous pressure is raised, vein becomes prominent

distension –> heart failure, obstruction of the superior vena cava, enlarged supraclavicular nodes, or increased intrathoracic pressure

3
Q

internal jugular vein, examined for 2 components

A
  1. jugular venous pulsations

2. jugular venous pressure

4
Q

a wave

A

Increase in right atrial pressure produced by right atrial contraction

5
Q

x descent

A

Decrease in right atrial pressure caused by atrial relaxation

6
Q

v wave

A

Increase in right atrial pressure due to its filling with blood from the IVC during ventricular systole (tricuspid valve is closed)- coincides with carotid pulse

7
Q

y descent

A

Decrease in right atrial pressure due to opening of the tricuspid valve at end of ventricular systole
