  4. y
  5. v

 

2

what causes the a wave?

Atrial contraction

(a for Atria)

3

what causes the c wave

early ventricuar contraction

it's from the elevation of the tricuspid valve

(c- for Contraction)

4

what causes the v wave?

venous return against a closed tricuspid valve

(v for Venous return)

5

what may cause a large A-wave

anything that increases the pressure of right atrium during contraction

  • tricuspid stenosis
  • Pulmonic stenois
  • Pulmonary HTn
  • decreased right ventricular compliance

6

what can cause a Large V-wave

anything that causes extra filling (fluid) in right atrium

  • tricuspid regurg
  • right ventricle failure
  • Constrictive pericarditis
  • Cardiac tamponade

7

why would you use a cvp monitoring

Assess pts fluid status/ blood volume

 

8
