Jugular Venous Pressure is characterized by?

Jugular Venous Pressure is characterized by?

• A. Right atrial pressures and RV end diastole pressure
• B. Left atrial pressures
• C. Pulmonary capillary wedge pressure
• D. Aortic systolic pressure

Answer: (A)

Jugular venous pressure reflects the filling pressure of the right heart, mainly the right atrial pressure, which is the same as the central venous pressure. Because during diastole the tricuspid valve is open and pressures in the right atrium and right ventricle equilibrate, the right atrial pressure closely tracks the right ventricular end-diastolic pressure. That makes JVP a noninvasive window into right-sided filling pressures. It does not measure left atrial pressure—left atrial pressure is estimated by the pulmonary capillary wedge pressure—and it does not reflect systemic arterial pressure, which is the aortic systolic pressure.
