Right atrial pressures are obtained in order to assess?

Expert Solution

Right atrial pressures are obtained inorder to assess

the stretch of the right ventricle, which in turn determines the output of the heart, which in turn determines the outputs of the left heart. The output of the left heart is the cardiac output

Right atrial pressure is the blood pressure in the right atrium of the heart . RAP is often nearly identical to central venous pressure , although the two terms are not identical, as a pressure differential can sometimes exist between the venae cavae and the right atrium

Factors affecting RAP

Factors that increase RAP include

Hypervolemia
Forced exhalation
Tension pneumothorax
Heart failure
Pleural effusion
Decreased cardiac output
Cardiac tamponade
Mechanical ventilation and the application of positive end expiratory pressure
Pulmonary hypertension
Pulmonary embolism

Factors that decrease RAP include

Hypovolemia
Deep inhalation
Distributive shock
