The pulsus paradoxus that occurs as a result of pericardial effusion is significant because it reflects the impairment of the:
A)diastolic filling pressures of the right ventricle and reduction of blood volume in both ventricles.
B)blood ejected from the right atria and reduction of blood volume in the right ventricle.
C)blood ejected from the left atria and reduction of blood volume in the left ventricle.
D)diastolic filling pressures of the left ventricle and reduction of blood volume in all four heart chambers.

Quizplus · Accepted Answer

Pulsus paradoxus means that the arterial blood pressure during expiration exceeds arterial pressure during inspiration by more than 10 mmHg. This clinical finding reflects impairment of diastolic filling of the left ventricle plus reduction of blood volume within all four cardiac chambers.
