Abstract

physiologic changes introduced by cardiopulmonary bypass include an alteration in pulsatile, blood flow >pattern, exposure of blood to nonphysiologic surface, blood damage due to shear stress, hemodilution, and overload stress response. The increase of cardiopulmonary bypass safety depends on good knowledge and understanding on normal circulatory hemostatis changes. Circulation control during cardiopulmonary bypass was done by observing systemic blood flow, arterial pressure, venous pressure, and blood< flow distribution. Circulatory changes during cardiopulmonary bypass can happen on set of action, hipotermia periode, rewarming phase, during cardiopulmonary bypass with warm temperature, and also cardiopulmonary bypass can cause changes in microsirculation and adequacy of tissue perfusion.
