Web Privacy Policy less perfusion, but also less ventilation=better ratio give body time to recognize and open up alveoli. Perfusion refers to the flow of blood through the vessels of the body, on its way to the capillary beds in various tissues which receive bloodflow. Perfusion is a procedure that uses a cardiopulmonary bypass machine, also called a heart-lung machine, to maintain a patient's normal heart and lung functions while surgical procedures, like open-heart surgery, are conducted. Capillary refill time (CRT) is defined as the time taken for color to return to an external capillary bed after pressure is applied to cause blanching. Frequently, cardiac and thoracic surgeries are dependent upon still, unventilated lungs and a motionless heart, as a necessary component of vital surgery.
