A cardiovascular perfusionist, clinical perfusionist or perfusiologist, and occasionally a cardiopulmonary bypass doctor or clinical perfusion scientist, is a healthcare professional who operates the cardiopulmonary bypass machine (heart–lung machine) during cardiac surgery and other surgeries that require cardiopulmonary bypass to manage the patient's physiological status. As a member of the cardiovascular surgical team, the perfusionist also known as the clinical per… Web27 jun. 2016 · Perfusion was initially developed in the late 1980s as a means for increasing protein titers (1). However, high costs driven by media consumption limited widespread commercial adoption. In the same time frame, advances in cell line engineering, media composition, and bioreactor design led to 10-fold increases in titers for batch and fed …

"WebPulse oximetry is a test used to measure the oxygen level (oxygen saturation) of the blood. It is an easy, painless measure of how well oxygen is being sent to parts of your body furthest from your heart, such as the arms and legs. A clip-like device called a probe is placed on a body part, such as a finger or ear lobe. " - How would you define perfusion
