Improvement of a Mathematical Model to Predict CO2 Removal in Hollow Fiber Membrane Oxygenators

open access: yesBioengineering, 2022
The use of extracorporeal oxygenation and CO2 removal has gained clinical validity and popularity in recent years. These systems are composed of a pump to drive blood flow through the circuit and a hollow fiber membrane bundle through which gas exchange ...

Basics of cardiopulmonary bypass

open access: yesIndian Journal of Anaesthesia, 2017
Cardiopulmonary bypass (CPB) provides a bloodless field for cardiac surgery. It incorporates an extracorporeal circuit to provide physiological support in which venous blood is drained to a reservoir, oxygenated and sent back to the body using a pump ...
