文摘
- •
Continuous supervision of extracorporeal O2 and CO2 gas transfer rates is proposed.
- •
Only non-invasive sensors (e.g. in gas phase) are used (no blood gas analysis).
- •
An extended Kalman filter for estimating O2 transfer rate is proposed.
- •
Accuracy and performance were evaluated using in silico and in vivo data.
- •
Results suggest that application in closed-loop control is feasible.
