Abstract
Aim. The main purpose of this work is to evaluate the Hemolung pumping ability and gas exchange effectiveness while using the catheters of smaller diameter and blood fl ow rates, applied in pediatrics.
Material and methods. The bench testing of the device with pediatric catheters has been performed. The bovine blood and carboxymethylcellulose water solution were used as a model. The device operation data, blood gas analysis and hydrodynamic pressure data were collected.
Results. The pump curve results show that at the maximum rotation rate the Hemolung device was able to achieve blood fl ow rates substantially greater than targeted 280 ml/min that is used in pediatrics. The calculated operating curve plotted against the observed pressure-fl ow relationships
