What is it indicated for?

The CAPIOX Hemoconcentrator is designed to remove excess fluid from the blood in order to maintain proper hematocrit and protein concentration during cardiopulmonary bypass and to enable reinfusion of blood remaining in the circuit after bypass.

It is intended to be used during and after surgical procedures requiring cardiopulmonary bypass (up to 6 hours) when the removal of excess fluid from blood is required. It should not be used as a dialyzer, hemofilter or other device.

Indications for use read by OCR from a scanned FDA summary, so letters may be misread. Check the PDF before quoting it.
