ELSA Monitor

“Transonic's ELSA monitor quantitatively measures oxygenator clotting which we implemented with our COVID-19 ECMO patients to improve our bedside decision making in circuit component change-outs." Patrick Weerwind, perfusionist at Maastricht University Hospital

Extracorporeal Life Support Assurance

The ELSA® Monitor is the latest development in extracorporeal life support monitoring. Identify presence and amount of oxygenator clotting by measuring the oxygenator blood volume using a bolus of saline. Trending graphs for oxygenator blood volume are available directly on the ELSA® for easy tracking of volume changes indicative of clot formation. Additionally, recirculation measurements during VV ECMO ensures optimal placement of dual lumen catheters and relative heart response to ECMO therapy.

The ELSA® is a stand-alone ECMO Monitor with a rechargeable battery for portability. The intuitive touchscreen clearly presents all pertinent patient data, and is easy to clean, thereby preventing cross-contamination.
