ELSA Monitor Survey Results

The Extracorporeal Life Support Assurance (ELSA) monitor improves patient care and optimizes ECMO therapy by measuring delivered blood flow, oxygenator blood volume and recirculation.

We recently surveyed 40 healthcare providers (including perfusionists and intensivists) from seven countries. Our goal was to better understand how they use the ELSA monitor to support patient care.

Recommend frequent use of the ELSA system for recirculation, oxygenator blood volume and delivered flow measurements.

*Survey conducted in December 2021.

How ELSA is used

Nearly all the clinicians surveyed use the ELSA monitor to support patients on extracorporeal membrane oxygenation. Out of the 40 clinicians who responded, 11 also reported using the ELSA monitor to support cardiopulmonary bypass patients.

The ELSA system is most frequently used for adult patients, but just over half of respondents used it for neonatal and pediatric patients as well.

Impact on care

Measurements provided by the ELSA device give critical insights that help improve patient care.

Impact of recirculation measurements

Three-quarters of healthcare providers reported the recirculation measurements helped inform better clinical decisions for the patient, including managing pump flow, indicating hypovolemia and identifying low cardiac output.

If these measurements had not been available, it may have resulted in a consequential delay or other negative impacts for more than a third of patients.

Report that the ELSA recirculation measurements improve the position of the cannula.

Impact of delivered blood flow measurements

Eight of ten clinicians who were surveyed use ELSA for delivered blood flow measurements and 97% of them reported that the information assisted in patient management. If the blood flow measurements had not been available or consistently reproducible, it would have negatively impacted treatment for more than half of patients.

Ease of use

The clinicians who were surveyed reported high levels of satisfaction using the ELSA system.

Report the flow sensors were easy to clip onto the arterial and venous lines of the circuit.

Find the measurement instructions easy to read and follow on the display monitor.

Describe the ELSA device as easy to transport within the ICU.

Impact of oxygenator blood volume measurements

Just under half of surveyed clinicians reported using ELSA for oxygenator blood volume (OXBV) measurements. Thanks to this data, 80% were able to make better clinical decisions, such as properly timing oxygenator changes. These accurate and timely measurements prevented delays that could have negatively impacted treatment for 43% of patients.
