Activity Summary

Required reading for all learners: Implicit Bias impacts patient outcomes

Weaning from veno-arterial extracorporeal membrane oxygenation (VA-ECMO) support is a real challenge and the echocardiogram is fundamental. We found as echocardiographic parameters related to weaning success a higher left ventricular outflow tract time–velocity integral, 1:1 aortic valve opening, and qualitative normal right ventricular function, highlighting the left ventricular ejection fraction (LVEF) as independent predictor with a cut-off value >33.4%.

Objectives

  • Describe the challenge of weaning patients with hemodynamic instability off of venoarterial extracorporeal membrane oxygenation (VA-ECMO).
  • Identify echocardiographic parameters during the weaning test related to final successful disconnection from VA-ECMO.
  • Find an optimal cutoff point of left ventricular ejection fraction to discriminate patients with successful VA-ECMO weaning.

Continuing Education Disclosure Statement

Successful Completion

Learners must attend/view/read the entire activity, read Implicit Bias impacts patient outcomes, and complete the associated evaluation to be awarded the contact hours or CERP. No partial credit will be awarded.

Accreditation

The American Association of Critical-Care Nurses is accredited as a provider of nursing continuing professional development by the American Nurses Credentialing Center's Commission on Accreditation.

Provider approved by the California Board of Registered Nursing, Provider number CEP 1036, for 1.00 contact hours.

Accreditation refers to recognition of continuing education only and does not imply AACN, ANCC, or CBRN approval or endorsement of any commercial products discussed or displayed in conjunction with this educational activity.

Disclosure

Any relevant relationship between an ineligible company and an individual with the ability to influence clinical content will be identified by the Nurse Planner within the activity. Any relevant relationship between an ineligible company and an individual with the ability to influence clinical content has been mitigated.

AACN programming meets the standards for most states that require mandatory continuing education contact hours for license and/or certification renewal. AACN recommends consulting with your state board of nursing or credentialing organization before submitting CE to fulfill continuing education requirements.
