Guidelines for ECMO in COVID-19 patients

ELSO has prepared an in-depth set of guidelines for ECMO in COVID-19 patients. These have been collaboratively developed by a global team of ECMO experts. The guidelines include: patient selection criteria, cannulation and decannulation strategies, transport on ECMO, PPE and staff protection strategies with ECMO, to ethical dilemmas and quality. ELSO wants to recognize the leadership of Kiran Shekar in chairing the development of these guidelines during a critical time.
