Blood Recirculation and vvECMO

Measurment of Blood Recirculation and Adjustment of vvECMO Blood Flow During Veno-venous Extracoporeal Membrane Oxygenation

A prospective, observational study will be performed measuring recirculation of blood through a veno-venous Extracoporeal Membrane Oxygenation (vvECMO) in patients with acute respiratory distress syndrome (ARDS) on vvECMO. ECMO blood flow will be adjusted with respect to recirculation.

Inclusion Criteria:

• patients aged 18 years or older
• ARDS
• veno-venous ECMO

Exclusion Criteria:

• age < 18 years
• hemodynamic instability during measurement of recirculation
• pregnancy
• inability to obtain patient's consent or consent of legal guardian
