ECMO Flow Calculator

ECMO Cannula Flow Calculator

VV-ECMO Recirculation Calculator

This calculator determines the percentage of recirculation during VV-ECMO using oxygen saturation values.

Saturation of blood entering the oxygenator (SpreO2) (%): Saturation of blood leaving the oxygenator (SpostO2) (%): Saturation of blood in the pulmonary artery (SvO2) (%):

RESP Score Calculator

The RESP score is used to calculate expected in-hospital mortality in patients undergoing ECMO for respiratory failure (e.g. VV-ECMO). Patients with non-respiratory indications (e.g. cardiogenic shock) were excluded from the cohort used to develop this score.
