Association Between Pulmonary Artery Pulsatility Index and Radial Artery Pulse Pressure and Successful Separation from Peripheral Veno-Arterial Extracorporeal Membrane Oxygenation: A French Single-Center Retrospective Study From 2017 to 2021
Authors' conclusion
Higher PAPi and rPP were predictors of successful weaning from VA-ECMO in this retrospective study.
Study context

- 124 patients
- Exposure
- Successful vs unsuccessful weaning from VA-ECMO, by PAPi and rPP
- rPPn = 124
- PAPin = 82
- Outcome
- rPP and PAPi
