Recirculation in VV #ECMO: ⚗️🐖 study investigating factors influencing the phenomenon using a controlled bench model comprising a VV #ECLS circuit + mock circulatory loop with animal model simulating human right heart anatomy Several single (SLC) + dual lumen cannula (DLC) configurations, different cannula positions, blood flow, cardiac output, CVP assessed for impact 📏 with SLC, cannula size or retraction beyond threshold distance had minimal effect on recirculation 📏 with DLC exact positioning crucial, as suboptimal placement or rotation markedly increased recirculation 🫀CO & CO/EBF ratio key determinants in all cannulation scenarios 🖥️ accurate monitoring of recirculation & CO may optimize extracorporeal oxygen transfer efficiency, and to support troubleshooting ASAIO Journal 🖇️ https://bit.ly/4mpXQbh (fb)

Optimal #PEEP & recruitment-to-in patients with severe #ARDS undergoing ultra‑protective lung ventilation during VV #ECMO 🔍 bicentric cohort study including 54 patients 🫁 R/I ratio feasible, providing valuable indications for guiding PEEP titration 🫁 R/I ratio > 0.34 may help identify patients likely to benefit from further individualized PEEP optimization using EIT 🫁 R/I ratio ≤ 0.34? moderate PEEP (8-10 cmH₂O) may suffice, making additional EIT-based assessment less critical Open access #FOAMcc #FOAMecmo 🔓 https://rdcu.be/emH1e (fb)
