Objective:

To compare EVLWI values obtained from AI-based automated CT segmentation with those derived from transpulmonary thermodilution and to derive a correction factor for TPTD in VV ECMO patients, enhancing clinical accuracy.

Key Findings:
  • AI-based CT segmentation provides a reliable assessment of EVLWI independent of ECMO-related hemodynamic interference, potentially transforming clinical assessment.
  • TPTD-derived EVLWI may be overestimated due to the confounding effect of extracorporeal blood flow, necessitating careful interpretation in clinical settings.
  • A correction factor for TPTD-derived EVLWI was developed to enhance its accuracy in VV ECMO patients, improving fluid management strategies.
Interpretation:

AI-based CT analysis may offer a more accurate and practical method for assessing pulmonary edema in ARDS patients on VV ECMO compared to TPTD.

Limitations:
  • Single-center study may limit generalizability of findings; further multicenter studies are needed.
  • Retrospective design may introduce selection bias, affecting the reliability of the results.
  • Potential inaccuracies in manual segmentation used for comparison could impact the validity of the findings.
Conclusion:

AI-based automated CT segmentation is a promising tool for assessing EVLWI in ARDS patients on VV ECMO, potentially improving fluid management strategies and patient outcomes.
