Capillary refill time and tissue oxygen saturation as factors influencing lower limb ischemia in VA-ECMO: a case-control study
StO<sub>2</sub> reflects real-time tissue perfusion adequacy, whereas CRT serves as a marker of microvascular dysfunction. Lower StO<sub>2</sub> levels (indicating impaired oxygenation) and higher CRT levels (suggesting delayed capillary refilling) were independently associated with an increased risk of lower limb ischemia, suggesting that monitoring these parameters may be useful in identifying patients at higher risk for this complication. These findings provide valuable insights for risk stratification and potential intervention strategies in the management of VA-ECMO patients.
