Clinical Study of VA-ECMO Remote Limb Re-perfusion Monitoring Technology

Clinical Study of VA-ECMO Remote Limb Re-perfusion Monitoring Technology

Establish and verify the feasibility and effectiveness of VA-ECMO remote limb re-perfusion monitoring technology.

It is proposed to monitor VA-ECMO arterial end side branch circulation in real time through a set of monitoring equipment, guide clinical adjustment, improve lower limb re-perfusion, reduce the occurrence of lower limb ischemia, in order to achieve the goal of early detection, early prevention and early treatment, and provide reference and theoretical basis for clinical practice.

Monitoring techniques are divided into two parts: A. monitoring equipment (connecting transdiotic monitoring pressure on va-ECMO side branches cycle); B.to guide clinical adjustment by monitoring pressure (average arterial pressure).

Inclusion Criteria:

• Age: adult patients ≥ 18 years of age;
• signed ECMO informed consent;
• femur vein VA-ECMO treatment;
• agreed to establish VA-ECMO side branch cycle;
• informed consent to this study.

Exclusion Criteria:

• a completely closed double lower limb venously before surgery;
• amputee
