Abstract:
Lower extremity ischemic complications are frequently encountered after femoral cannulation for venoarterial extracorporeal membrane oxygenation (VA-ECMO). Many are attributed to mechanical obstruction of distal arterial blood flow related to intraluminal positioning of the arterial cannula. Routine use of distal perfusion catheters is ineffective at eliminating the development of these serious complications. Side- arm grafting instead of direct arterial cannulation is suggested as an alternative. Here, the authors present a case wherein a patient developed suspected lower extremity ischemia from hyperperfusion after femoral VA-ECMO cannulation during use of an arterial side- arm graft, calling into question the benefits of this cannulation strategy.

Jugular Venous Pressure (JVP) Measurement
Position the patient at a thirty- to forty-five-degree angle or in a semi-fowler's position. Look for the highest point of pulsation in the internal jugular vein and measure the vertical distance to the angle of Loius or sternal angle. A normal JVP is 3-4 cm above...
