Dr. Pramod Chembrammel, together with Pavithra Rajeswaran, HCESC Simulation Engineer, and Dr. Matt Bramlet of OSF Health Care System, are developing a simulator that will train the surgeons to quickly deploy extra corporeal membrane oxygenation (ECMO) for failing heart/lungs. Safety is a corner stone of medicine, but is more robust in engineering, specifically in the aviation, computer, and communications industries. Similar to aviation, they use simulation protocols that replicate basic steps of ECMO from vascular access to cannulation and connection to ECMO. The simulator includes peripheral arterial and venous
access in a simulated critically ill or unstable patient followed by percutaneous deployment and open cannulation of the femoral artery and vein in preparation for ECMO set up. The system simulates common clinical conditions such as difficult access, extreme hemodynamic instability, hypoxemia, etc., while providing realistic immersive experiences such as pulsations and blood flow in the underlying vessels. The operation of the simulator is based on a mathematical physiology model that controls a system of programmable pump and valves to simulate various hemodynamic flow patterns while responding to the cannulation and oxygenation.
