(J. Extra-Corpor. Technol. 20(2):63–66) The following is a design for a simple, inexpensive negative pressure alarm, with specific applications in neonatal Extracorporeal Membrane Oxygenation (ECMO).
In a typical roller pump driven ECMO system, if the pump flow rate exceeds the heart’s venous return, or if for any reason there is insufficient blood flow into the tubing system, the negative pressure alarm disables the pump and activates alarms.
The unavailability of such a modular device, through commercial manufacturers, has facilitated the need for ECMO centers to fabricate their own alarm systems.
