ABSTRACT
The CO2 plastic bag system is a spinoff of principles learned during 26 years in
developing a computerized CO2 delivery system. We have used the plastic bag for
over 13 years, using the present iteration of the plastic bag system in over 1000
patients during the last nine years, without complications secondary to CO2 delivery.
With the present system, there is no possibility of injecting excessive volumes, and it
markedly reduces the possibility of injecting air. The multiple check valves enable
very simple, expedient CO2 deliveries without stopcock manipulation. It is also ideal
for interventional procedures when injections between the catheter and guidewire are
beneficial.
