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.
