    Abstract

    The effect on flammability of endotracheal tubes exposed to helium diluted oxygen was measured by the Oxidant O2 (He) index of flammability and compared to the corresponding oxidant O2 (N2) indices of flammability. The oxidant O2 (He) index of flammability for PVC (Portex) ETT is 0.274, for RR ETT 0.194, and for Si ETT 0.194. The differences between helium dilution values and the corresponding nitrogen dilution values are statistically significant, the greatest difference being a factor of 1.2. However the common clinical practice of adding helium as a diluent for oxygen in situations with a potential for flammability may not increase patient safety.
