Abstract:

Background: Management of critically ill patients in austere environments is a logistic challenge. Availability of oxygen cylinders for the mechanically ventilated patient may be difficult in such a context. One solution is to use a ventilator able to function with an oxygen concentrator (OC).

Methods: We tested two Elisée™ 350 ventilators paired with SeQual Integra 10-OM oxygen concentrators (OC) (Chart Industries, http://www .chartindustries.com) and evaluated the delivered fraction of inspired oxygen (Fio2). Ventilators were connected to a test lung and Fio2 was measured and indicated by the ventilator. Continuous oxygen was generated by the OC from 0.5L/min to 10L/min, and administered by the specific inlet port of the ventilator. Several combinations of ventilator settings were evaluated to determine the factors affecting the delivered Fio2.

Results: The Elisée 350 turbine ventilator is able to deliver a high Fio2 when functioning with an OC. However, modifications of the ventilator settings such as an increase in minute ventilation, inspiratory-to-expiratory ratio, and positive end-expiratory pressure affect delivered Fio2 despite steady-state oxygen flow from the concentrator.

Conclusion: OCs provide an alternative to oxygen cylinders for delivering high Fio2 with a turbine ventilator. Nevertheless, Fio2 must be monitored continuously, since it decreases when minute ventilation is increased.
