Abstract
Abstract Objective: To compare the work of breathing imposed and patient tolerance to the delivery of face mask continuous positive pressure ventilation by three different ventilators. Methods: Eleven healthy volunteers were subject to continuous positive pressure ventilation at levels of 0, 5, 10 and 15 cmH2O on each of the three machines tested (Oxylog 2000, Drägerwerk AG, Lubeck, Germany; Puritan-Bennett 7200, Puritan Bennett Corp., Carlsbad, CA, USA; Auspap, Ulco Engineering Pty Ltd, Marrickville, NSW, Australia). The work of breathing imposed by the machines was measured using the Bicore-CP100 pulmonary function monitor (Allied Healthcare Products, CA, USA). After breathing on the three machines, volunteers rated the comfort of breathing on a visual analogue scale. Results: The work of breathing imposed by the Oxylog 2000 was higher in all volunteers receiving face mask continuous positive pressure ventilation when compared with both the Puritan-Bennett 7200 and the Auspap. The Oxylog 2000 was considered to be the least comfortable. Conclusions: The provision of continuous positive pressure ventilation in the emergency department is becoming increasingly common, but the use of a transport ventilator, such as the Oxylog 2000, to provide this ventilatory support cannot currently be recommended.
