Open Access Abstract Introduction We observed an oscillatory flow while ventilating critically ill patients with the Drager Oxylog 3000 transport ventilator during interhospital transfer. The phenomenon occurred in paediatric patients or in adult patients with severe airway obstruction ventilated in the pressure-regulated or pressure-controlled mode. As this had not been described previously we conducted a bench study to investigate the phenomenon. Methods An Oxylog 3000 intensive care unit ventilator and a Drager Medical Evita-4 NeoFlow intensive care unit ventilator were connected to a Drager Medical LS800 lung simulator. Data were registered by a Datex-S5 Monitor with a D-fend flow and pressure sensor and were analysed with a laptop using S5-Collect software. Clinical conditions were simulated using various ventilatory modes using various ventilator settings using .
