[Assessment of an oxygen dilution device with a ventilatory mask (author's transl)].
Oxygen dilution devices (Venturi 3 and 4) with Multi-VentTM mask, using an oxygen flow rate of 6 1/min, are insufficient when subjects' ventilation is increased : inspired oxygen concentration is lower than predicted. This can be detrimental to patients who could benefit by oxygenotherapy during exercise.
