[Oxygen enrichers and different ways of using them].
Different ways of using oxygen enrichers have been studied. First, the performances of two different devices were tested: the results were very similar to the constructors' previsions. Second, oxygen concentrations in venturi masks connected to enrichers were measured with a mass spectrometer. The authors suggest to adjust the flow delivered by enrichers at 3 liters/min for any type of venturi mask. Pharyngeal oxygen concentration curves show the reliability of masks connected to enrichers compared to other modes of administration (nasal cannulae, nasal catheter).
