Audible noise levels of oxygen masks operating on venturi principle.
نویسنده
چکیده
Certain oxygen therapy masks operating with a venturi were found to possess audible noise levels sufficient to cause annoyance to the user. This was not true of all masks. However, it is recommended that this is a source of noise pollution that should be eliminated by the manufacturers of such devices.

Compliance at night with low flow oxygen therapy: a comparison of nasal cannulae and Venturi face masks.
BACKGROUND The factors that influence nocturnal compliance among patients prescribed low flow oxygen therapy were determined and tolerance of nasal cannulae and Venturi face masks compared. METHODS Two studies were performed: (1) a prospective study of 99 hospitalised patients prescribed low flow oxygen therapy, 49 on nasal cannulae and 50 on Venturi face mask; and (2) a prospective study of ...
متن کاملShould we judge a mask by its cover?
BACKGROUND A table of the approximate ranges of inspired oxygen delivered at given oxygen flow rates is often given on the packaging of oxygen masks. A study was carried out to check the inspired oxygen concentration given by one of the new masks, which has been designed to be used with or without the Venturi attachment as a result of the proposal to use it without the Venturi attachment as a g...

BACKGROUND The likely values of inspired oxygen concentration (FIO2) of patients with chronic obstructive pulmonary disease breathing via nasal cannulas have not been assessed previously. METHODS Seven patients with chronic obstructive lung disease and seven healthy subjects were studied while breathing oxygen via nasal cannulas or fixed performance (Venturi) or uncontrolled (MC) oxygen masks...
متن کاملOxygen therapy during exacerbations of chronic obstructive pulmonary disease.
Venturi masks (VMs) and nasal prongs (NPs) are widely used to treat acute respiratory failure (ARF) in chronic obstructive pulmonary disease (COPD). In this study, these devices were compared in terms of their potentiality to worsen respiratory acidosis and their capacity to maintain adequate (> 90%) arterial oxygenation (Sa,O2) through time (approximately 24 h). In a randomized cross-over stud...
متن کاملHealth-Based Audible Noise Guidelines Account for Infrasound and Low-Frequency Noise Produced by Wind Turbines
Setbacks for wind turbines have been established in many jurisdictions to address potential health concerns associated with audible noise. However, in recent years, it has been suggested that infrasound (IS) and low-frequency noise (LFN) could be responsible for the onset of adverse health effects self-reported by some individuals living in proximity to wind turbines, even when audible noise li...
