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.
An inexpensive yet portable device for calibrating four different flow meters in the undergraduate fluid mechanics laboratory was designed and constructed. The apparatus contains a rotameter, a turbine-type meter, a venturi meter, and an orifice meter. All four meters are calibrated simultaneously using a volumetric measuring tank. Results obtained by undergraduate students are presented, and a...

The development of hydrodynamics metamaterials and transformation has enriched the methods fluid flow control. In proposed study, coupling rotation amplification functions, hydrodynamic rotating concentrators with tensorized viscosity are designed based on hydrodynamics. Through numerical simulations, we have demonstrated that can simultaneously magnify rotate velocity in creeping flows. centra...
BACKGROUND Postoperative continuous positive airway pressure (CPAP) can improve lung function. The aim of our study was to assess the efficacy of prophylactic CPAP on the Pa(O2)/FI(O2) ratio measured the day after surgery in patients undergoing lung resection surgery (LRS). METHODS The study population comprised 110 patients undergoing LRS. On arrival in the postanaesthesia care unit (PACU), ...
