BACKGROUND We compared the efficacy of medical masks, N95 respirators (fit tested and non fit tested), in health care workers (HCWs). METHODS A cluster randomized clinical trial (RCT) of 1441 HCWs in 15 Beijing hospitals was performed during the 2008/2009 winter. Participants wore masks or respirators during the entire work shift for 4 weeks. Outcomes included clinical respiratory illness (CR...

The success of transpyloric feeding in a group of babies weighing 1500 g or less was evaluated. This method was successful for most well babies but for many of those who required respiratory assistance (usually by face mask) it was not.

UNLABELLED Study objective-To investigate the correlation between the Respi-check sensor and simultaneous chest auscultation in determining the respiratory rates in adults. METHODS Random visits to a local accident and emergency (A&E) department were made and all patients wearing oxygen masks were recruited into the study. The new sensor was attached to the outside of the mask. One researcher...

BACKGROUND Pneumonia viruses such as influenza may potentially spread by airborne transmission. We studied the dispersion of exhaled air through a simple oxygen mask applied to a human patient simulator (HPS) during the delivery of different oxygen flow in a room free of air currents. METHODS The HPS represented a 70-kg adult male individual in a semi-sitting position on a hospital bed inclin...

BACKGROUND Oxygen supplementation through Hudson type face mask is frequently used in perioperative settings. Hudson mask is a variable rate performance device with the risk of rebreathing. Studies using capnography to find out an actual fraction of rebreathing in spontaneously breathing patients are not available. AIMS In this study, we analyzed the effects of different flow rates through Hu...

OBJECTIVE Compare the short-term benefit of high-flow nasal cannula (HFNC) with non-rebreathing mask in terms of change in dyspnea, physiologic variables, and patient comfort in subjects after endotracheal extubation. METHODS A randomized crossover study was conducted in a 10-bed respiratory care unit in a university hospital. Seventeen mechanically ventilated subjects were randomized after e...

examination was normal. An arterial blood gas showed respiratory alkalosis with pH 7.51, PCO2 3.2 kPa, PO2 20 kPa, and HCO3 20.4. A repeat brain CT with bone window showed right frontal pneumocephalus and a large defect near the cribriform plate on the right side (Fig. 1C).The pneumocephalus was managed with supportive care and the patient was discharged on posttrauma day 27. Recurrent pneumoce...

BACKGROUND Although the estimated risk of life-threatening adverse respiratory events during supraglottic airway device use is rare, the reported rate of events leading to failure of the airway device is 0.2-8%. Little is known about the risk-adjusted prediction of Laryngeal Mask Airway failure requiring rescue tracheal intubation and its impact on patient outcomes. METHODS All adult patients...
