Over the past 10 years, the number of percutaneous coronary intervention procedures performed in the United States increased by 33%; however, restenosis, which inhibits complete functional recovery of the vessel wall, complicates this procedure. A wide range of anti-restenotic therapeutics have been developed, although many elicit non-specific effects that compromise vessel healing. Drawing ins...

BACKGROUND AND PURPOSE Our aim was to determine the diagnostic accuracy of multisection CT angiography combined with matched mask bone elimination (CTA-MMBE) for detection of intracranial aneurysms compared with digital subtraction angiography (DSA) and 3D rotational angiography (3DRA). MATERIALS AND METHODS Between January 2004 and February 2006, 108 patients who presented with clinically su...

PURPOSE We sought to compare the ability of novice operators to provide artificial ventilation using a standard facemask and a new ergonomically designed facemask. Whether or not proper technique was used was also assessed. METHODS Thirty-two allied-health students used both masks in random crossover fashion to ventilate an airway trainer. Breaths were delivered by a mechanical ventilator and...

This paper describes the automated creation of a textured face mask of a natural person suitable for realtime animation. A 3D surface polygon face mask is used. A set of muscles is defined to animate the mask. The mask is adapted to a real person using 3D surface data from a calibrated stereo sensor. Firstly, the facial features of the mask are aligned to the 3D data by scaling the mask. Second...

background: cuffed pharyngeal tube is a device designed for ventilation of anesthetized patients. cpt has advantages over face mask including: maintaining of face mask can be difficult and boring after several minutes and mobility of the practitioner is reduced due to involvement of hands. mask pressure can cause soft tissue and nerve damage around the nose. anesthetic gas leakage from the mask...

The purpose of this study was to compare the effects of wearing different kinds of masks on the ear canal temperature, heart rate, clothing microclimate, and subjective perception of discomfort. Ten subjects performed intermittent exercise on a treadmill while wearing the protective masks in a climatic chamber controlled at an air temperature of 25 degrees C and a relative humidity of 70%. Two ...

To determine factors that predispose or protect healthcare workers from severe acute respiratory syndrome (SARS), we conducted a retrospective cohort study among 43 nurses who worked in two Toronto critical care units with SARS patients. Eight of 32 nurses who entered a SARS patient's room were infected. The probability of SARS infection was 6% per shift worked. Assisting during intubation, suc...

Mask ventilation is lifesaving, especially in cases of difficult intubation. Many publications have offered distinct techniques for optimizing mask ventilation. This article reviews currently available difficult mask ventilation literature and theory. We divide difficult mask ventilation into 3 broad categories based on etiology: inadequate mask seal, increased airway resistance, and decreased ...
