Noninvasive face mask ventilation has been used successfully in patients with paralytic respiratory failure. This study evaluated whether noninvasive face mask ventilation can be used for patients with acute respiratory failure due to intrinsic lung disease. Six patients with hypercapnia and four with hypoxemic acute respiratory failure met clinical and objective criteria for mechanical ventila...

The reproducibility and acceptability of airways resistance measurements using the interrupter technique (MicroRint) obtained using a mouthpiece were compared with those using a face mask. Fifty children aged 4-7 yrs performed four sets of six Rint measurements; two using a mouthpiece and two using a face mask with integral mouthpiece. Complete data were obtained from 45 (90%) children using th...

The development of the positive airway pressure custom mask (TAP-PAP CM) has changed the treatment of obstructive sleep apnea. The TAP-PAP CM is used in continuous positive airway pressure therapy (CPAP) and is fabricated from the impression of the face. This mask is then connected to a post screwed into the mechanism of the TAP3 (Thornton Anterior Positioner) oral appliance. This strapless CPA...

In this paper we present a system for preserving the privacy of individuals in video sequences by obfuscation of facial appearance, so as to render recorded people unrecognizable. Therefore we address the following two problems: automatic face detection and scrambling of face region. A multi-resolution access control scheme is used in order to decrease the visual quality of regions containing f...

Growing concern over the availability of Respiratory protective devices (eg, filtering facepiece Respirators), in the face of the probable extreme demand brought on by a pandemic influenza, has prompted the suggestion that useful life of N95 filtering facepiece Respirator can be extended by the concurrent use of a surgical mask as an outer protective barrier over the Respirator. Personal protec...

BACKGROUND Governments are preparing for a potential influenza pandemic. Therefore they need data to assess the possible impact of interventions. Face-masks worn by the general population could be an accessible and affordable intervention, if effective when worn under routine circumstances. METHODOLOGY We assessed transmission reduction potential provided by personal respirators, surgical mas...

We present an application of Viola-Jones face detection and exemplar-based inpainting to automatically select and remove unwanted background person(s) in photographs. We experiment with using various source and target region masks as well as patch and neighbourhood selections to produce realistic inpaintings. The final pipeline is able to generate results comparable to those achieved with manua...
