Abstract Background N95 respiratory protection masks are used by healthcare professionals to prevent contamination from infectious microorganisms transmitted droplets or aerosols. Methods We conducted a rapid review of the literature analyzing effectiveness decontamination methods for mask reuse. The database searches were carried out up September 2020. systematic was in way which simplified st...

BACKGROUND High-flow nasal cannula (HFNC) creates positive oropharyngeal airway pressure and improves oxygenation. It remains unclear, however, whether HFNC improves thoraco-abdominal synchrony in patients with mild to moderate respiratory failure. Using respiratory inductive plethysmography, we investigated the effects of HFNC on thoraco-abdominal synchrony. METHODS We studied 40 adult subje...

Objectives: This study aims to examine changes due masks healthcare workers who respiratory for long hours emergency room during pandemic process. Methods: Cross-sectional and prospective was carried out with professionals an FFP2 type valve mask. The participants’ transcutaneous...

Twenty-nine patients with a neuronopathic or neuropathic disorder were referred for assessment of respiratory insufficiency between 1978 and 1994. Diagnoses included spinal muscular atrophy (6), chronic idiopathic demyelinating neuropathy (4), Vialetto-van Laere syndrome (3), hereditary motor and sensory neuropathy (3) and a miscellaneous group (5). We also describe seven patients with Guillain...

BACKGROUND Plating and pickling processes are the most effective ways for increasing the strength of metal structures, and workers in these units are exposed to various contaminants, including acid mists. The aim of this study was to investigate the effect of protective masks in decreasing the respiratory symptoms and the aerobic capacity of workers that are exposed sulfuric acid mist. METHOD...

We investigated a nosocomial infection of severe acute respiratory syndrome (SARS) in Vietnam in 2003 and attempted to identify risk factors for SARS infection. Of the 146 subjects who came into contact with SARS patients at Hospital A, 43 (29.5%) developed SARS, and an additional 16 (11%) were asymptomatic but SARS-coronavirus (CoV) seropositive. The asymptomatic infection rate accounted for 1...
