This study evaluated workplace performance of a full facepiece, negative pressure, air-purifying respirator with P100 filters in a lead refining plant. Air samples for lead were collected inside and outside the respirators worn by workers who were properly trained and quantitatively fit tested. Trained observers assisted in the study to ensure sample validity. Three to four pairs of air samples...

Purpose. Emergency physicians are at risk for infection during invasive procedures, and the respirators can reduce this risk. This study aimed to determine whether endotracheal intubation using direct laryngoscopes affected protection performances of respirators. Methods. A randomized crossover study of 24 emergency physicians was performed. We performed quantitative fit tests using respirators...

Diseases can be transmitted via many routes, including inhalation of aerosols. When properly fitted and maintained, particulate-removing respirators have been demonstrated to reduce the amount of aerosols – both bioaerosols and nonbiological aerosols – that are inhaled by the wearer. In contrast, most surgical masks are not designed to seal tightly to the face, and research has shown that they ...

the routine intake of surfactant as a part of hmd (hyaline membrane disease) treatment had significant effect on the prognosis of premature neonates. but since in our country this drug is not widely and routinely used, and there are not records about its use, we decided to make good on this shortcoming through a retrospective study. during 1 year, 54 neonates with hmd were admitted in ali-asgha...

The feasibility of electrocardiography (ECG)-synchronized respiration with an external cuirass-type respirator in cardiac magnetic resonance (MR) imaging was evaluated. Cardiac MR imaging was performed in 10 nonsedated healthy volunteers with an ECG-triggered external respirator that was modified for use in the MR environment. Coronary MR angiograms and multiphase gradient-echo cine images were...
