چکیده
Motion by releasing the oxygen from the cylinder. There was also a bag (as in Haldane's oxygen apparatus) Which served to keep the oxygen pressure from rising too high in the delivery tube. Thus the oxygen on its Way to the face kept the pump working, and this produced alternately a negative and positive pressure in the delivery tube provided the face-piece was closely applied to the face. This apparatus has been successfully used in mine-rescue work. When Hawlinson's army made its famous advance in front of Amiens on 8th August, 1918, a surprisingly large

Performance of mechanical filters and respirators for capturing nanoparticles--limitations and future direction.
There is an increasing concern about the health hazard posed to workers exposed to inhalation of nanoparticles. Inhaling nanoparticles possess an occupational hazard due to elevated amount emitted to the atmosphere and working environment. Nanoparticles have potential toxic properties: the high particle surface area, number concentration, and surface reactivity. Inhalation, the most common rout...
متن کاملProtective value of dust respirators in extrinsic allergic alveolitis: clinical assessment using inhalation provocation tests.
Six subjects with budgerigar fancier's lung, pigeon breeder's lung, or mushroom worker's lung underwent identical paired inhalation provocation tests of 20 minutes to five hours duration (mean 2.3 hours) using a natural method of antigen exposure. For one test of each pair, the subjects were protected by the use of industrial dust respirators that incorporate electrostatically charged, resin-im...
متن کاملHistological Evaluation of the Fetus Lung in NMRI Mice after Exposure to Iron Oxide Nanoparticles: an in vitro Study
Background and Aim: Iron oxide nanoparticles are used in fields related to nanotechnology including ecology, magnetic storage, imaging and medicinal purposes. Iron nanoparticles produce reactive oxygen species (Ros). These materials are able to cross the placenta. The aim of this study was to investigate toxic effect of iron oxide nanoparticles on fetal lung in mice. <br ...
متن کاملPhysiological studies of the effects of intermittent positive pressure breathing on cardiac output in man.
Three types of positive pressure breathing have been differentiated : a) continuous positive pressure breathing where a pressure above atmospheric is maintained in the lungs throughout the respiratory cycle, b) expiratory positive pressure breathing in which a pressure above atmospheric is present during the expiratory phase of breathing, and c) intermittent positive pressure breathing (IPPB), ...
متن کاملMEDICAL SECTION OF THE AMERICAN LUNG ASSOCIATION Respiratory Protection Guidelines
Respirators (respiratory personal protective devices) are an essential component of programs for protecting workers against inhaled toxins. They are occasionally used in other settings such as protecting patients against inhaled irritants and for protecting military personnel civilian populations against chemical, biologic, or nuclear warfare. In most instances, those using respirators will be ...
