Work-related asthma and other respiratory health effects that occur after acute, occupational inhalation exposures to chlorine, isocyanates, formaldehyde, glutaraldehyde, and other sensitizing and/or irritant agents arewell documented [Ross and McDonald, 1996; Sallie and McDonald, 1996; Olin et al., 1999; Henneberger et al., 2003; Henneberger et al., 2005; McDonald et al., 2005; Andersson et al., 2006].

An outbreak of acute respiratory syndrome following exposure to waterproofing sprays occurred during the winter 2002-2003 in Switzerland. About 180 cases were reported by the Swiss Toxicological Information Centre between October 2002 and March 2003, whereas fewer than 10 cases per year had been recorded previously.

Signs of potential inhalation injury include facial burns, singed nasal vibrissae, carbonaceous sputum, abnormal mental status (agitation or stupor), respiratory distress (dyspnea, stridor, hoarseness, wheezing), or an elevated carboxyhemoglobin level of greater than 10%, especially in a closed-space fire. 33,34 The initial carboxyhemoglobin level should be calculated from the time the admission level is

Signal processing circuit 34 receives signals S and Sd and compares these signals to determine the occurrence of the inhalation and exhalation phases of the respiratory cycle. Specifically, signal S is received at the negative input terminal of comparator A3 (type 358A) and signal Sd is received at the positive input terminal thereof by way of ...

Inhalation injury represents one of the most serious associated injuries complicating the care of thermally-injured patient. It can result in severe respiratory failure and acute respiratory distress syndrome (ARDS) by three mechanisms—thermal or chemical injury, and impairment of systemic oxygen supply. Thermal injury can cause erythema, ulceration, and progressive, life-threatening oedema ...

Acute V2O5 dust inhalation produced significant air-flow limitation in both central and peripheral airways without producing any detectable changes in parenchymal function. These functional changes were accompanied by a significant increase in the total cell counts recovered from the lungs by BAL.

2014-1-1 Potential exposure from inhalation of atmospheric CUPs was calculated using the following equation: (3) PE = C × RR × D BW where PE is the potential exposure from inhalation (mg kg −1 d −1), C is the total air concentration (pg m −3), RR is the respiratory rate (m 3 h −1), D is the duration of exposure, or the cumulative time spent ...

2015-10-1 BACKGROUND: Foreign body aspiration is an uncommon entity in adults. Herein, we describe our experience with flexible bronchoscopy in the removal of tracheobronchial foreign bodies in adults. We also conducted a systematic review of the literature on the topic of foreign body inhalation in adults managed with flexible bronchoscopy. METHODS: The bronchoscopy database (from 1979 to

R.K. Wolff, in Comprehensive Toxicology (Third Edition), 2018 9.20.9 Conclusions. Inhalation toxicology studies provide an important basis for evaluating the toxic potential of a material. The material provided in this article gives an overview of the conduct of inhalation toxicology studies. The review in this article is intended to provide a framework around which to build a toxicology ...

The toxicology of fragrance materials is largely well understood. Although most are benign, a minority have the potential to cause adverse health effects, notably allergic contact dermatitis resulting from skin sensitization. As a consequence, industry guidelines have banned certain materials and st

2020-8-1 It is evident that inhalation of aggressive and corrosive chemicals can aggravate airway tissue injuries, and that daily repeated exposures will further exacerbate injury of the respiratory mucosa causing inflammatory reactions, and ultimately “irritant-induced” asthma (Siracusa et

2011-7-29 The key difference between breathing and respiration is that the breathing is a physiological process that takes air in and out from the respiratory system while the respiration is a biochemical process that utilizes oxygen and produces energy through the breakdown of glucose..
