A simple method of carbon dioxide estimation in expired air.
A SIMPLE method for the estimation of carbon dioxide in air or gas mixtures containing anaesthetic gases finds many applications in the investigation of anaesthetic problems and in the control of artificial respiration by mechanical respirators. This adaptation of already established techniques utilizes apparatus which may be found in most hospitals. It is rapid, and can be performed at the bed...
متن کاملAir Toxic Concentrations: Response
more detailed explanation of the basis for MCIA's position. Woodruff et al. (1) incorrectly suggest that industrial air emissions of methyl chloride present a significant health risk. On the basis of 1990 data for the Toxics Release Inventory (TRI) and the Cumulative Exposure Project (CEP), Woofruff et al. purport to identify listed hazardous air pollutants (HAPs) that are present in the enviro...
متن کاملCriteria air pollutants and toxic air pollutants.
This review presents a brief overview of the health effects and exposures of two criteria pollutants--ozone and particulate matter--and two toxic air pollutants--benzene and formaldehyde. These pollutants were selected from the six criteria pollutants and from the 189 toxic air pollutants on the basis of their prevalence in the United States, their physicochemical behavior, and the magnitude of...
متن کاملIsoprene from expired air inside a private car.
The concentration of isoprene inside a small-sized parked private car with one person was found to be of the order of 20 micrograms/m3. Isoprene was then the major non-methane volatile hydrocarbon except in strongly traffic-polluted parking places. On driving, with intermediate fan ventilation, the isoprene levels were one order of magnitude lower. In the empty car, the concentrations were stil...
متن کاملA technique for evaluating expired air mixing devices.
A simple method for measuring the efficiency of expired air mixing devices is described. Preliminary studies comparing a number of mixing chambers indicate that the bag-inbottle system is the most efficient. The dependence of mixing efficiency on VT, f and expired flow rate is demonstrated. Two types of mixing failure are distinguished. The clinical implications are discussed, including those r...
