A negative pressure ventilator, often referred to colloquially as an iron lung, is a nearly-obsolete mechanical respirator which enables a person to breathe on their own in a normal manner, when muscle control is lost, or the work of breathing exceeds the person’s ability, as may result from certain diseases (e.g. poliomyelitis, botulism) and.

On average, people in the United States spend about 90 percent of their time indoors. Since the majority of people’s daily activities take place inside, the atmosphere inside of homes has a major impact on the health and safety of the majority of the population.

Social Learning. Last week, at the Underwriters Laboratories (UL) Firefighter Safety Research Institute (FSRI) Advisory Board Meeting, we discussed changes in the fire environment over the last 40 years and also explored how to effectively roll out the new UL Vertical Ventilation on-line course.

Ventilatory failure is a rise in Paco 2 (hypercapnia) that occurs when the respiratory load can no longer be supported by the strength or activity of the system. The most common causes are severe acute exacerbations of asthma and COPD, overdoses of drugs that suppress ventilatory drive, and.
