It is now more than 60 years since the polio epidemic in Denmark in 1952 that led, at least partly, to the development of artificial ventilation.1 In the report of that epidemic, Lassen stated that “A good humidifier is essential: otherwise incrustation of secretions may occur.” Subsequent to the polio epidemic, a heated humidifier was described by Marshall and Spalding in 1953,2 and Drägerwerk...
The pressures and resistances of a bubble humidifier (Bennett Cascade) and a blow-by humidifier (Fisher and Paykel) were measured and computed at gas flow rates from 4.5 to 100 litre min-1. Pressures increased with flows, with the Bennett pressures being greater at all flows. The resistance of the Fisher-Paykel increased with flows, but remained less than that of the Bennett. An inverse resista...
Three workers developed classical extrinsic allergic alveolitis while working in a printing works that had a contaminated cold water humidifier. All had nodular shadows on their chest radiographs, reduced gas transfer measurements, and lung biopsy specimens that showed an alveolitis with giant cells and cholesterol clefts. In two subjects bronchoalveolar lavage was performed and the lavage flui...
BACKGROUND In April 2011 a tertiary hospital in Seoul, Korea reported several cases of severe respiratory distress of unknown origin in young adults. METHODS To find the route of transmission, causative agent and patient risk factors of the outbreak, an investigation of the epidemic was initiated. Clinicopathological conferences led to the suspicion that the cases related to an inhalation inj...
A descriptive approach for automatic generation of visual blends is presented. The implemented system, the Blender, is composed of two components: the Mapper and the Visual Blender. The approach uses structured visual representations along with sets of visual relations which describe how the elements – in which the visual representation can be decomposed – relate among each other. Our system is...
Sixty staff working in a hospital operating theatre, where a case of humidifier fever had been identified, were studied together with 49 subjects working in other parts of the hospital. They each had a blood test for serology, a skin test, and a chest radiograph and completed a questionnaire. The theatre staff also had pulmonary function tests. The theatre humidifier was found to contain severa...
South Korea had a rapid industrialization after 1960s. 81.5 % of the country’s population lives in urban areas (1). A study shows 37.2 % of citizen use a humidifier and half of them employ humidifier disinfectants (2). It is very popular among urban citizen because of closed dry atmosphere in winter season. In 2011, unconfirmed viral lung disease was reported as a cause of pregnant death by Kor...
Once released into the air, humidifier disinfectants became tiny nano-size particles, and resulted in chemical bronchoalveolitis. Families had lost their most beloved members, and even some of them became broken. Based on an estimate of two million potential victims who had experienced adverse effects from the use of humidifier disinfectants, we can say that what we have observed was only the t...
Air was "breathed" in the laboratory through a heated-water humidifier and a breathing tube. Several different humidifiers and tubes were used. The temperature rise of the air on passing through the humidifier and the temperature drop on passing through the tube were measured. Both were dependent on ventilation. Insulating the tube and humidifier together with the insertion of baffles in the la...
