We report a fatal case of community-acquired Legionnaires' disease in an infant aged under six months. Epidemiological and microbiological investigations suggested that a free-standing cold water humidifier using domestic tap water contaminated with Legionella pneumophila serogroup 1 served as a vehicle for infection. These findings were corroborated by sequence-based typing (SBT). Humidifier-a...

The objective of this study was to modify an existing liquid desiccant and indirect/direct evaporative cooling-assisted 100% outdoor air system (LD-IDECOAS) for humidification operation in winter. energy benefit the desiccant-assisted approach during LD-IDECOAS over conventional method with a steam humidifier evaluated through detailed simulation. enthalpy effectiveness values measured from lab...

The aim of this work was to improve the understanding dry matter losses (DML) that occur in wood chips during initial phase storage outdoor piles. For purpose, a laboratory scale chamber developed and investigated regarding its ability recreate conditions undergo storage. Three trials with poplar Max-4 (Populus maximowiczii Henry × Populus nigra L.) were performed for 6–10 weeks under controlle...

Recently, a novel humidifier that sprays water fine droplets equipped with copolymer, poly(3,4-ethylene dioxythiophene)–poly(styrene sulfonate) (PEDOT/PSS) was developed. PEDOT/PSS in the absorbs from environment and releases by heating. In present study, effect of hydration on skin barrier, stratum corneum, first determined application using humidifier. The skin-penetration enhancement model h...

BACKGROUND The effectiveness of aerosol drug delivery during mechanical ventilation is influenced by the patient, ventilator, and nebulizer variables. The impact of nebulizer type, position on the ventilator circuit, and bias flow on aerosol drug delivery has not been established for different age populations. OBJECTIVE To determine the influence of nebulizer position and bias flow with a jet...

Following the recent press release regarding the toxicity of the biocides mixed in the water of humidifiers as a cause of fatal pulmonary syndrome among pregnant women and young children in Korea [1], the use of humidifiers has became a public concern. There are few reports, however, on the use of humidifiers with children suffering from atopic dermatitis. Those children use humidifiers more fr...

BACKGROUND Noninvasive positive-pressure ventilation (NPPV) delivers air at a high flow, which is associated with airway mucosal drying and impaired airway functioning. OBJECTIVES To examine the effects of mechanical ventilation parameters on relative humidity and absolute humidity during NPPV, and to evaluate the effect of a heated passover humidifier on relative humidity, absolute humidity,...
