Removal of Mycobacterium species by breathing circuit filters.

چکیده
Breathing circuit filters (BCFs) are used in respiratory and critical-care settings for humidification of air and to limit transmission of respiratory pathogens. Three types of BCFs (Pall BB 25A, BB 100, and HME 15-22) were evaluated (in triplicate) for removal of Mycobacterium species. Filters were challenged with aerosolized Mycobacterium bovis (a surrogate for Mycobacterium tuberculosis), at minimum total concentrations of 10(4) colony-forming units. No M bovis was recovered in the effluent, providing removal efficiencies of > 99.99% to > 99.999% for the filters tested.

An in vivo evaluation of the mycobacterial filtration efficacy of three breathing filters used in anesthesia.
BACKGROUND The use of breathing filters (BFs) has been recommended to protect the anesthesia apparatus in proven or suspected cases of tuberculosis. Some investigators have also suggested the use of BF to alleviate the need to change anesthesia breathing circuits after each case. This study evaluated the filtration efficacy of three different BFs to prevent mycobacterial contamination of breath...
متن کاملCan breathing circuit filters help prevent the spread of influenza A (H1N1) virus from intubated patients?
INTRODUCTION In March 2010, more than 213 countries worldwide reported laboratory confirmed cases of influenza H1N1 infections with at least 16,813 deaths. In some countries, roughly 10 to 30% of the hospitalized patients were admitted to the ICU and up to 70% of those required mechanical ventilation. The question now arises whether breathing system filters can prevent virus particles from an i...
متن کاملBacterial contamination of anesthesia machines’ internal breathing-circuit-systems
BACKGROUND Bacterial contamination of anesthesia breathing machines and their potential hazard for pulmonary infection and cross-infection among anesthetized patients has been an infection control issue since the 1950s. Disposable equipment and bacterial filters have been introduced to minimize this risk. However, the machines' internal breathing-circuit-system has been considered to be free of...
متن کاملAdsorption of desflurane by the silica gel filters in breathing circuits: an in vitro study
BACKGROUND During general anesthesia, a heated breathing circuit (HBC) is used to replace the heat and moisture exchange function of the upper airway. One HBC uses an air dryer filter that employs silica gel (SG) as a desiccant. SG is capable of adsorbing many organic compounds. Therefore, we undertook an in vitro study of the adsorption of desflurane by SG filters. METHODS An HBC was connect...
متن کاملClass-AB Square-Root Domain Filters Based on the Floating
In this paper a new approach for design of class-AB current-mode square-root domain filters based on the electronically simulated translinear loop principle is presented. FG-MOS transistors that operate in strong inverted saturation region are employed for implementation of translinear loop circuit. The filter achieves immunity to body effect, low circuit complexity, large input dynamic ran...
