Filtration of Breathing Gases- Filtration of contaminated breathing gases is a necessary measure in mechanical ventilation.There are two types of filters available for filtration of breathing gases: mechanical filters and electrostatic filters. Use of these filters can potentially minimize the risk of infection and cross-contamination to patients, caregivers and visitors in the critical care setting. For optimal filter function, attention must be paid to factors such as humidity, airflow rate, filter drying or obstruction, decreased performance with anesthetic gases, and the possible buildup of toxic gases in closed anesthesia circuits.
