What is the size of gas filters used in perfusion, measured in microns?

Gas filters used in perfusion are typically designed to have a size of 0.2 microns. This size is critical for effectively filtering out bacteria and particulates from the gas that is delivered during the procedure, such as oxygen. The 0.2-micron filter is small enough to capture the majority of harmful pathogens while allowing for the passage of gases. Ensuring that these filters are utilized helps maintain the safety and efficacy of the perfusion process by preventing contamination of the patient’s circulatory system. Therefore, the choice of 0.2 microns reflects the standard practice in the field for ensuring optimal filter performance in cardiopulmonary bypass and other perfusion-related activities.
