Introduction |
| This guide describes how to replace the Puritan Bennett 840 Re/X800 Expiratory Bacterial Filter. | | The expiratory filter is responsible for filtering out impurities and particulates from the gas or air flowairflow within the ventilator, and redirects said impurities into the collector vial. | | | Before completing the replacement, it is important that you are familiarized with the expiratory filter and collector vial system. Please ensure that all safety measures are followed to replace the filter successfully. | | There are two types of expiratory filters–reusable filters and single-use filters. Single -use filters must be discarded each time the collector vial must be emptied. Reusable filters must be sterilized using a steam autoclave. These instructions are applicable to both types of filters, providing that the user understands how to use autoclaves. |
