Puritan Bennett 560 Exhalation Block Replacement

Introduction

This guide will explain how to remove and replace the exhalation block in the Puritan Bennett 560 Ventilator. If you decide to clean the exhalation block for use on the same patient follow the proper use procedures below.

Proper Use:

The exhalation block is for a single patient only and must be replaced for each new patient.
It can be removed from the ventilator and cleaned for use on the same patient by washing with soap and water.
If cleaning the exhalation block, ensure that it is completely dry before reinserting it back into the ventilator. This ensures that no damage is done to the ventilator electronics.
- The exhalation block can either be left to air-dry, or blown dry with compressed air.

The repair information is also available on pages 144-145 (Section 5, Pages 14-15) of the Service Manual that is linked in the documents section.
