Filter Maintenance; Filter Replacement - Covidien Puritan Bennett Instrucciones De Uso

Note: Covidien recognizes that cleaning, sterilization, sanitation, and disinfection
practices vary widely among health care institutions. It is not possible for Covidien
to specify or require specific practices that will meet all needs, or to be responsible
for the effectiveness of cleaning, sterilization, and other practices carried out in the
patient care setting. We do recommend that users of this product that require cleaning
and sterilization/disinfection consider the Standards and Recommended Practices for
sterilization published by Association for the Advancement of Medical Instruments
(AMI) as well as the Center for Disease Control (CDC) publication: A guideline for
Prevention of Nosocomial Pneumonia.

Filter Maintenance

Remove and steam sterilize the Re/X700 filter after each patient use. Look for any
visible damage to the filter housing or media. Replace the filter if the filter body or
the end caps are cracked, or if the filter media is visibly damaged. Check the filter flow
resistance before each reuse. See Figure 1.

Filter Replacement

The Re/X700 filter is designed to withstand up to 100 repeated autoclave sterilization
cycles at temperatures not exceeding 135ºC (275ºF). Covidien recommends inspecting
the filter before each reuse and discarding it if the filter housing or media is visibly
damaged or if the filter flow resistance is too high for your application. Covidien
recommends that use of the filter be discontinued if flow resistance is greater than
4 cmH O at 100 L/min flow.

Covidien recommends replacing the filter after a maximum of one year of service or
after 100 steam autoclave cycles, whichever occurs first. For your convenience, a space
is provided on the side of the filter to note anticipated retirement date. Calculate an
expected filter retirement date based on your typical use rates.
