Cleaning and Maintenance

Introduction
To ensure proper ventilator operation and minimize risk of cross
contamination, perform the following cleaning and maintenance
procedures at the recommended intervals. All procedures should be
adapted to your institution’s policies and procedures. All personnel
should use precautions to minimize the risk of spreading infection
when disassembling, cleaning and performing maintenance
procedures on the ventilator system.
Use of Filters
Inspiratory (To Patient) Port
The gas that enters the breathing circuit through the Inspiratory
(To Patient) Port of the ventilator is usually clean and dry; however,
Newport Medical strongly recommends using a filter at this port for
two reasons:
1. To protect the inspiratory manifold from potential contaminants in
patient gases, and
2. To protect the patient from potential contaminant in the delivered
gas.
By using the filter, the need for regular cleaning and sterilization of
the inspiratory manifold is reduced. By replacing the filter between
each patient use, the risk of infection being spread between patients
is reduced.
Expiratory (From Patient) Port
Gas that enters the Expiratory (From Patient) Port on the ventilator
from the breathing circuit may be moist and contain pathogens.
Newport Medical strongly recommends the use of a dry, clean filter in
this location for three reasons:
1. To protect the expiratory manifold from potential contaminants in
exhaled gases;
2. To protect the patient from potential contaminants in the
exhalation system should the patient pull gas in through the
expiratory limb of the circuit;
3. To protect the staff from potential contaminants in the patient
gases.
When a filter placed on the From Patient port gets wet, filtration
capabilities are diminished and resistance to patient exhalation
increases. By keeping a clean, dry filter in this location, the need for
regular cleaning of the exhalation valve and flow sensor is reduced,
