Cleaning and Maintenance
8-4 Operator's Manual
Reusable circuits should be cleaned and disinfected between patients and as needed while in
use. Always use a clean, disinfected exhalation valve (and humidifier/probe assembly if appropri-
ate) when a breathing circuit is reassembled for patient use. Clean and disinfect in accordance
with the instructions provided by the manufacturer.

Caution:
To avoid damage to a reusable circuit, attach and detach the circuit by grasping the cuffs at the
end of the circuit tubing. Do not pull or twist the circuit tubing.
To clean the reusable breathing circuit and exhalation valve:
1.
Use a low flow of running water or low flow of air to clear tubings and passages of organic
matter.
2.
Wash all components of the breathing circuit and exhalation valve with a soft brush in a mild
medical detergent and rinse thoroughly with sterile, distilled water.
3.
Shake off excess water and place all parts on a clean towel to air dry. (Do not heat or blow dry.)
Always follow the cleaning instructions provided by the manufacturer.
To disinfect and sterilize the circuit and exhalation valve, refer to the instructions provided by the
breathing circuit and exhalation valve manufacturer.
8.5
Air Intake Filter
The air intake filter, located on the right side of the ventilator behind the filter cover, keeps dirt and
particles out of the ventilator’s piston system and patient gas pathway. As the filter becomes dirty,
it can reduce the volume of air drawn into the ventilator and add stress to the pump. Check the
intake filter weekly and replace it with a new filter when the majority of the filter surface area is no
longer white. Intake filters are not reusable.

WARNING:
NEVER operate the Newport HT70 Ventilator without a clean air intake filter in place. NEVER
reverse the air intake filter when dirty.
8.6
Proximal Inline Filter
Check the proximal (prox) inline filter weekly and replace it at least every 3 months. Discard the
filter and replace with a new one if it appears to have gotten wet or come in contact with a con-
taminant. Proximal inline filters are not reusable. If the filter becomes occluded, replace the filter.
The primary indication for this would be a Check Circuit or Prox Line alarm.
Covidien strongly recommends that extra prox inline filters be available at all times when using
the Newport HT70 Ventilator.
