Replacing Ventec One-Circuit Components
Follow your healthcare institution’s protocol for cleaning and replacement of Ventec One-Circuit components, as well as
any instructions and recommendations for replacement provided by Ventec One-Circuit accessory manufacturers. Inspect
all accessories including your humidier or HME, nebulizer, external bacterial lter, and any other accessories for signs of
damage. Discontinue use and replace any damaged Ventec One-Circuit accessories immediately.
NOTE: Ventec Life Systems recommends running a Pre‑Use Test each time the Ventec One‑Circuit conguration is
modied. See “Running the Pre-Use Test” on page 34 for instructions.
Replacing the External Bacterial Filter
The external bacterial lter is intended for single-patient use. Replace the external bacterial lter between patient uses,
whenever it becomes soiled or damaged, or every 30 days (at a minimum). Follow your healthcare institution’s protocol
for replacement criteria.
