The pressure and control lines are attached correctly, with the
pressure line (green) connecting the bottom of the valve to the blue
port on the CCV marked PATIENT AIRWAY and the control line
(clear) connecting the top of the valve to the silver port on the CCV
marked EXHALATION VALVE. Connecting these tubes improperly
will prevent the ventilator from functioning and will cause errors.
HME Filter
When receiving mechanical ventilation, a patient is at risk for ventilator-
associated pneumonia (VAP). Keeping the gas delivered to the patient
warm and humid can help reduce this risk.
Some ventilators use active humidifiers, but these often fail due to lack
of diligent maintenance or the availability of distilled water. The CCV is
designed to work with disposable Heat/Moisture Exchanger (HME)
filters, which trap the heat and moisture in a patient’s exhaled breath
and use it to warm and humidify the gas inhaled in the next breath.
They also serve as bacterial filters to prevent bacteria from the patient
from entering the breathing circuit. The HME should be placed between
the control valve and the patient as shown below.
