The double limb circuit adaptor is single
use and disposable. Only using
an expiratory filter and observing its manufacturer recommendations can
prevent from cross-contamination and allow its reuse.
Single limb with intentional leak:
1. Attach any required accessories e.g. humidifier or filter
2. Connect the inspiratory tubing to the inspiratory port on the front of the device
3. According to the desired configuration, connect the proximal pressure line to the proximal
pressure port or connect the proximal free plug as shown below.
4. Ensure the appropriate calibrated leak is integrated in the mask or added to the circuit.
5. Select the Leak circuit type and patient type (adult/pediatric) in the menu and perform a
calibration (without the leak).
