Figure 14: Exhalation Valve Positions
The Exhalation valve is now connected and ready to use. The next step involves
installing the tubing to the ventilator.
To install the patient circuit:
1. Assemble the PEEP control tube by connecting one end to the barb fitting of
the exhalation valve and the other end to the barb fitting of the reusable Luer
fitting.
2. Connect the assembled PEEP control tube by securing the luer lock fitting to
the Exhalation valve luer inlet, which is marked with a blue dot on the front
panel of the ventilator (see figure 1, item number 4).
3. Secure the multi-use one way valve to the ventilator patient outlet (see figure
1, item number 5)
4. Connect the patient circuit inspiratory limb to the one way valve sitting on
the ventilator patient outlet and the expiratory limb to the exhalation valve.
5. If appropriate, fit the patient wye to the inspiratory and expiratory patient
circuit tubes.
6. Secure the flow sensor to the patient wye and connect the 2 sensor lines to
the ventilator sensor line luer inlets (see figure 1, item number 6).
Note: even though the luer lock fittings at the end of the flow sensor
sampling lines are non-interchangeable, it is good practice to verify that the
left (while facing the ventilator) male luer connector connects to the fitting on
the flow sensor which is closest to the patient
WARNING Before connecting a patient to the ventilator with a new circuit, you
must perform a complete Operational Verification Test (O.V.T.) as
described on page 60
