9. To protect the exhalation port (as it will not be used in this configuration), place the cap (if
provided with the breathing circuit) over the exhalation port opening (item 10).
To connect a double limb circuit, do the following and refer to Figure 4-8 :
1. Inspect the components of the patient circuit for any signs of damage, such as cracks (which might
cause leakage). Do not use damaged components to assemble the patient circuit.
2. Install the bacteria filter (item 1) on the TO PATIENT outlet port.
3. Attach one end of the short circuit tubing (item 4) to the filter (item 1).
4. Attach the other end of the circuit tubing to the humidifier’s inlet port (item 2).
5. Place a water trap (item 3) between the outlet port of the humidifier and the patient wye (item 5)
on the double limb circuit.
6. Place a water trap (item 3) between the patient wye and the inlet port of exhalation filter (item 5).
7. Connect one end of the small proximal pressure tubing (item 6) as close as possible to the patient
at the level of the double limb patient wye circuit connection (item 5) and the other end on the
ventilator patient pressure port.
8. Ensure that the water trap (item 3) on the expiratory limb of the patient circuit (item 7) is securely
installed between the patient wye (item 5) and the exhalation valve (item 9).
Note:
When shipped, the proximal pressure tube may already be connected to the patient wye. If so, simply verify that
the connection is secure and the tube shows no signs of damage, kinks, or obstructions.
