Puritan Bennett 560 Ventilator User's Manual - Covidien

Installation and Assembly
After assembling, cleaning, or reassembling the patient circuit, and on a daily basis, inspect the
hoses and other components to ensure that there are no cracks or leaks and that all connections
are secure.
To ensure proper performance of the ventilator, use a patient circuit recommended by Covidien
in this manual; refer to chapter 4, “Installation and Assembly” and Appendix F, “Parts and
Accessories”. The total specified length of the patient circuit tubing as measured from the
ventilator outlet to the ventilator inlet is 1.1 metres (3.6 feet) to 2.0 metres (6.6 feet). The tubing
must conform to all applicable standards and must be fitted with Ø 22 mm terminals that also
conform to all applicable standards. Ensure that both the length and the internal volume of the
patient circuit are appropriate for the tidal volume: a corrugated tube of Ø 22 mm for adult
patients, and a corrugated tube of Ø 15 mm for pediatric patients with a tidal volume lower
than 200 ml.
Adding accessories to the ventilator breathing circuit, such as a humidifier and water trap(s),
may result in a decrease in tidal volume delivered to the patient due to the added compressible
volume of the accessory. Always assure that the patient is receiving the appropriate inspired
volume when altering the breathing circuit configuration.
Users must always possess an additional breathing circuit and exhalation valve while using the
Puritan Bennett 560 Ventilator.
4.4.1 Choosing the Patient Circuit Type
Single limb circuits are used with breathing modes where spirometry measurements are not required, and double
limb circuits are used with breathing modes where spirometry is required. Be sure to choose the appropriate
circuit in the menu preferences; in particular, ensure that Pediatric Circuit Yes/No is set to YES when using
a pediatric circuit (refer to chapter F, “Parts and Accessories”).

4.4.2 Installing the Patient Circuit
The patient circuit is mounted depending on the setup of the circuit used and the accessories used.
The following procedures describe the installation of the patient circuit with a humidifier. To add other accessories,
refer to the installation instructions for the specific accessories used.
To connect a single limb circuit with an exhalation valve: (refer to Figure 4-7)
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, as shown.
3. Attach one end of the short circuit tubing (item 2) to the bacteria filter (item 1).
4. Attach the other end of the circuit tubing (item 2) to the inlet port of the humidifier (item 3).
5. Place a water trap (item 4) between the outlet port of the humidifier and the inlet of the
exhalation valve (item 5).
6. Ensure the exhalation valve (item 5) is placed as close as possible to the patient.
7. Connect one end of the proximal pressure tubing (item 7) to the proximal pressure port on the
exhalation valve (item 5) and the other end onto the ventilator patient pressure port (item 8).
8. Connect one end of the exhalation valve tubing (item 6) to the exhalation valve port on the
exhalation valve (item 5) and the other end onto the ventilator exhalation valve port (item 9).
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).
