Maintenance Precautions
WARNING
•
Never use a ventilator or any components or accessories that appear to be damaged. If any signs of
damage are evident, contact your equipment supplier or Puritan Bennett.
•
If you cannot determine the cause of a problem with your ventilator, contact your equipment supplier.
Do not use the ventilator until the problem has been corrected.
•
Except for replacing the internal battery and cleaning the device, do not try to repair or otherwise
service the ventilator yourself, or modify the ventilator, its components, or accessories. Doing so might
endanger the patient, cause damage to the ventilator, and/or void your warranty. Only qualified
service personnel should attempt repair of the ventilator.
•
On a daily basis, ensure the proper connection and operation of the patient circuit.
•
If a problem with the ventilator is suspected, FIRST CHECK THAT THE PATIENT IS NOT IN DANGER. If
necessary, remove the patient from the ventilator and provide an alternative means of ventilation.
•
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.
•
Use all cleaning solutions and products with caution. Read and follow the instructions associated with
the cleaning solutions you use to clean your ventilator. Use only those solutions listed in
Table 7-1 .
•
Do not attempt to repair or otherwise service the ventilator yourself. Doing so might endanger the
patient, damage the ventilator, and/or void your warranty. Only qualified service personnel should
repair or service the ventilator.
•
If the ventilator is damaged or its external housing is not correctly closed or it behaves in a way that is
not described in this manual (excessive noise, heat emission, unusual odor, alarms not triggered during
the start-up procedure), the oxygen and power supplies should be disconnected and use of the device
stopped immediately.
•
The exhalation block is intended for single use by a single patient. It may periodically be cleaned, but it
cannot be disinfected or sterilized. To maintain good measurement quality when used continuously,
trained personnel should clean the exhalation block periodically. The exhalation block should be
changed every 3 months and cannot be reused with any other patient.
•
Ensure that the exhalation block is completely dried after cleaning and prior to use.
•
When an exhalation block is set up, each time it is removed, or after installing a new exhalation block
on the machine, it is essential that the expiratory flow sensor be recalibrated before the exhalation
block is used; refer to section 10.1, “Calibrating the Expiratory Flow Sensor” in the Clinician’s Manual.
•
The patient circuit is intended for single use by a single patient and should be changed according to the
manufacturer’s recommendations. Refer to the instructions for use supplied by the manufacturer of the
patient circuit (included with the ventilator) and chapter
4, “Installation and Assembly” .
•
A patient treated by mechanical ventilation is highly vulnerable to the risks of infection. Dirty or
contaminated equipment is a potential source of infection. Clean the ventilator and its accessories
regularly and systematically before and after each use and following any maintenance procedure to
reduce the risks of infection. The use of a bacterial filter at the ventilator’s outlet—or both ports if a
double-limb circuit is used—is recommended. Refer to chapter
7, “Cleaning” .
•
When replacing the ventilator’s internal battery, the ventilator must be disconnected from all external
power supplies and turned off.
•
Never touch the ventilator’s internal components, including the battery, and the patient
simultaneously.
•
Regularly check the cleanliness of the air inlet filter located on the rear of the ventilator. If necessary,
replace the filter before the recommended replacement period is over (see section 10, “Routine
Maintenance in the Clinician’s Manual). This is particularly important when the ventilator is installed on
a wheelchair, because environmental conditions may cause the filter to become dirty more rapidly.
