•
Do not conduct the ventilator alarm test while the patient is connected to the ventilator. Switch
the patient to an alternate means of ventilation before testing.
•
The setting of the Min PIP alarm must be adjusted for the patient, but must also be set high
enough to allow the PATIENT DISCONNECTION alarm to trigger properly. Perform the Low
Pressure Test to ensure the Min PIP alarm is properly set.
•
If APNEA TIME is set to a value higher than 60/Control R then the APNEA alarm will not activate.
•
If an APNEA alarm is required, set the APNEA setting to YES in the Preferences Menu.
•
The Apnea Alarm should be set to YES for ventilator dependant patients.
•
Setting Alarm limits to extreme values can cause the ventilator alarms to malfunction.
•
Ensure the Insp Time setting is compatible with the physiological requirements of the patient.
•
Adjustable alarms should not be systematically cancelled; instead, they should be adjusted
according to the needs and condition of the patient.
•
A continuous alarm condition will be activated if the ventilator power switch is turned off while
ventilation is in progress. When the power switch is turned back on again, the ventilation will
resume without having to press the VENTILATION ON/OFF button.
•
In the SIMV mode the use of a double limb circuit is recommended. The Min VTE setting should
remain active in the event that pressure losses are present on the patient circuit downstream
from the proximal pressure link. In such cases the "PATIENT DISCONNECTION" alarm would not
be systematically activated in case of a disconnection of the circuit.
•
The inspiration trigger threshold should be carefully modified in order to avoid the risk of false
triggering or "autotriggering" of the ventilator. For example, Level 1P, the most sensitive mode,
is recommended for pediatric use. However, for an adult, this setting may result in
autotriggering.
•
The sound level of the alarms should be adjusted according to the installation environment and
the size of the area monitored by the patient's caregiver. Ensure that the alarm sound apertures
at the front of the device are never obstructed.
Warnings Regarding USB Memory Device
•
Always verify the file ID before using a USB memory device to transfer data between the
ventilator and a PC.
Warnings Regarding Maintenance
•
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 Covidien.
•
To ensure proper servicing and avoid the possibility of physical injury to personnel or damage to
the ventilator, only personnel authorised and qualified by Covidien should attempt to service or
make authorised modifications to the Puritan Bennett™ 560 Ventilator.
•
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.
•
To ensure proper performance of the ventilator, the preventative maintenance schedule should
be followed. For further information contact Covidien.
•
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.
