Troubleshooting
In this topic, the main occurrences and the possible solutions are presented.
Occurrence
Probable causes
Proposed solution
Low battery alarm
Depletion of internal battery charge.
Connect the equipment to the electrical
outlet or provide other means of
ventilatory support.
Internal battery charging system
failure, even with power.
Contact technical assistance for service.
Disconnect alarm
Disconnection in the respiratory
circuit.
Locate the disconnect point and firmly
connect all parts of the breathing circuit.
Lack of inspiratory flow.
Check for inspiratory flow and increase if
necessary.
Alteration of the patient's respiratory
mechanics.
Establish adequate parameters for
ventilatory support.
Integrated valve diaphragm placed
incorrectly or damaged.
Replace or return the diaphragm to the
correct position.
Failure of the electronic control
system.
Contact technical assistance for service.
Communication failure alarm
Electronic fault.
Contact technical assistance for service.
High pressure alarm
Alteration of the patient's respiratory
mechanics.
Establish adequate parameters for
ventilatory support.
Obstruction in the expiratory branch
of the respiratory circuit or in the
integrated valve.
Clear the circuit of any obstruction or
reposition the integrated valve
diaphragm.
Obstruction of the patient's airway.
Unclog or aspirate the patient's airway.
Monitored inspiratory pressure is
higher than expected.
Check the inspiratory pressure (absolute)
setting, which is the sum of the controlled
(relative) pressure and PEEP.
Tube Compensation is on.
Turn off or reconfigure tube
compensation.
Low pressure alarm
Alteration of the patient's respiratory
mechanics.
Establish adequate parameters for
ventilatory support.
Excessive leakage in the respiratory
circuit.
Locate the leak and correct.
Electrical network alarm
Disconnected power cord.
Properly connect the power cord to the
equipment or in case of in-hospital
transport, check that there is enough
battery power.
Power failure.
Try to reestablish a power source.
Inoperable Alarms
Electronic failure.
Contact technical assistance for service.
Incorrect control of PEEP
Calibration of the integrated valve.
Restart the equipment and calibrate the
integrated valve.
