Fully charge built-in accumulator before every using of ventilator with the
connection to the patient.
Presence of the accumulator in the device demands considering features of
its operation (see below).
•
Device operating time in the independent mode depends on the accumulator capacity, its
previous charge level and time passed after that, quality of the accumulator, terms of its
operation, and also from the operating mode of the device.
•
During long-term operation or storage there can be reduction of accumulator capacity,
therefore time of independent operation of the device can be reduced. That can not be a
reason for claims to the manufacturer.
•
For the maintenance of capacity and increasing of the service life of the accumulator it is
necessary to conduct periodically its training (at least once a half a year) (see Section 6).
If the device is connected to the mains power, but the indicator “accumulator” is red, it means
that charging device and/or the accumulator are faulty and need repair. Operation of such
device is forbidden, because it does not provide possibility of operation at interruptions of power
supply.
In some cases, at malfunction of the accumulator, the device can continue ventilation in the
presence of mains supply. Also at the detection of the accumulator failure during the device
operation, ventilation does not stop, but the accumulator indicator on the screen blink with red
color.
In this situation it is necessary to prepare immediately other means for the
patient ventilation and be ready to use them. When operating with the faulty
accumulator, power supply interruptions can cause switching off the device
and the ventilation termination without any warnings.
Responsibility for negative consequences of operation of the device with
the faulty accumulator lies on medical staff of the medical facility.
