AVEA ventilator systems Appendix A: Contact and Ordering Information 191
L2786 Rev. M
AVEA Maintenance should only be performed by a trained and authorized service technician. CareFusion will make
available to qualified technicians, service manuals, which include such items as circuit diagrams, component parts lists,
calibration instructions and other information to assist in repair of those parts of the ventilator designated by the
manufacturer as repairable items.
WARNING
If a mechanical or electrical problem is recognized while operating the ventilator, the ventilator must be
removed from use and referred to qualified personnel for servicing.
Using an inoperative ventilator may result in patient injury.
Battery Care
The AVEA has an internal, Nickel Metal Hydride battery pack that will provide power
backup for short periods in the event that the mains power supply is lost (Figure 8–1).
Under normal operating conditions and when fully charged, the internal battery is capable
of powering the ventilator alone for 1 hour or the ventilator and compressor for 30
minutes.
Figure 8–1: Internal Battery Pack
Note:
The internal battery is intended only for short duration backup in the event of disruptions in line power. The internal
battery provides 30 minutes of battery power for the ventilator and compressor nominally. The recharging cycle for this
battery can be 4 hours or more depending on the state of discharge. Should you wish to perform intra-facility transport
of patients you should equip your instruments with the optional external battery. The addition of the external battery will
extend the time period to 2 hours for ventilator and compressor.
CareFusion recommends that when used in transport situations the expected transport time should not be greater than
50% of the usable battery life. This provides a safety margin in the event of schedule delays or premature consumption
of the battery power. Should the expected transport time be delayed beyond this, a dedicated transport system should
be considered. As with any patient transport, suitable manual ventilation backup should be available.
CAUTION
Prior to operating on battery power, the internal (and external if connected) battery indicator(s) should be green. The
ventilator should be connected to a mains AC power supply until the battery indicator(s) show green prior to operating
on battery power.
An optional sealed lead-acid (SLA) external battery pack is also available. This can significantly extend the operating
period of the ventilator when it is not connected to an AC source. Under normal operating conditions, fully charged
