Legendair ventilatorLegendair ventilator manufactured by Covidien.

Product codes of affected devices in the UK: 4095701 and 4095901.

This is a portable ventilator, which can be used in a homecare environment. The
Field Safety NoticePDF file (opens in new window) (1074Kb) refers to a number of product codes but only devices with codes 4095701 and 4095901 are affected in the UK.

The manufacturer has found that, in the event of a total mains power failure, the battery backup alarm may fail due to degradation of components necessary to power this alarm.

This could result in either a total loss of the final battery alarm or a decrease in the volume or duration of the alarm.

The manufacturer has not had sufficient confirmation from users that they have received the Field Safety NoticePDF file (opens in new window) (1074Kb) (dated 20 May 2011) and acted on this information.

The final battery alarm, indicating that the ventilator is no longer functioning follows three low battery warning alarms:

  • Alarm 1 – when 5% of internal battery is remaining, a continuous alarm will sound until reconnected to the mains.
  • Alarm 2 – when five minutes is remaining.
  • Alarm 3 – when battery is almost depleted.
  • Alarm 4 (final) – when battery is depleted.

However, a component failure could lead to a decrease in volume or duration of the final alarm, or no audible alarm at all.

  • To confirm that the performance of the audio alarm is within specification, carry out the additional test as detailed in the manufacturer’s Field Safety NoticePDF file (opens in new window) (1074Kb).
  • This additional test should be completed as soon as possible, rather than waiting for the annual service.
  • If the alarm fails, please follow the manufacturer’s instructions in the Field Safety NoticePDF file (opens in new window) (1074Kb).
  • Until the test has been completed, the ventilator must be operated under mains power and with a fully-charged internal battery.
  • Return the verification form to the manufacturer.
