  • Notas adicionales en la data
    The occurrence of the problem is extremely rare, due to the 50-millisecond time window in which both actions must occur: the detection by the instrument of a disconnection and the termination of an oxygen enrichment (O2) procedure in the gas mixture which follows for the patient. If the error is not detected by the operator after the patient's aspiration maneuver and PEEP is set to a lower value of 4 mbar, patient hypoxia may occur, putting your life at risk. Although it is very difficult to happen, in the occurrence of the error, the patient may be put at risk. However, the corrective action that deactivates the function of the automatic suctioning maneuver is very simple and quick to execute, as well as verifying that the deactivation has taken place. Immediate action required of fan users: as soon as the suctioning maneuver is completed, the user must make sure that ventilation continues. If ventilation is interrupted, one of the following options can be used to restore ventilation: 1- Press the "Manual Breathing" button on the front panel of the ventilator, 2- Toggle the Ventilation Mode or 3- Activate the standby mode ( "Standby") and return to the previously set Ventilation Mode.
  • Causa
    Investigations have shown that ventilation and alarms of the hamilton-g5 pulmonary ventilator can be accidentally suppressed following the activation of a suctioning maneuver by the operator under a series of very specific circumstances. the ventilation should then be manually reactivated. the main cause, a synchronization problem of two program tasks processed simultaneously can result in fatal hypoxia in the patient.
  • Acción
    Field Correction (Deactivation of function that may cause the problem).
