Software version 3.20 is available for DrÃ¤ger Medical's Carina ventilator. It provides more support for non-invasively ventilated patients and helps to reduce the therapy effort. An extended alarm management allows Carina to minimise unnecessary alarms. Thus, the equipment helps to support the success of the non-invasive ventilation (NIV) therapy.
With software 3.20 Carina offers an activatable pressure support for the controlled ventilation modes pressure control-biphasic positive airway pressure and pressure control-synchronised intermittent mandatory ventilation. Through this additional function the ventilator recognises when the patient is able to breathe again and actively supports this. This is particularly useful during the weaning process to fully restore the sponteanous breathing of the patient at the end of mechanical ventilation.
The ventilator does not only react sensitively to spontaneous breathing of the patient. In addition, with the AutoAdapt function, Carina can help the patient to get used to breathing pressures slowly. This helps to improve tolerance and cooperation of the patient. Patients who are awake often perceive the use of a mask with full breathing pressure as uncomfortable. Thus, often the doctor or nurse initially sets the pressure level on a low level, to gradually increase it during the ventilation process. Since this has so far been happening manually, a frequent back and forth to and from the ventilator has been unavoidable. AutoAdapt automatically completes this task after a configuration of the start settings and a selected adaption time between five and 120 minutes, which may reduce the therapy effort. Through the new Auto wake-up function the patient may, even after a long interruption, start the equipment from standby mode with the first breath and continue with the ventilation therapy. The equipment does not have to be restarted manually for this.
The alarm management of the Carina software 3.20, which has been specifically adapted to the NIV requirements, can reduce warning signals to what is strictly medically necessary. The consideration behind this is that frequent false alarms do not only put an unnecessary burden on medical personnel, but may also worsen patient motivation for the therapy. The SyncPlus-functionality of the Carina which continually compensates the varying leakages, supports in reducing additional alarms.
