Chirana AURA V

Unique concept for unique solutions!

Chirana AURA V represents the highest level of ventilation system with above-standard ventilation modes for a variety of situations and for all ranges of patients. This is only one universal breathing unit which provides complete solution in basic equipment and it gives the priority to the efforts of patient to eliminate stress breathing. The advanced respiratory system is able to automatically compensate the dead space, compliance and resistance of breathing circuit. In-built artificial intelligence provides many automatic options including optimization of ventilation parameters based on on-line monitoring of breathing system mechanics what is resulted in better synchronization with patient and significant reducing of recovery time, elimination of potential complications and shorter weaning periods. The programmed multi-level ventilation mode using variable volume, variable pressure and variable time is unique method for ventilation of hardly damaged lungs from the pathology leading to inhomogeneous gas distribution (viral pneumonia, ALI, ARDS, contusion, etc.). The numerous features and functions are predetermined to deliver personalized, non-traumatic artificial ventilation adapted to the patient needs.

In previous waves of the COVID-19 pandemic, the high efficiency of the unique PMLV ventilation regime has been confirmed. In clinical practice, the treatment of COVID-19 (intubated patients) with a mortality of less than 20% has been achieved with the AURA V device using our recommended treatment methodology.
