Chirana AURA Basic

Unique concept for unique solutions!

Chirana AURA Basic is intended for long-time intensive therapy. There is option of controlled, supporting or spontaneous lung’s ventilation for both children and adult patients including automatic compensation of death space of breathing circuit. The colour 15” touch display and intuitive user interface allows really easy adjustment of basic ventilation modes and their modifications. This breathing unit is independent from central supply of compressed air or from external compressor. The inbuilt multi-membrane air generator delivers constant flow of pressured air in all of requested levels of working pressure and is designed for very long lifetime (above 50000 hours of operation). Optional possibility of low-pressure O2 connection from oxygen concentrator makes Chirana AURA Basic very variable and widely applicable solution even in very hard conditions.

Ventilation modes:

  • CMV - continuous mandatory /mechanical/ ventilation 

  • SCMV - synchronized continuous mechanical ventilation 

  • PC V - pressure controlled ventilation 

  • SPCV  - synchronized pressure controlled ventilation

  • SIMV(V)+PS – volume controlled artificial inspirium with pressure support

  • SIMV(P)+PS – pressure controlled artificial inspirium with pressure support

  • PS – pressure support

  • APRV (BIPAP) – airway pressure release ventilation

  • 2-Level – two level ventilation (Bilevel, BiPAP, DuoPAP)

  • 2-Level+PS – ventilation at two pressure levels with pressure support at both pressure levels

  • CPAP – continuous positive airway pressure

  • MVs (APMV) – minute ventilation servo (automatic proportional minute volume)

  • MLV – multi-level ventilation

  • CFS - Continuous Flow support

  • SIGH – sigh (deep breath)

  • PS-VG - pressure support volume guaranted called PS-CMV.

  • PC-VG- presssure control volume guarranted

  • SIMV-VG - synchronized intermittent mandatory ventilation volume guarranted

  • BIPAP (2LV)-VG - two level ventilation volume guarranted

  • PMLV®-VG - programmed multi level ventilation volume guarranted

Monitoring the mechanical properties of the lung on-line:

  • Time constant period of inspirium and expirium,

  • peak alveolar pressure,

  • alveolar pressure of end-tidal PEEP,

  • alveolar pressure

  • Auto PEEP,

  • static lung compliance,

  • dynamic lung compliance.

  • inspiration resistance of airways and  ventilation system 

  • There is implemented a three-tier system of alarms

  • Alarm system works through sound and light signals to the display and remembering causes

  • sophisticated system for extreme situations, allowing when you enter the patient's weight, to make a quick start appliance in ventilation modes CMV

  • Integrated electronic multimembrane air generator or turbine (optional) provides increased protection against hypoxic mixture

  • Secure Electronic Control FiO 2

  • If oxygen supply failed, the device makes ventilation with AIR from the environment

  • The minimum period of internal battery - 240 min

  • adopted for connection with O2 concentrator
