PRÉCISE 3000 - The oxygen-conserving system

PRÉCISE 3000, the oxygen-conserving system – safe, economical and accurate Conventional systems administer a preset bolus of oxygen (oxygen quantity) for each breath taken. Even if the user draws deeper breaths, e.g. under strain, the oxygen quantity administered remains the same for each inhalation, thus reducing the concentration of oxygen in the lungs.


This process actually counteracts the body’s natural oxygen requirement. With PRÉCISE 3000 the oxygen supply is matched to the user’s requirement thanks to the AO2D system (automatic O2 dosage). The result for the user: more effective supply combined with lower costs!


  • Huge conservation of oxygen, even with differing      levels of strain
  • More mobility
  • More independence
  • More quality of life for the patient
  • Less mucosal irritation and reduced risk of infection
  • Even smaller, even handier, even lighter, even clearer
  • First device with AO2D (automatic O2 dosage)
  • First device with EA (sensitivity adjustment)
  • Individual fine tuning
  • First device to feature alphanumeric character display
  • Safety devices to countervail human error
  • Extensive security and alarm functions
  • Compatible with all O2 supply systems, incl. liquid oxygen systems
  • Maintenance-free technology
  • Comfortable transport systems: shoulderbags, rucksacks,  caddies

lower costs combined with optimum supply.
It is a well-known fact that the human lung’s primary source of O2 is the first part of inhalation. A special sensor detects this exact time and enables the O2 supply to be tailored to the user’s requirements.

Thanks to its intermittent flow system PRÉCISE 3000 conserves approximately 80% more oxygen than devices with a continual O2 flow.



  • Battery low indication
  • Visual warning of insufficient oxygen supply
  • Acoustic warning of insufficient oxygen supply
  • Alarm triggered if no pulse registered on inhalation
  • Excess supply prevented by 40 inhalations/minute limit
  • Automatic switch-off function after four minutes (if user has forgotten to switch off the device), thus conserving oxygen and preventing unnecessary battery consumption.
