    •  IngMar Medical is ISO/IEC 9001:2015 Certified (Registration Nr. 74 300 3727)
    • Our calibration lab is accredited to IOS/IES 17025:2005 (Certificate Nr. 4172.01)
    • The ASL 5000 meets or exceeds the requirements for test lungs used for volume testing as specified in the following standards:
      • ISO 80601-2-12:2011 (Critical Care Ventilators)
      • ISO 80601-2-13:2011 (Anesthetic Workstations)
      • ISO 10651-6:2004 (Home Care Ventilatory Support Devices)
      • ISO 10651-3:1997 (Emergency and Transport Ventilators).
  • Individual and sequential tests can be manually scripted or directly interfaced with LabVIEW-based or other test systems, for example to:
    • Cycle a ventilator through a production test sequence
    • Perform long term trouble shooting tests with trending of breath parameters
    • Develop adaptive algorithms on ventilators
    • Evaluate advanced respiratory modes, such as proportionally assisted ventilation
    • Evaluate performance parameters and ventilator/patient interaction
  • Computer controlled piston-cylinder unit unit (no springs or orifices) for precise programmable parameters that can be changed over time. See how it works.
  • Test Automation Interface – 
save time, accelerate development and achieve better control over testing protocols. Learn more.
  • Spontaneous breathing controls – simulate the spontaneously breathing patient in interaction with a ventilator.
  • Patient Model Library – quickly start running simulations with our library of over 35 preconfigured patient models (neonatal to adult).
  • Sophisticated modeling tools  define one- or two-compartment models, non-linear compliance and resistance effects.
  • Interactive control panel – adjust patient parameters on the fly while simulation is running.
  • Script editor – assemble and launch preconfigured breathing profiles. See how it works.
  • Simulate coughs and other extreme breaths. 
See how it works.
  • TCP/IP Broadcast – employ the integrated network data broadcast for importing data in realtime with a TCP/IP client (application language neutral).
  • High frequency (2 kHz) digital servo system and state-of-the-art brushless motor drive for smooth response to ventilator transients.
  • Post-run analysis – extensive data analysis package captures 90+ parameters for hours of trending and review, as well as flow, pressure, and volume waveforms. Export all captured data to ASCII (Excel-readable) formats with a mouse click. 
See how it works.
  • High accuracy flow measurement calculated from piston position eliminates the uncertainties of external flow meters.
  • Script progress display – check script duration (remaining, total) at any time.
  • 512Hz data sampling rate – conduct detailed analysis of ventilator triggering and other events.
  • Lightweight and portable – just 22 lbs (10 kg) for easy transport and use in multiple locations.
