The KONA system isn't an entirely new idea. Back in the 1990s we manufactured a similar device called the Orca. We've kept the same fundamentals, but we've added new features, new software, and streamlined the overall design. Take a look:


Breath-by-breath, O2, CO2, and respiration flow rate are measured precisely and accurately with internal sensors. Interfaces are provided for heart rate monitoring and pulse oximetry. The oxygen sensor is long-lasting and does not require routine maintenance.

Laser absorption spectroscopy oxygen sensor (fast response time and long life).
Non-dispersive infared CO2 sensor.


    Internal sampling pump and built-in proportional valve for precise flow control during breath-by-breath pressure changes.


Single-patient pneumotach use. Type in a calibration code into the software; no need for a 3L syringe
