CAPNOSTAT® Mainstream
The Revolutionary CAPNOSTS CO2 Sensor has no moving part

An advanced development team at Respironics has made dependable mainstream CO2 monitoring a reality with the invention of the solid state CAPNOSTAT.

Key elements of the Respironics solid state design:

  • A patented IR source capable of being pulsed on and off very rapidly, which eliminates the need to interrupt the IR beam with a rotating chopper wheel.
  • A beam splitter allows a single beam infrared pulse to simultaneously strike reference and measurement detectors, replacing a sealed gas reference cell rotating on a chopper wheel. Since reference and measurement signals occur at precisely the same time, changes in the optical signal due to contaminants in the airway are effectively removed from the signal. This results in superior performance under adverse clinical conditions.

The resulting rugged design allows the CAPNOSTAT to withstand the demands of the harsh hospital environment.

Initial CO2 indication in just 15 seconds

In addition to being extremely rugged, the CAPNOSTAT can display a capnogram 15 seconds after power-up and is fully operational within an additional 15 seconds.
