Case1 Difficulties with monitoring CO2

Even though monitorng CO2 is important and recommended by ASA/APSM Guidelines, we have a lot of difficulties as below:

  1. No portable CO2 monitors
  2. CO2 sensors are delicate and easy to break, and have a short lifetime
  3. Long CO2 calibration time and long warm-up
  4. Condensation or water trapped in sampling line
  5. Slow response, or long time to get results
  6. Difficult calibration 
  7. Not available for child patients because of bulky size and dead space

Our CO2 technology solves all these difficulties

  1. BSM-1700 series (Life Scope PT) and OLG-3800 (cap-TEN) are portable and measure CO2 parameter 
  2. Durable enough for use in harsh environments
    • The cap-ONE sensor is extremely light and compact, with a weight of 4 mg and a dead space of 0.5 mL with the infant airway adapter. Also, by using an anti-fogging membrane, neither a motor nor a heater is required. cap-ONE is highly durable, withstanding a drop test of 100 falls from a height of 2 m, a flex test of 5000 times with a 400 g load, and a water test with a 1 m submersion for 30 minutes (IPX-7). 
  3. No Calibration and No Warm-up
    • Nihon Kohden’s mainstream CO2 sensors have a dedicated airway adapters with a unique anti-fogging membrane and no heater. After connecting the CO2 sensor, you can start CO2 measurement in just 5 seconds with no calibration or warm-up time.
  4. Though typical membranes on adapter cause formation of water drops, our technology provides a reliable CO2 waveform even under high humidity conditions because of the state of the art technology of the anti-fogging membrane.
  5. Fast response with small lag time
  6. The CO2 sensor kit can be exposed to the air and calibrated easily with the connected airway adapter.
  7. cap-ONE performs with greater precision than side stream monitoring for nonintubated children (*1)
