What is cap-ONE?

The best way to observe the patient's respiratory conditioncap-one_logo.png

Optional capnography for both ingubated an non-intubated patients with cap-ONE 

cap-ONE is Nihon Kohden's unique mainstream CO2 sensor for both intubated and non-intubated patients. 
Ultra compact sensor and unique adapter provides accurate measurements and reduce the burden on the patients.

cap-ONE overcomes the disadvantages and maintains all the advantages of mainstream sensor for the optimal capnography.


A new class ultra compact and highly durable sensor

cap-ONE employs advanced miniaturization of infrared absorption spectroscopy system, the cap-ONE sensor has achieved an extremely light and small size with a weight of 4 mg and the the dead space of 0.5 mL. Also, by using anti-fogging membrane, neither motor nor heater is required. 

cap-ONE is highly durable - withstands a drop test of 100 falls from a height of 2  a flex test of 5000 times with a 400 g load, and a water test with a 1 m for 30 minutes (IPX-7).

cap-ONE unique design

Two measuring methods - Quantitative method (TG-980P):
Quantitative method cancels the affect of the factors that cause inaccurate measurement such as deterioration of light source, dirty windows of the sensor, and water drops in the airway adaptor. So it can provide reliable measurement even under high humidity conditions.
Two measuring methods - Semi-quantitative method (TG-920P): 


Semi-quantitative method assumes inspired CO2 as 0 mm Hg, so it does not require user calibration. It requires fewer parts which lessen the posibility of malfunction.

Innovative features - Anti-fogging membrane

cap-ONE uses the original transparent film with anti-fogging membrane. The anti-fogging membrane forms a smooth layer of water which allows stable transmission of infrared light without irregular reflection. This technology eliminates the need of heaters and reduces power consumption and weight of the cap-ONE sensor.
