Monitor your Patient with Reliable cap-ONE Mainstream CO2 Sensor

cap-ONE is Nihon Kohden’s unique mainstream CO2 sensor for both intubated and non-intubated patients. The ultra-compact sensor and unique adapter provide accurate measurements and reduces the burden on the patients.

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

Ultra-compact and lightweight

The size of the sensor part was reduced about 90% and the weight was reduced to about 4g to realize an ultra-compact lightweight sensor that reduces patient burden and enables stability of the breathing circuit. This ultra-compact size and lighter weight was achieved by sophisticated production techniques and seasoned production staff using a microscope for all bonding of miniature components. Printed circuit boards receive work by hand to individually fold them in the sensor component. Nihon Kohden’s advanced production technologies supported the miniaturization of cap-ONE.

Robust impact resistance

Innovative sensor components and sensor structure have realized impact resistance and peace of mind even if the sensor is dropped. The sensor has passed the MIL standard (US Department of Defense Standard) impact test. This is an assessment standard for products used in harsh environments such as outdoors. The sensor also passed drop tests based on in-house standards that are higher than those used for our previous products.

Superior CO2 measurement can be used on smaller size newborns

The smaller sensor needs a lower volume of exhaled gas than conventional sensors. This allows CO2 measurement of smaller newborn infants who have lower exhalation volume.

By using with a cap-ONE mask, CO2 can be measured during oxygen administration

In addition to the cap-ONE CO2 sensor, Nihon Kohden also developed the cap-ONE mask which is an oxygen mask that allows simultaneous CO2 measurement. The following features expand the possibilities for CO2measurement.
