The principle of pulse oximetry was developed by Nihon Kohden researcher Takuo Aoyagi in the early 1970’s. Pulse oximetry measures blood oxygen saturation (SpO2) noninvasively with an infrared sensor on the fingertip. Before that, the measurement of blood oxygen saturation required arterial blood sampling. Thanks to pulse oximetry, the critical parameter of SpO2 can be measured painlessly, continuously and in real time.

Nihon Kohden developed the world's first mainstream CO2 sensor that is specifically designed for non-intubated patients. This sensor attaches to a disposable oral and nasal adaptor and is placed directly at the point of expiration. Using advanced miniaturization and sensor technology, we have created an extremely small and lightweight sensor that is more comfortable for the patient.

Nihon Kohden is Japan’s only developer and manufacturer of biphasic type defibrillators. We have also developed our own proprietary defibrillation technologies. Nihon Kohden introduced its first AED in 2009 and continues to promote the spread of AED in order to contribute to increased survival from sudden cardiac arrest.
