Optimizing Patient Care

Integrated Monitoring

Monitoring of a patient's cardiorespiratory status is essential for optimal outcomes. Seamless integration of end-tidal CO₂, volumetric capnography and SpO₂ monitoring in the NKV-550 Series Ventilator System help the clinician optimize ventilator settings and assess changing patient conditions. Having a fully integrated suite of monitoring tools helps reduce the need to purchase additional equipment to be placed at the already-crowded bedside.


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) non-invasively 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.

Patient Comfort

  • Comfortable fit and light weight for patient satisfaction with highly reliable measurement
  • SpO₂ sensor with stabilizing clamp on the sides to prevent accidental removal to reduce technical alarms
  • The multi-site sensor can be used for neonate foot as well as adult fingers
  • The finger-tip sensor covers less area of the finger and gives the patient more freedom for finger movement

Clinical Application

  • It's unique design improves comfort to the patient by providing an optimal distribution of pressure
  • Bright LED technology provides more accurate measurement for thicker fingers or skin with darker pigmentation
  • The reusable sensor has a specially designed clamp to prevent accidental fallout or removal of the sensor, leading to reduced technical alarms
  • The BluPRO technology in SpO₂ sensors gives high accuracy even during movements

Uniqueness Of The cap-ONE CO₂ Sensor

A new class ultra-compact and highly durable CO₂ sensor.

Nihon Kohden's cap-ONE employs advanced miniaturization of infrared absorption spectroscopy system and its sensor has achieved an extremely light and small size with a weight of 4 g with the dead space of 0.5 mL. Also, by using an anti-fogging membrane, a motor and heater are not required. This results in a sensor that is about 80% lighter and 90% smaller than typical CO₂ sensors.

The highly durable cap-ONE, withstands a drop test of 100 falls from a height of 2 m, 5,000 flex tests with a 400 g load and a water test 30 minutes.
