The SpO₂ value is often affected by the patient’s condition, artifacts created by external devices or by inappropriate attachment of probes, while monitoring continuously.
Nihon Kohden’s monitor has several features for better SpO₂ measurement. Let us introduce one of the features here: Response.
For other three features, please see in each page. Signal Quality Index, Pulse-amplitude Index, and Sensitivity Mode.

Our brochures and operation manuals indicate body weight of the patient as a yardstick when selecting a SpO₂ probe. We also state that an ideal thickness of measurement site is 6 to 18 mm in Case 2. Nonetheless, there are cases that it is difficult to stably measure an accurate SpO₂ value especially for neonates and infants.

Is there any official document or evidence evaluating the accuracy and the performance of Nihon Kohden probes?

How frequent should the probe attachment site and repositioning be checked?

There are some cases that are difficult to measure SpO₂ such as with restless patients due to body movement. In order to detect accurate and stable SpO₂ measurement, the probes should be attached in position.

How shall we select the measurement site? For Infant and Neonates?
Where shall we attach for patients who are difficult to measure with fingers/toes due to contraction of peripheral blood vessels or low perfusion?

What is SpO₂ measurement? What is the mechanism of SpO₂ measurement with a pulse oximeter?

Electrodes are attached correctly but the waveform shown on the display is not clear enough. It seems it has some kind of artifact.

Is there anything to be aware of, while recording ECG?

What is ECG? Where and how do we attach probes to patients to record clear ECG?

An incubator in NICU has a lot of moisture and fogging, it is difficult to monitoring CO₂ through a sampling tube for carbon dioxide.
Therefore transcutaneous Gas-Monitoring has been used in an incubator.
However that has also other risk of burn injury including cutaneous vesicles.

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

1. No portable CO2 monitor
2. Delicate and easy to break, and short lifetime
3. Long CO2 calibration 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 because of bulky size, dead space
