The method for measuring the concentration of blood gases such as oxygen and carbon dioxide in arterial blood differs from the method in which all the blood in the artery is removed and directly measured. A transcutaneous blood gas concentration measurement method is already known, which captures blood gas on the entire skin surface and enables continuous measurement over time without causing any pain to the patient.

Now, a contact liquid 12 is interposed between the sensor and the skin, a double-sided adhesive disk 13 with a hole in the center is placed in close contact with the skin surface 14, and the temperature of the constant temperature heating mechanism is adjusted to 4.
When set at 3 to 44C, the skin in contact with this will be heated and the subcutaneous tissue will be arterialized.

Therefore, the oxygen concentration within the tissue becomes substantially equal to that contained in arterial blood, and this oxygen diffuses throughout the skin tissue, permeates the entire membrane, and further diffuses through the electrolyte to reach the cathode. At this time, if a polarization voltage necessary for the reduction reaction of oxygen is applied between the cathode and anode, the surface of the cathode (platinum or gold) will be 02+4H++4e → 4H20 (in case of acidity).

As a result, an electrolytic current flows between the electrodes, but this current is proportional to the number of oxygen molecules that permeate the membrane, completely diffuse in the electrolyte, and reach the cathode, and therefore the oxygen gas concentration at the membrane surface. By performing all measurements, it is possible to approximately measure the oxygen concentration in the subcutaneous tissue and therefore in the arterial blood.

The oxygen concentration rapidly decreased from point A, but this was because the skin surface completely blocked air, and the oxygen in the electrolyte was consumed at the cathode, causing the oxygen concentration to gradually decrease. The oxygen concentration reaches its minimum at point B and gradually increases thereafter. From point B onward, arterialization of the subcutaneous tissue progresses, indicating that oxygen diffusion increases throughout the subcutaneous tissue. At point C, y
Arterialization is achieved and oxygen diffuses throughout the tissue.
Is the progress from reaching a steady state to the point determined by transcutaneous measurement of changes in blood oxygen concentration inside the living body? This is what is shown.

The above example shows the results of measurements made using all conventionally used adhesive discs, and the time it takes to achieve arterialization, that is, the time from point A to point C in Figure 1. It lasts a long time. The time for arterialization varies greatly between subjects, but it is usually 15 to 30 minutes for newborns and 30 minutes to 30 minutes for adults.
It takes about 50 minutes in total. As mentioned above, generally when the skin heating mechanism of the sensor causes total arterialization of the subcutaneous tissue, Ki,
The time required for arterialization is relatively long. This problem is common not only to blood oxygen concentration sensors, but also to general transcutaneous blood gas concentration sensors such as blood carbon dioxide concentration sensors.Is this an emergency? This is extremely inconvenient when measuring a large number of patients in a short period of time.

FIG. 3 shows, as an example, an adhesive disc containing all nicotinic acid amide among the vasodilators (1% cotinic acid amide). All of the examples are shown in which measurements were taken on the same subject as in the example shown in Figure 1, and the time required for arterialization was significantly shortened compared to the previously used adhesive disc, and in the above example, is shortened by y3AVc. Furthermore, the duration of the effect of vasodilators is relatively short.
Most of the effects disappear after about 30 to 40 minutes, and arterialization is continued thereafter due to heating by the skin heating mechanism.
