The present invention relates to a sampling unit, a measurement system and method for transcutaneous blood gas measurements. In particular the invention relates to a sampling unit and system adapted for rapid measuring and monitoring of blood gases in a continuous gas flow. The sampling unit is provided with an ambient air inlet and a blood gas extraction and mixing chamber wherein air is mixed with extracted blood gases. The method of continuous transcutaneous measurement of carbon dioxide in the blood utilizes a pulsed heating to minimize the detrimental effects of the heating.

System and method for rapid blood gas monitoring

A miniaturized plasma source includes a stripline split-ring resonator. The split-ring resonator is sandwiched between two dielectric substrates and two metal ground planes. In order to make the plasma accessible from the outside of the ground planes, a hole is made through the gap between the ends of the split ring. The two ground planes act as an electromagnetic shield, protecting the split-ring resonator from electromagnetic interference due to changes in the electric or dielectric environment surrounding it. The miniaturized plasma source is particularly useful in optogalvanic spectroscopy applications.
