IHT
has become popular in Russia and Ukraine, and special devices have been
developed for its administration. One of the most important aspects of
such devices is accurate and dependable measurement of oxygen partial
pressure in expired air while transcutaneously measuring oxygen partial
pressure (PO2)
in arterial blood. Two novel elements of this work are (1) the
application of pulse methods of oxygen sensor polarization in the
technology for
optimal PO2
sensor design and (2) improvement of processing output signals to
improve the
metrological characteristics. Application of this novel
polarization method causes minimal sensor influence on the steady-state
processes in biological objects, thus increasing the measurement
accuracy and ensuring prompt reaction of the device to changes in
external factors. Owing to high operation speed, the device can be used
for measuring lung ventilation parameters and blood vessel response to
irritation. In using pulse polarization techniques, an optimal device
design, device-manufacturing technology, and a relevant mathematical
processing of measurement results is selected. The apparatus has the
potential to be widely used in many areas of experimental and clinical
medicine that require PO2
values.
