5. Conclusions
Near-infrared tissue spectroscopy is a non invasive, innocuous technique to measure oxygen saturation in tissues. NIR oximetry can be used in almost any area of the body, according to the type of analysis to be done.
The development of a laser oximeter, more selective and closer to the requirements of the diffusion theoretical model allows to better evaluate the oxygen saturation from the intensity of the backscattered light at two different wavelengths; the use of a fibre optic probe provides a flexible mechanical connection between the spectroscopic device and the patient, cutting any electrical contact.
From the safety point of view, the system has been calibrated following the CEI EN 60825-1 standard and classified as a Class 1 system.
Preliminary tests performed on volunteers have shown that CW laser oximeter can easily real time follow variations of the biological tissue oxygenation.
