Details and patient eligibility

About

This study aims at validating new optical transcutaneous sensors to evaluate tissue capnia (CO2 partial pressure) and oxygenation (blood oxygen saturation) by comparing them to standard laboratory measurements (end tidal CO2 measurements and oxygen saturation by near-infrared spectroscopy).
