Summary

The goal of this observational study is to find out if researchers can measure oxygen consumption in the body without having to draw blood from lines in arteries and central veins. Participants will undergo measurements of arterial blood oxygen saturation using both finger and neck pulse oximeters.

Detailed description

TOUCAN-1 is a study to estimate the accuracy and precision of pulse oximetry as a noninvasive tool for oxygen consumption measurement. Researchers will use a pair of commercially-available, noninvasive pulse oximeters to estimate the oxygen saturation of blood in the internal jugular vein, and compare it to the directly measured oxygen saturation in sampled jugular blood. Researchers will then measure the arterial oxygen saturation in a finger, and compare it to the directly measured oxygen saturation in sampled radial arterial blood.

Conditions
