Validation and Characterization of Signal Decrease on an Oximeter in Chronic Obstructive Pulmonary Disease

The objective is to verify that there is a decrease in the pulsed oxygen saturation with the digital sensor. That is, the drop in oxygen saturation in COPD patients during inhalation is real and not due to an artifact of the measuring tool, because oximeters need a quality pulsatile signal to properly measure oxygen saturation
