PI is an indicator of the relative strength of the pulsatile signal from pulse oximetry and has been found to be a reliable indicator of peripheral perfusion. PI is calculated by dividing the pulsatile signal (AC) by the nonpulsatile signal (DC) times 100, and is expressed as a percent ranging from 0.02% to 20%.

Why am I short of breath but my oxygen saturation is good?
Shortness of breath does not always indicate that you are hypoxic. In other words, your level of dyspnea, or air hunger, does not always correlate with your oxygen saturation. This means that you can be short of breath, even extremely short of breath, even in the presence of normal oxygen saturation.
Does deep breathing increase oxygen blood?
Slow and deep breathing increases the level of oxygen in our blood. Oxygen is transported to the blood within the body through the respiratory system and that is why it influences your oxygen level if your breathing is not optimal.
