A pulse oximeter measures the body's oxygen saturation with a small clip.

oxygen, carbon, hydrogen, nitrogen, phosphorous, and calcium.
oxygen and nutrients
because it is a tactical procedure
without nitrogen our bodys would over oxygenate (get to much oxygen). nitrogen is important for plants, after all they breath in nitrogen and breath out oxygen.
Respiration supplies the body with oxygen, energy could be a byproduct because you need oxygen to perform tasks that create energy
Aerobic exercise basically mean that you're working out at a rate that lets your lungs(and heart) keep up with your bodys need of oxygen. There's anaerobic exercises as well, during which you push really hard for a short time and deplete your bodys store of oxygen in the tissues. Then you have a recovery period and then you push ard again.
The respiratory and cardiovascular systems work in tandem to provide oxygen to the body's cells.
