Once the tube is in, you're managing two different problems. So keep them separate in your head.
Oxygenation is getting O₂ across the alveolar membrane and into the blood. You fix it with FiO₂, PEEP, and recruiting collapsed alveoli. You watch it with pulse oximetry.
Ventilation is moving CO₂ out of the body. You fix it with rate and tidal volume. You watch it with capnography.
A patient can fail one and look fine on the other. That's the trap. A sedated patient on high-flow oxygen can hold a saturation of 100% while hypoventilating into a dangerous hypercapnia. The oxygen reservoir masks the problem the pulse oximeter is measuring. So continuous capnography is standard on any sedated or ventilated patient, not just intubated ones.
