Different stages. If you are at a critical stage where you can't breath for yourself, a ventilator does the work for you.
If you can breath for yourself, but your lungs have become inefficient at absorbing enough oxygen from regular air, then providing more oxygen rich air helps you keep your blood oxygen level up.
If boris is just getting oxygen and not a ventilator, that's a good sign that he is more alive than dead.
