Rather than a blower I'm picturing a plastic bag pressed by a rolling cylinder at 5 or 10 seconds per cycle (normal breathing rate).
1) The roller pushes a single breath into the lungs. Air goes out a tube to the mask. (Add an oxygen feed if possible.)
2) As the roller returns to its original position, the bag fills with exhaled air. This gives a clue that the patient is breathing air out.
3) A valve activates, the roller pushes used air out of the bag to cleansing.
4) A valve activates, the roller returns to its original position as the bag fills with fresh air.

There are oxygen concentrators available for homebound respiratory patients. These are expensive new, but you might find a used one cheap. It may be an alternative to an oxygen tank.
