Nebulizer is just room air (which is 21% Oxygen, 69% other gases) pushed by a compressor fan quickly which makes the medicine placed into nebulizer unit turn into droplet particles due to vibration from fast air passage in unit. --you get 21% O2 .
Nasal Canula's can deliver much higher flow rates"

During an acute Asthma flare, airwys constrict severely with Some episodes resulting in hypoxea, so supplemental Oxygen helpful. Mainstay is bronchodilators: Albuterol, Atrovent and steroids: IV solumedrol. If hypoxea is a re-ocurring problem, Mom might need small portable O2 tank at home in case of emergency's. Most insurance won't pay for prn useage, but a small E tank can usually be rented for $35.00/month + cost of refill when needed---Sometimes just having this in the home brings piece of mind.

Info on Home O2 setups:
Oxygen concentrators concentrate oxygen from the air and deliver it to the patient. This is not portable and requires electricity to work. Portable E tanks are also delivered for transport and may be used for backup in case of power failure. Oxygen concentrators are often used for individuals who are on oxygen only at night but can be used 24 hours per day.
Liquid oxygen systems consist of a large silver main tank and one or two portable units. The portable units are used as needed for travel outside of the home. When they are empty, they can be refilled from the large tank. Liquid oxygen will evaporate if not used frequently and Needs to be kept cooled. to prevent combustion.
