Some people definitely benefit from oxygen during exertion, but others are disappointed to find they do not. If a benefit is demonstrated, it is recommended that you use your oxygen 'as needed', which means during any activity which normally causes you to become short of breath. If no benefit is demonstrated with oxygen, remember that there are many other causes of breathlessness besides a low oxygen level. The most common method of oxygen delivery nowadays is the oxygen concentrator . This electrically driven machine concentrates oxygen from the air through a fine sieve.
Electricity is used for many hours in the day from a standard power point.
Cost rebates may be available through your local electricity supplier if you are a pensioner or a veteran. These machines provide the amount of oxygen needed to reverse the low blood oxygen levels. They do not remove oxygen from a room any more than an adult would by simply breathing from the same room air. Added oxygen is usually delivered into the nose through soft plastic prongs attached to tubing which fits onto the outflow port of the concentrator. Long lengths of tubing enable you to move around your house more freely while wearing the nasal prongs.
