How would oxygen therapy help a patient who is having an asthma attack? what effect will it have on the patient?

Prevention: The respiratory system has an important roll in both providing oxygen to tissues & helping acutely regulate the delicate acid base balance in the body. Bronchospasm reduces the easy transfer of oxygen in & co2 out of the body.Without adequate o2, the body reverts to a metabolism that creates more acid causing deterioration, supplemental o2 helps avoid the acid buildup & nourishes tissues.

More oxygen delivery: In an acute asthma attack, there is not enough oxygen delivered to the body. That is why supplemental oxygen is helpful.
