Feedback:
Oxygen is necessary for anything to burn, and increasing oxygen allows common flammable materials to burn faster and hotter. Excess oxygen is not helpful; in fact, it can be harmful. Therefore, oxygen is prescribed as a medication and is administered under controlled conditions. When used properly, oxygen can decrease the heart's work of pumping blood and increased oxygen concentration can weaken the stimulus to breathe by affecting the ventilatory drive control mechanisms.
