The function of oxygen:
1. Supplying oxygen to patients can assist in the treatment of heart
head blood-vessel, respiratory system, such as chronic obstructive
pneumonia disease, rehabilitation and hypoxia conditions.
2. Oxygen could improve body function, especially suit for elderly,
pregnant women, physique, students etc. Who got physiological
hypoxia. It may also reduce fatigue after heavy manual or mental
consumption.
