Which is better to use diffuse oxygen supply or oxygen inhalation at plateau?

Decentralized oxygen supply is more convenient. A room is equipped with an oxygen generator, which can provide oxygen for a large number of people without wearing a mask or a nasal catheter. However, the disadvantage is that due to the large indoor space, the inhaled oxygen concentration is lower than that of the mask or nasal catheter. The advantage of wearing a mask or nasal catheter directly is that the oxygen concentration is high, but the disadvantage is that it is inconvenient and the number of oxygen feeders per machine is small. Decentralized oxygen supply can be divided into centralized decentralized oxygen supply (somewhat similar to central air conditioning, except that oxygen comes out) and split decentralized oxygen supply (suitable for horizontal and other single rooms). The cost of decentralized oxygen supply is higher than that of oxygen inhalation machine, but it is more practical. Both the office and the home can be used. The source of oxygen in Tibet has helped many families and units to install decentralized oxygen supply machines in Plateau, so that offices and families are no longer deprived of oxygen.
