What are the differences between a home oxygen concentrator and an oxygen generator in a hospital? To put it simply, the oxygen equipment in a hospital is of professional grade, with high purity, large oxygen output, absolute stability, complete and reliable accessories, strict safety standards, and is used for severe treatment. While a home oxygen concentrator is an auxiliary tool, mostly of a health care level, with a purity of 30% to 90%, small oxygen output, simple design, and convenient operation, suitable for daily oxygen supplementation. The two cannot replace each other. Let's elaborate: The purity of oxygen output between hospital oxygen generator and home ones is different. The oxygen production system in a hospital is very strict, It can usually stably produce oxygen with a purity of more than 93%, and even reach 99.5% through purification equipment. Such high-purity oxygen can be directly used for surgeries of severely ill patients. While home oxygen concentrators are mostly of a health care level, with oxygen output purity ranging from 30% to 90%, mainly for people with mild hypoxia, such as elderly patients with asthma for daily oxygen supplementation, or to alleviate altitude sickness during high-altitude travel,cannot be used directly for severe illness treatment. Moreover, the stability of oxygen output between hospital oxygen generator and home ones is not at the same level. Hospital oxygen production systems are large, like a small oxygen factory, capable of continuously producing oxygen 24/7, with large oxygen output, able to supply the entire department or even the entire hospital, with stable pressure and flow. Even if there is an increase in oxygen demand due to emergency patients, it can withstand. While home oxygen concentrators are small power units, with smaller oxygen output, usually only suitable for one or two people, and are limited by the size of the machine, they may heat up after continuous operation for a long time, and the flow fluctuation is also slightly larger, making them more suitable for short-term, low-intensity use.
