Healthy people hardly need it. These people can use oxygen generators: the elderly can take oxygen regularly after 60 years old, patients with cardiovascular and cerebrovascular diseases are suitable for oxygen health care, and brain users: white-collar workers, pregnant women: both the fetus and pregnant mothers need oxygen.
