Japan has opened a temporary facility in Tokyo to provide oxygen for up to 130 coronavirus patients with mild symptoms, as the capital’s health care system grows severely strained.

The so-called “oxygen station” in Tokyo’s Shibuya district is aimed at people who develop a problem while isolating at home or waiting for hospital vacancies, and is staffed by three doctors and 25 nurses, according to an AP report.

The idea is to temporarily treat mild cases with supplementary oxygen amid growing concerns that people may get sicker — and possibly start dying at home — in the absence of medical attention.
