Oxygen Queue The sharp increase in the number of corona patients in Mashhad and the filling of all hospital beds has caused a large number of patients with Covid-19 to spend difficult days of treatment at home using oxygen capsules. Oxygen capsules are hard to find in Mashhad these days, and citizens pay about 3 million tomans ($111) to buy a 10-liter capsule and at least 50,000 tomans ($1.85) to rent it daily. 10-liter oxygen capsules have a maximum oxygen consumption of about 5 hours. Due to the lack of charging centers and the long distance to the center of Mashhad, many people around and families of patients have been forced to visit these centers several times and stand in long queues. Some of these centers are working 24 hours a day, and several centers have been established by people as a charity and are providing services to patients suffering from Corona. 15 August 2021, Mashhad, Iran
