The appearance of the device does indeed resemble an ordinary pillow, but that’s probably where their similarities end. An oxygen pillow is a rectangular rubber container with a volume of 10-75 liters, equipped with a mouthpiece (or, alternatively, a funnel) and a rubber tube with a valve that regulates the supply of therapeutic gas. Oxygen is pumped into the pillow from a cylinder, to which a reducer is first attached to reduce the pressure to 2 atm. The doctor writes a prescription, and then you can go to a specialized pharmacy or to the polyclinic at the patient’s place of residence for the device. The pillow is designed for multiple use, and as the oxygen mixture is consumed, the container can be refilled by contacting a pharmacy or medical institution.
