The image shows a green-colored medical device, which appears to be a ventilator, attached to a white wall. The device is made of plastic and has a cylindrical shape with a nozzle at the top. The nozzle has a small hole in the center, which is likely used to connect the ventilators to the wall. On the left side of the device, there is a small green cap with a threaded end. The cap is attached to the top of the nozzle with a white cord. The background is plain white.
