An oxygen cylinder assembly is depicted indoors in Kafr Sousa Municipality, Syria

An oxygen cylinder assembly is depicted indoors in Kafr Sousa Municipality, Syria. The main subject is a blue, metallic oxygen cylinder exhibiting significant wear, rust, and faded paint, with Arabic script handwritten on its surface. Attached to the cylinder's neck is a brass-colored main valve with a textured, possibly corroded handwheel. A regulator assembly is connected, featuring a circular pressure gauge displaying pressure in PSI and kPa, with its needle indicating a charge in the green zone (approximately 1000 PSI). Below this, a vertical transparent flow meter with LPM markings is visible, controlled by a blue knob labeled "SHUT OFF FLOW METER" and "OPEN." A clear plastic humidifier bottle, partially filled with water to just above the "LOWER" mark, is attached beneath the flow meter. Light blue plastic tubing, characteristic of a nasal cannula, is connected to the humidifier outlet and coiled around the regulator and cylinder. A red disc component on the regulator warns "USE NO OIL UNDER 1750 KPA (250 PSI)." The entire apparatus rests on a light-colored tiled or concrete floor. In the background, a light-colored staircase with multiple steps and a railing is visible, indicating an indoor, possibly residential or building common area setting. No people are present, and no actions or interactions are occurring.
