C) Wall outlet unit
D) Concentrator
D
Feedback:
Oxygen concentrators are widely used in home and extended care settings. They compress room air and extract oxygen, providing concentrated oxygen flows in the range of 1 to 5 liters per minute (LPM). An oxygen concentrator is much safer and more convenient to use than an oxygen tank. It also does not need to be refilled. Some large facilities have a hyperbaric chamber, which simulates deep sea diving by increasing atmospheric pressure. Careful handling and use of oxygen cylinders is necessary because the gas contained within a cylinder is under extremely high pressure and the pressure must be reduced to a safe level before the cylinder is connected to a person. Wall outlets are used in large healthcare facilities with bulk storage and in-room piping systems.
