In order to keep hose for oxygen delivery off of the floor and thus make use of the oxygen delivery system safer, a storage system for storing the hose includes a support structure, a first pulley assembly, and a second pulley assembly below the first pulley assembly. At least a part of the first pulley assembly is translationally fixed relative to the support structure, and the second pulley assembly is translationally movable relative to the first pulley assembly, along the support structure. The hose is wrapped around pulleys of the first pulley assembly and pulleys of the second pulley assembly, and the amount of hose stored in the storage system is dependent on a position of the second pulley assembly relative to the first pulley assembly.
