The patient receives continuous oxygen with a nc at 2 L/min using an oxygen concentrator. The patient states that when traveling in his car, he uses an E cylinder secured in the back seat of his car and a spare cylinder in his truck for especially long trips. The RT should explain the proper method of cylinder transport and inform him that - ✔✔-He should not transport the spare cylinder in the trunk, but secure it in the backseat of the car the Rt is making a routine visit to the home of a 62 year old patient who receives continuous oxygen through a nc at 2 L/min using an oxygen concentrator.
