After the publications of NOTT and MRC trial, long-term oxygen therapy has been accepted as an important and necessary treatment regime in COPD patients with severe resting chronic hypoxemia. Appropriate evaluation of oxygenation status helps to select the right candidate to have this therapy. Setting the proper treatment goal is based on the individual patient's need. The three major delivery systems for the long-term home oxygen therapy are compressed oxygen in tanks, liquid oxygen, and oxygen concentrators. Each system has its own advantages and disadvantages. The choice of any system for individual patient must be based on relative cost, portability, and safety features. The three commercially available means for improving oxygen-delivery efficiency are the transtracheal catheter, the reservoir cannula, and the demand oxygen delivery system. Each method is designed to reduce oxygen wastage during exhalation and each has its own advantages and drawbacks. Careful instruction, close supervision, and periodic re-evaluation and instruction are essential to improve patient's compliance, to reduce the incidence of complications, and to obtain the optimal benefit.
