Long-Term Oxygen Therapy Delivery Systems

Abstract

Three major systems are currently available in most urban settings for the delivery of long-term oxygen therapy. These are compressed oxygen in tanks, liquid oxygen, and oxygen concentrators. Each system has advantages and disadvantages. The choice of system for any individual patient must be based on relative cost, the need for portability, and safety features. The cost of oxygen and regulations governing its reimbursement vary widely throughout the country. Oxygen should be supplied by reputable vendors who meet specific criteria for assuring quality service. In many instances referral to a home care agency for teaching and supervision of the patient is essential. Patient compliance with long-term oxygen therapy is often poor due to factors such as lack of significant subjective improvement, unrealistic fears or embarrassment concerning use of oxygen, and feelings of depression or hopelessness that the patient may experience when told he needs oxygen.
