Severe COPD will reduce the lungs' ability to put oxygen into the blood to be carried throughout the body. An elderly person's doctor can measure the oxygen in the blood by using a pulse oximeter. This is a small device that fits snugly on the finger. It measures how many red blood cells are carrying oxygen. If the level of oxygen in the blood is too low, it can be confirmed by an arterial blood gas test (ABG). If so, your doctor may prescribe oxygen therapy.
Oxygen Therapy for COPD
Shortness of breath does not necessarily mean you need to be on oxygen. Many people who have severe shortness of breath do not have low oxygen levels in there blood. Also, many patients who have low oxygen levels do not always feel breathless. Oxygen is usually ordered if the oxygen in the body or blood is low during sleep, exercise, during a 6-minute walk test and/or while you are not active.
Oxygen is a medical treatment. It requires a doctor's prescription that will describe exactly how much oxygen is needed for different activities such as exercise and sleep. It is very important to use the amount of oxygen ordered. A respiratory therapist can help you learn exactly how to use oxygen. (Oxygen supply companies may provide a respiratory therapist.) There are several types of oxygen systems. There are many factors that help the doctor decide which system is right for you. These include how much oxygen is needed, when it is needed, the person's daily activity level, where the person lives, the total cost of the system, and what medical insurance the person has.
Pulmonary Rehabilitation
Pulmonary rehabilitation is a treatment program. It provides exercise training, education about COPD, tips on how to complete everyday activities without becoming so short of breath and advice on how to live better with your disease. Many different types of medical professionals work with you in the program. These include doctors, nurses, physical therapists, exercise specialists, and dietitians. Dieticians are individuals who can teach you about healthy food choices. You will work with this team to create a special program for you. Pulmonary rehab programs are available in most communities and often paid for by insurance.
