Stage 4 emphysema is the most severe stage, in which a person's symptoms may significantly affect their quality of life. Although there is no cure for emphysema, treatments are available to help manage the symptoms and slow the progression of the disease.
The Global Initiative for Chronic Obstructive Lung Disease sets out the stages of COPD. Generally, the stages are based on a combination of airflow limitation, symptoms, and exacerbations. A doctor can use a breathing test to measure lung capacity. The test measures the forced expiratory volume in 1 second (FEV1).
Doctors describe this as stage 3 (severe) and stage 4 (very severe) emphysema. In these stages of the disease, the air sacs (called alveoli) in your lungs have serious, permanent damage. Instead of allowing you to exhale fully, the damaged air sacs cause air to get trapped inside the lungs.
Once emphysema advances to the severe stage, individuals may lose an average of 9 years of life expectancy. Various treatment options are available, with doctors reserving surgery for the most severe cases. Getting treatment early and quitting smoking can make a difference in a person's outlook.
When to use oxygen for emphysema. A doctor may recommend that a person begin using oxygen therapy when their blood oxygen saturation falls below 88% or their blood oxygen level falls below 55 millimeters of mercury (mmHg) at rest.
A person who receives a diagnosis of stage 4 emphysema can live for a decade or more following the diagnosis. The outlook is typically better for those who quit smoking and manage their symptoms well with medication.
Especially if your COPD is diagnosed early, if you have mild stage COPD, and your disease is well managed and controlled, you may be able to live for 10 or even 20 years after diagnosis.
"It's not a death sentence by any means. Many people will live into their 70s, 80s, or 90s with COPD.” But that's more likely, he says, if your case is mild and you don't have other health problems like heart disease or diabetes.
Symptoms of End-Stage COPD. Many of the symptoms you had in earlier stages, like coughing, mucus, shortness of breath, and tiredness, are likely to get worse. Just breathing takes a lot of effort. You might feel out of breath without doing much of anything.
Oxygen therapy can help people with severe emphysema that have low levels of oxygen in their blood to breathe better. The treatment involves administering oxygen either through a mask, or through two small tubes that enter the nose (nasal prongs).
Stage 4 is also called very severe emphysema. It can be particularly hard if you're 65 and older because breathing problems are more likely to interfere with basic daily tasks like dressing, cooking, or climbing stairs, and cause symptoms that send you to the hospital.
Because emphysema, like other forms of COPD, reduces the amount of oxygen that can reach your bloodstream, the heart works harder to spread oxygen throughout the body. A person with severe emphysema may get tired easily, may have chest pains or palpitations, or experience headaches, sleep problems, and irritability.
Emphysema usually progresses slowly and the majority of patients do not notice the changes in their breathing. Some patients do experience a faster onset of symptoms, though that is less common.
Emphysema continues to progress even after people stop smoking. However, quitting smoking helps reduce symptoms and improve quality of life and life expectancy.
Emphysema gets worse over time. You cannot undo the damage to your lungs. Over time, you may find that: You get short of breath even when you do things like get dressed or fix a meal.
Pulmonary emphysema usually occurs at 60 to 80 years of age, and is defined as being early-onset when the disease develops before 55 years of age (1). Not surprisingly, early-onset pulmonary emphysema is a rare condition.
Severe emphysema will, in most cases, be automatically approved for disability benefits if its effects reach the level of chronic obstructive pulmonary disorder (COPD).
Emphysema has no cure, and patients live with severe shortness of breath that makes daily activities like walking or showering difficult.
How Serious Is Your Emphysema? Stage 2 is also called moderate emphysema. But that doesn't always mean that your disease is moderate. If you're young and otherwise healthy, you could have severe lung damage and still be at stage 2.
You can't reverse your emphysema. But you can ease your symptoms and slow the progress of the disease.
COPD is terminal. People with COPD who do not die from another condition will usually die from COPD. Until 2011, the Global Initiative for Obstructive Lung Disease assessed the severity and stage of COPD using only forced expiratory volume in 1 second (FEV1).
Emphysema is a lung disease that results from damage to the walls of the alveoli in your lungs. A blockage (obstruction) may develop, which traps air inside your lungs. If you have too much air trapped in your lungs, your chest may appear fuller or have a barrel-chested appearance.
In the final days, the person with COPD may withdraw, not talking, eating, drinking or moving much. There may be changes in the breathing patterns, such as long pauses between breaths. The skin may become pale and cool.
