COPD Stages
Many physicians classify COPD into stages, which can help provide a better understanding of the severity or progression of your disease. While COPD stages are not an official medical diagnosis, they can help you and your doctor decide the best course to treat your COPD.
Doctors use the GOLD (Global Initiative for Chronic Obstructive Lung Disease) system to identify COPD stages based on:
- your symptoms;
- spirometry test (measures lung capacity) results;
- whether your COPD has gotten worse over time;
- number of hospital stays related to COPD; and
- other conditions that might make COPD worse, such as diabetes, heart disease, or high blood pressure.
Once your doctor takes all these things into consideration, they may tell you that you fall into one of these four stages:
- Stage 1: During this mild stage, you may experience no symptoms or a few symptoms such as some shortness of breath during heavy exercise or after walking upstairs.
- Stage 2: During this moderate stage, you may experience some shortness of breath while walking and have to stop every few minutes to catch your breath.
- Stage 3: This severe stage causes significant shortness of breath, even during daily activities like getting dressed.
- Stage 4 (end-stage COPD): This very severe stage of COPD is likely accompanied by other conditions, such as lung failure or heart failure. You may experience shortness of breath all the time, even while resting.
COPD Diagnosis
Pulmonology specialists at U of U 亚洲自慰视频 use several diagnostic tools and tests to identify COPD stages, which will help determine your best COPD treatment options.
Your doctor may recommend one or more of the following tests after discussing your symptoms and doing a physical exam:
- spirometry,
- CT scan,
- chest X-ray,
- to determine whether you have alpha-1-antitrypsin deficiency (a genetic disorder that can lead to COPD).
Laboratory tests may also be used to rule out other conditions with symptoms that are similar to COPD.
What Is a Spirometry Test?
Spirometry tests are used to measure lung capacity by determining:
- how much air you inhale,
- how much air you exhale, and
- how quickly you exhale.
Your doctor will use a spirometry test if they think you have COPD or another chronic lung disease, such as asthma. Doctors also use spirometry tests after your diagnosis to determine how well medications or other treatments are working, and whether the condition is getting worse.
During a spirometry test, your doctor will place a clip on your nose to make you breathe through your mouth only. While seated, you will take a deep breath and blow out as hard and as fast as you can into a tube. You will repeat this three times.
The device measures:
- Forced vital capacity (FVC) 鈥 How much air you can exhale after taking in a deep breath
- Forced expiratory volume (FEV) 鈥 How much air you can force out of your lungs in one second.
Your doctor will use the highest FVC and FEV results. Lower-than-normal results for FVC, FEV, or the relationship between FVC and FEV, can be a sign of obstructed breathing in your lungs due to COPD or another condition.
Symptoms of End-Stage COPD
A person with stage 4 COPD, or FEV levels that are below 30 percent, has end-stage COPD. It鈥檚 the most advanced form of the disease.
Symptoms of end-stage COPD are similar to the symptoms for other stages, but often more severe. These include:
- severe limits to your physical activity,
- extreme shortness of breath,
- blue-tinted skin as a result of low oxygen levels,
- confusion or memory loss from oxygen deprivation,
- frequent lung infections,
- more frequent or more severe COPD exacerbations and flare-ups,
- trouble eating and swallowing,
- muscle wasting (a loss of muscle mass) and weakness,
- anxiety, and
- depression.

Risks of End-Stage COPD
A person with end-stage COPD will have difficulty getting enough oxygen to their body from their lungs. When that happens, they鈥檙e at higher risk of severe or life-threatening conditions, including:
- very low blood oxygen levels (hypoxemia),
- low oxygen levels in body tissues (hypoxia),
- chronic respiratory failure,
- buildup of carbon dioxide in your body, or
- failure of the right side of the heart.
Treatment for End-Stage COPD
It is difficult to treat end-stage COPD. Some patients can benefit from lung volume reduction treatment therapies. Others with end-stage COPD might be eligible for a lung transplant, but that is something you will need to discuss with your doctor.
For many patients, end-stage COPD treatment includes palliative care to manage pain and difficulty breathing, and assist with daily living activities. This type of care does not treat the underlying COPD condition. Options for palliative care include:
- anxiety or depression medication;
- complementary therapies, such as yoga or massage;
- assistance with activities like getting dressed or cooking; or
- hospice care.
