Advanced Chronic Obstructive Pulmonary Disease (Stage 4): Indicators, Outcome, and Additional Information
Chronic Obstructive Pulmonary Disease (COPD), including emphysema and chronic bronchitis, is a progressive condition with four stages. End-stage COPD, or very severe COPD, is the most severe stage, characterized by significantly reduced lung function where even daily activities can cause breathlessness and fatigue.
Bullectomy, a surgical procedure, involves the removal of one or more bullae from the lungs, which are large, damaged air sacs that can expand and stop air from moving in and out of the lungs. Lung volume reduction surgery, on the other hand, removes the most diseased portion of the upper lung tissue, allowing the healthier part of the lungs to work better. In some cases, a lung transplant may be an option for people with end-stage COPD if lung damage can't be repaired, if they've had three or more severe exacerbations within the past year, or if they aren't a candidate for lung volume reduction surgery.
Treatments for end-stage COPD include medications, pulmonary rehabilitation, and oxygen therapy. Bronchodilators, which help to widen airways, and glucocorticosteroids, which help reduce inflammation in the airways and lungs, are common medications used to treat COPD and relieve symptoms. A spacer, a small plastic tube that attaches to an inhaler and helps ensure the medication gets deep into the lungs, and a nebulizer, a machine that turns a liquid medication into a continuous mist, are often used to administer these medications. Supplemental oxygen is typically needed for end-stage COPD and involves receiving oxygen to increase the amount of oxygen that flows into the lungs, helping to make breathing easier.
In addition to receiving treatment, there are lifestyle changes that can be made to help manage the symptoms of end-stage COPD. Avoiding smoking, exercising, eating a balanced diet, avoiding triggers, preparing for extreme weather, conserving energy, finding support, and practicing palliative care are all important steps. For caregivers, helping the loved one breathe easier, managing loss of appetite, easing pain, finding ways to conserve energy, addressing emotional needs, looking into palliative or hospice care, preparing for emergencies, planning for end-of-life care, and asking for help when needed are essential tips.
The Global Initiative for Chronic Obstructive Lung Disease (GOLD) guidelines are used to help determine COPD stages. The GOLD criteria uses FEV1 results to grade COPD as follows: mild (≥ 80%), moderate (50-79%), severe (30-49%), and very severe (< 30%). In addition to FEV1 results, the 2023 GOLD guidelines use symptom severity and number of exacerbations to further categorize people with COPD into groups labeled A, B, or E.
When planning for end-of-life care, it's important to talk with loved ones and healthcare team about medical choices, complete an advance directive, and consider questions such as where end-of-life care will be received, when to stop receiving treatment, and who will make healthcare and treatment decisions if unable to do so. Seeking palliative or hospice care can provide comfort and help manage symptoms of end-stage COPD.
In conclusion, while there's currently no cure for COPD, understanding the disease and its stages, making necessary lifestyle changes, and seeking appropriate treatments can help manage the symptoms of end-stage COPD and improve the quality of life for those affected.
