A variety of conditions can lead to airflow obstruction, including inflammation and scars. Chronic airflow obstruction is a specific syndrome, and it is more severe than chronic bronchitis or emphysema.
At least two thirds of patients presenting to an ENT or ENT/laryngology (ENTL) practice have airflow obstruction, which is associated with significant morbidity and substantial costs. The differential diagnosis of AAFO should be improved.
A persistent cough is the most common symptom, and is often the initial sign of airflow obstruction. Other symptoms relate to the intensity of the cough and the amount of sputum produced. Coughing can also be a sign of airway obstruction, and the presence of sputum can often be an indicator of the presence of lung disease. However, in the absence of a history of cough of long duration, lung nodules or emphysema are suggestive of airflow obstruction, and in the absence of cough, the chest X-ray may reveal abnormalities in the lung parenchyma.
There is no evidence in the current literature supporting the thesis that airflow obstruction, chronic is actually cure or that it is even possible to permanently eliminate symptoms through medical management of airflow obstruction.
The treatment of choice for chronic airflow obstruction depends on the severity of the symptoms and the functional disability it causes. Common treatments include inhalation of oxygen alone, a low-dose ciclosporin (CyC) treatment, and a combination of CyC and ciprofloxacin.
About 1.2 million people will be diagnosed with airflow obstruction, chronic in the United States in 2024, and one-half the people will receive COPD-specific treatment.
Palliative care consultations on acute palliative care consult day 2, and day 4 in the dying patient seem to have a clinical effectiveness; thus an early palliative care consultation (within the first 24 hours post admission) does not seem to be indicated. This was indicated by the high percentage of patients' selfreported comfort and symptom relief.
Results from a recent clinical trial are encouraging, and may in time lead to greater palliative care provision to those previously overlooked in care plans and services. While some limitations to this study exist, the findings suggest early palliative care consultations may improve quality of life of patients with advanced disease, warrant further investigation.
Early consultation in a patient with advanced cancer before dyspnea is present is not necessarily in the patient's or their family's interest. It is often in the physician's. Early and timely palliative care consultation seems to lead to less aggressive symptom management, enhanced quality of life, improved outcomes including symptom relief and increased length of survival even after first-line treatment.
Most patients with chronic airflow obstruction suffer from serious consequences, including chronic bronchitis and emphysema, and this may be due to long sitting in a squatting position during work. Those with COPD-related airflow obstruction should be encouraged and supported to improve their walking capacity with and without exertion, as well as to lose weight and decrease the risk of comorbid and potentially serious medical complications.
Age is not the only factor related to airflow obstruction. The average age of onset in women was approximately 15 years earlier than in men. The reasons for this may include an earlier exposure to the agent causing the pathophysiology, women being exposed to more occupational and environmental hazards, and women developing airflow obstruction later than men. These observations may also suggest that lung function declines over a relatively longer period in women than men.
Since a combination of bronchodilators has been the most commonly used treatment, it seems prudent to consider this approach first when trying to treat COPD patients in the emergency department.
