The document discusses COPD (chronic obstructive pulmonary disease), its causes, symptoms, differences from asthma, classifications, treatments, and management. It provides information from Dr. Mohammad Zannatul Rayhan on COPD, including that it is a lung disease caused by chronic interference with lung airflow and impairs breathing. The major cause of COPD is smoking. Treatments discussed include bronchodilators, anti-inflammatory drugs, oxygen therapy, pulmonary rehabilitation, and smoking cessation.

3. COPD
COPD is a lung disease caused by
chronic interference with lung airflow
that impairs breathing, and is not fully
reversible
Usually symptoms- shortness of breath,
recurrent coughing, clearing throat, and
progressive exercise intolerance,
worsen over time
Many doctors and researchers consider
terms such as chronic bronchitis and
emphysema as forms of COPD
The major cause of COPD is smoking
4. Asthma
It is a respiratory condition
marked by spasms of the
bronchi, due to inflamed
and narrowed
It causes difficulty in
breathing that often results
from an allergic reaction
Asthma usually causes
recurring periods of
shortness of breath,
wheezing and/or chest
tightness
5. Similarities between
COPD vs. asthma
Coughing
Shortness of breath
Chest tightness
Exercise intolerance
Wheezing
Anxiety with increased heart rate may
occur in both diseases.
6. Differences between
COPD vs. asthma
In asthma, breathing can return to normal between attacks,
while breathing with COPD usually does not return to normal.
The symptoms of COPD gradually become more severe
COPD produces more mucus and phlegm compared to asthma
Chronic cough is common with COPD
People with COPD often have chronic blueness to fingernail
beds and/or lips
Asthma can occur in a person of almost any age, while COPD
usually occurs in those over age 40
7. Asthma - COPD Overlap (ACO)
Feature ACO
Age of onset Usually age ≥40 years, but may have had symptoms in childhood or early adulthood
Pattern of respiratory
Symptoms
Respiratory symptoms including exertional dyspnea are persistent but variability may
be prominent
Lung function Airflow limitation not fully reversible, but often with current or historical variability
Lung function between
symptoms
Persistent airflow limitation
Past history or family
history
Frequently a history of doctor-diagnosed asthma (current or previous), allergies and
a family history of asthma, and/or a history of noxious exposures
Time course Symptoms are partly but significantly reduced by treatment. Progression is
usual and treatment needs are high
Chest X-ray Similar to COPD
Typical airway
inflammation
Eosinophils and/or neutrophils in sputum
8. Classification of COPD
In patients with FEV1/FVC<0.70:
GOLD 1: Mild FEV1 > 80% Predicted
GOLD 2: Moderate 50% < FEV1 < 80% Predicted
GOLD 3: Severe 30% < FEV1 < 50% Predicted
GOLD 4: Very Severe FEV1 < 30% Predicted

12. Other Pharmacological Treatment
Alpha-1 Antitrypsin Augmentation Therapy
Intravenous augmentation therapy may slow down the progression of
emphysema
Antitussives
There is no conclusive evidence of a beneficial role of antitussives in patient with
COPD
Vasodilators
Vasodilators do not improve outcomes and may worsen oxygenation
13. Oxygen therapy and Ventilator
support in Stable COPD
NPPV may improve hospitalization-free survival in selected patients
after recent hospitalization, particularly in those with pronounced
daytime persistant hypercapnia (PaCO2 > 52 mmHg)
Long term administration of oxygen increases survival in patients
with severe chronic resting arterial hypoxemia
In patient with stable COPD and moderate resting or exercise-
induced arterial desaturation, prescription of long-term oxygen
does not lengthen time to death

15. Pulmonary rehabilitation, self-management
and integrative care in COPD
Pulmonary
Rehabilitation
Education and
Self-
Management
Integrated care
programs
Pulmonary Rehabilitation improves dyspnea, health status and exercise
tolerance in stable patients
Pulmonary Rehabilitation reduces hospitalization among patients who have
had a recent exacerbation (<4weeks from prior hospitalization)
Pulmonary Rehabilitation leads to a reduction in symptoms of anxiety and
depression
Education alone has not been shown to be effective
Self-management intervention with communication with professional improves
health status and decrease hospitalizations and emergency department visits
Integrative care and telehealth have no demonstrated benefit at this time
