What does COPD stand for? What is a COPD Exacerbation? What is the medical definition of COPD? How can you treat a patient with COPD?
These are all common questions from students enrolled in certain medical school programs. COPD, or Chronic Obstructive Pulmonary Disease, is a disorder that affects millions of people around the world. As a Respiratory Therapist or medical professional, it’s an important topic that you must be very familiar with.
To help, we put this COPD study guide together in hopes that it makes the learning process a bit easier for you. So if you’re ready, let’s get started.

What Does COPD Stand For?
As mentioned in the introduction, COPD stands for Chronic Obstructive Pulmonary Disease. According to the CDC, it’s the third leading cause of death in the United States.
What is the Medical Definition of COPD?
COPD, or Chronic Obstructive Pulmonary Disease, is a chronic respiratory disease that causes progressive airway obstruction which results in breathing-related problems.
Two types of COPD include:
- Chronic bronchitis
What are the Causes of COPD?
The most common causes of COPD include the following:
- Cigarette smoking/tobacco
- Air pollution
In the United States, tobacco smoke is the leading preventable cause of COPD.
What is an Acute Exacerbation of COPD?
This could include noninvasive ventilation (BiPAP, CPAP, etc.) or intubation and conventional mechanical ventilation.
What is the Treatment for COPD?
The primary goal of treating COPD is to increase the patient’s life expectancy and quality of life while decreasing the number of COPD exacerbations and hospital visits.
Here are the General Steps for Treating COPD:
- Smoking cessation
- Disease management education
- Pulmonary rehab
- Avoid triggers and recurrent infections (such as the flu and pneumonia)
Next, we will discuss the treatment methods for COPD.
Methods for Treating COPD:
- Low-flow oxygen
- Bronchodilator therapy
- Preventative care
- Noninvasive ventilation (Preferred)
- Conventional mechanical ventilation
BiPAP (Bilevel Positive Airway Pressure) is preferred during an acute exacerbation of COPD in order to avoid intubation. However, if the patient’s condition worsens, intubation and conventional mechanical ventilation would be indicated.
What is CBABE?
CBABE is a mnemonic that can be used as a simple way to learn and memorize all of the obstructive diseases.
Just simply break it down and use each letter as follows:
- C – Cystic Fibrosis
- B – Bronchiectasis
- A – Asthma
- B – Bronchitis (Chronic)
- E – Emphysema
Again, you can easily memorize this acronym as a simple way to learn which disorders are classified as obstructive diseases.

Dyspnea, cough, sputum, fever, wheezing, chest tightness, and fatigue.
12. What are the differences on the major symptoms between chronic bronchitis and emphysema?
In chronic bronchitis, symptoms consist of excessive sputum production for at least 3 months for a year and twice in a row while emphysema’s symptoms consist of the destruction of the gas exchange surfaces.
13. What are two major ways to diagnose COPD?
Clinical assessment/history and Spirometer to measure volumes, capacities, and flow of air.
14. What are other ways to diagnose chronic obstructive pulmonary disease?

The Global Initiative for Chronic Obstructive Lung Disease (GOLD) staging systems are: Stage 1 or Mild COPD, patients with FEV1 (forced expiratory volume in one second) <80% of predicted. Patients experience shortness of breath when hurrying on the level or walking up a slight hill; Stage 2 or Moderate COPD, patients with FEV1=50-80% of predicted. Patients experience shortness of breath causing
