Definition
The patient naturally purses their lips during exhalation because it
increases their positive end expiratory pressure allowing them to
breath out more air, decreasing air trapping and hyperinflation
Give this one a try later!
What systemic effects can occur as What effect does air trapping and
a result? gas exchange abnormalities have?
What is the main thing that leads to What benefits do pursed lips
COPD? provide?

What are some late stage physical signs and symptoms?
Give this one a try later!
1. Chronic inflammatory response Cyanosis/hypoxemic
2. Airflow limitation extremities; lips & fingertips
3. Progressive disease (along with clubbing)
4. Exacerbations and comorbidities
contribute Use of accessory muscles
Dyspnea: progressive & worse with
exercise 1. Airflow limitation & air trapping
2. Gas exchange abnormalities
Chronic cough: intermittent &
unproductive 3. Mucus hypersecretion
4. Pulmonary hypertension
Increased sputum production
5. Systemic effects
