REVIEW GRADED A+
◉ COPD. Answer: Diagnosis based on Hx of symptoms, physical
exam, chest imaging, pulmonary function tests and blood gas
analysis
Pulmonary function testing reveals airway obstruction (decreased
FEV1) that is progressive and unresponsive to bronchodilators,
Emphysema, Chronic bronchitis
◉ COPD Staging According to GOLD Guidelines- Based on degree of
airway limitation. Answer: Gold 1: Mild: FEV1≥80% predicted
Gold 2: Moderate: 50% ≤FEV1 <80% predicted
Gold 3: Severe: 30% ≤FEV1 <50% predicted
Gold 4: Very Severe: FEV < 30% predicted
◉ Emphysema. Answer: Damage occurs in the alveoli, Impairs gas
exchange, Issue is in expiration- they can get air in but cannot get air
out
Air trapping, Pursed lip-breathing
Increased A&P diameter, Barrel chest
, ◉ Chronic Bronchitis. Answer: Productive cough with copious
amounts of sputum
dyspnea
wheezing
rhonchi and cyanosis of the skin and mucous membranes
Damage occurs in the airway- not the alveoli, Mucous Plugs
◉ Forced Vital Capacity (FVC). Answer: Normal 80-120%
The FVC measures the volume of air in the lungs that can be exhaled.
Patient inhales as deep as possible and then exhales as long and as
forcefully as possible.
Obstructive: Will be decreased or normal
Restrictive: Will be decreased
◉ Forced Expiratory Volume in 1 second (FEV1). Answer: Normal
80-120%
Amount of air forcefully exhaled from the lungs in the first second.
