Study Notes

Classifications of Asthma

Four primary classifications: Intermittent, Mild persistent, Moderate persistent, Severe persistent.
Classifications assess Severity based on two domains: Impairment and Risk.

Impairment

Measures asthma's current impact on quality of life and functional capacity.
Reflects how symptoms affect daily activities and normal lung function.

Risk

Addresses potential future complications from asthma, including exacerbations and progressive lung function decline.

Intermittent Asthma

Symptom frequency: Occurs 2 or fewer days per week.
Nighttime awakenings: 2 or fewer times per month.
SABA (Short-Acting Beta-Agonist) use: 2 or fewer days per week.
Impact on normal lung activity: None experienced.
Lung function tests:
- Normal FEV (Forced Expiratory Volume) between exacerbations.
- FEV greater than 80% of predicted values.
- Normal FEV/FVC (Forced Vital Capacity) ratio.
Initial treatment recommendation: Step 1.

Mild Asthma

Symptom frequency: More than 2 days per week but not daily.
Nighttime awakenings: 3 to 4 times per month.
SABA use: More than 2 days per week but not daily, with a maximum of once per day.
Lung function tests:
- FEV greater than 80% of predicted values.
- Normal FEV/FVC ratio.
Initial treatment recommendation: Step 2.

Moderate Asthma

Symptom frequency: Experiences symptoms daily.
Nighttime awakenings: More than once a week but not every night.
SABA use: Required daily to manage symptoms.
Lung function tests:
- FEV between 60% and 80% of predicted values.
- FEV/FVC ratio reduced by 5%.
Initial treatment recommendation: Step 3.

Severe Asthma

Symptom frequency: Symptoms present multiple times throughout the day.
Nighttime awakenings: Often occurs nightly.
SABA use: Several times per day to maintain control.
Lung function tests:
- FEV less than 60% of predicted values.
- FEV/FVC ratio reduced by 5%.
Initial treatment recommendation: Step 4 or 5.
