Pulmonology

Question 1

Asthma Severity Intermittent: Daytime symptoms, nighttime awakenings, lung function, exacerbation

Answer 1

Daytime symptoms: <=2 days/week
night awakenings
Age 0-4: 0
Age >=5: <=2x /month
Short acting beta-2 agonist use for symptoms (not for prevention of exercise induced bronchospasm: <=2 days/week
Interference with normal activity: none
FEV1 % predicted, age >=5 years : Normal FEV1 between exacerbations; >80% predicted
FEV1:FVC ratio (age 5-11): >85%
FEV1:FVC ratio (age>=12): Normal
Exacerbations requiring corticosteroids
Age 0-4: 0-1 /year
Age >=5: 0-1/year

Question 2

Asthma Severity Persistent-Mild: Daytime symptoms, nighttime awakenings, lung function, exacerbation

Answer 2

Daytime symptoms: <=2 days/week but not daily
night awakenings
Age 0-4: 1-2x /month
Age >=5: 3-4x/month
Short acting beta-2 agonist use for symptoms (not for prevention of exercise induced bronchospasm: >2 days/week but not daily, and not more than 1x on any day
Interference with normal activity: minor limitation

FEV1 % predicted, age >=5 years : >=80% predicted
FEV1:FVC ratio (age 5-11): >80%
FEV1:FVC ratio (age>=12): Normal

Exacerbations requiring corticosteroids
Age 0-4: >= 2 exacerbations in 6 months requiring systematic corticosteroids, OR >=4 wheezing episodes/year lasting >1 day and risk factors for persistent asthma
Age >=5: >=2 /year

Question 3

Asthma Severity Persistent-Moderate: Daytime symptoms, nighttime awakenings, lung function, exacerbation

Answer 3

Daytime symptoms: Daily
Nighttime awakenings:
Age 0-4: 3-4x /month
Age >=5: >1x / week but not nightly
Short acting beta-2 agonist use for symptoms (not for prevention of exercise induced bronchospasm: Daily
Interference with normal activity: Some limitation

FEV1 % predicted, age >=5 years : 60-80% predicted
FEV1:FVC ratio (age 5-11): 75% to 80%
FEV1:FVC ratio (age>=12): Reduced 5%

Exacerbations requiring corticosteroids
Age 0-4: >= 2 exacerbations in 6 months requiring systematic corticosteroids, OR >=4 wheezing episodes/year lasting >1 day and risk factors for persistent asthma
Age >=5: >=2 /year

Question 4
