PULMONOLOGY Flashcards
Top Causes of Chronic Cough
Upper Airway Cough Syndrome
Asthma
PTB
GERD
How to diagnose asthma?
History of variable symptoms
FEV1/FVC < 0.75-0.80
Reversibility Criteria
- reduced FEV1 that increases by >12% and by at least 200ml post bronchodilator or after 4 weeks on steroid trial
- decrease in FEV1 by 20% with metacholine or histamine
Asthma Hallmark
Airway hyperresponsiveness
Major risk factor for asthma
Atopy
Most common allergen
dust mite
Most accurate test in diagnosing asthma
Pulmonary Function Test or Spirometry
How long should cough be to be considered CHRONIC?
> 8 weeks
Most accurate test in asymptomatic patient
Metacholine/histamine stimulation test
First Line of treatment for asthma
INHALED CORTICOSTEROIDS
Patient has been having DAILY symptoms of asthma and gets awaken at least once a week by it. What will you give?
Medium dose maintenance
ICS formoterol
Patient has asthma symptoms MOST DAYS and at least once a week awakens with asthma. What will you give?
Low dose maintenance
ICS Formoterol
ACUTE SEVERE ASTHMA.What will you give?
SABA
Salbutamol q15 3x then q4
SABA
salbutamol
Albuterol
Terbutaline
LABA
Salmeterol
Formoterol
Indacaterol
Anti-IgE
Omalizumab
Asthma drugs safe for pregnant
SABA, ICS, THEOPHYLLINE
PREDNISONE
Most accurate test for COPD
Pulmonary Function Test
Most common risk factor COPD
Smoking
OTHERS
- airway hyperresponsiveness
- infections
- ambient air pollution
- smoking exposure
Classic Symptoms of COPD
dyspnea
chronic cough
chronic sputum production
COPD HALLMARK
airflow obstruction
Spirometry criteria for COPD
FEV1/FVC ratio < 0.7
Lung Pattern: Restrictive
Restrictive=Right
Smaller and displaced to the right
decreased volume
GOLD CLASSIFICATION
1 - FEV1>=80%
2 - FEV1 50-79%
3 - FEV1 30-49%
4 - FEV1 < 30%
3 Interventions demonstrated to improve survival in COPD
smoking cessation
O2 therapy
Lung volume reduction
When to start supplemental O2?
PO2<55 or sat <88% at room air
PO2<60 AND with signs of pulmonary HTN/erythrocytosis
Pharmacotherapy for smoking cessation (3)
Nicotine, Bupropion, Varenicline
5As in Smoking Cessation therapy
Ask Advise Assess Assist Arrange
Acute COPD exacerbation treatment
immediate nebulization + bronchodilators Antibiotics Glucocorticoids (Prednisone) NIPPV Intubation
Most common cause of CAP
Streptococcus pneumoniae
CAP in a patient staying on a cruise ship for 2 weeks. Etiology?
Legionella
Patients with stroke, dementia, decreased consciousness developed CAP. Etiology?
Anaerobes, Gram (-) enteric bacteria
Patient with recent antibiotic use, malnutrition, steroid use, bronchiectasis developed CAP. Etiology?
Pseudomonas
Best initial test for CAP
CXR
