silhouette sign
peumonia
If lungs appear white on CXR
pneumonia
TB
mass
pleural effusion
If lungs appear black on CXR
pneumothorax
PE
IMaging of choice for lung after CXR
CT
H1 blockers
loratadine
diphenhydramine
cyproheptadine
alpha 1 agonist used for bronchodilation in asthma, nasal congestion
ephedrine
used in prophylaxis only for bronchial asthma
cromolyn sodium
rescue inhalers vs maintenance inhalers
rescue: sympathomimetics: epi, albuteroal, metoproterenol
maintenence: steroids (fluticasone), advair
chronic cough
> 8 weeks
three most common causes of chronic cough in non-smokers, not on ACEi
postnasal drip
asthma
GERD
what is a methacholine challenge used for
to diagnose asthma
wheezing, dyspnea, cough, nocturnal sx
asthma
DDX asthma
CHF PE GE reflux aspiration upper airway obstruction (tumor, etc)
decreased breath sounds with hyperresonance to percussion, shift of mediastinal structures on CXR
pneumothorax
absent lung sounds, dullness to percussion, mediastinal deviation toward affected side
atelectasis
most common pathogens for acute bronchitis
s. pneumonia

coccidiomycosis
chronic obstructive lung disease
airflow limitation from obstruction
overinflation of lungs
difficulty blowing air out
restrictive (interstitial) lung disease
infiltration of inflammation and scarring of lung parenchyma
lung fibrosis
smaller lung volume
difficulty getting air in
lower respiratory disease
bronchitis
emphysema
pink puffer normal CO2 permanent dilation of alveolar walls barrel chest pursed lips
emphysema
blue bloater increased pCO2 persistent cough with sputum > 2years obese cor pulmonale
Chronic bronchitis
If pH and PCO2 move in same direction
metabolic acidosis or alkalosis
