Pulmonology Flashcards
Asthma Dx Tests
PFTs,
FEV1/FVC decreased
Reversible and inducible
Asthma Presentation
Wheezing, SOB, Cough
Asthma, Atopy, Allergies
Hyperresonance
If asthma suspected with normal PFT what do you do
Methylcholine challenge test
If asthma is suspected and PFT is abnormal what do you do
Give albuterol, if there is improvement asthma is confirmed
Asthma Category 1, Intermittent
daytime-<2/wk
Nighttime-<2/month
FEV1-80%
Asthma Category 2, Mild Persistent
daytime-<1/day, >2/wk
Nightime-<1/wk, >2/mon
FEV1-80%
Asthma Category 3, Moderate Persistent
daytime->1/day
Nightime->1/wk
FEV1-60-80%
Asthma Category 4, Severe Persistent
daytime->1/day
Nightime-Frequent
FEV1-<60%
Asthma Category 5
Refractory, requires oral steroids
Asthma Category 1 Tx
Short acting Bronchodilator- Albuterol
Asthma Category 2 Tx
SABA + Inhaled Corticosteroid (-asone)
Asthma Catgory 3 Tx
SABA + ICS or LTA + LABA
Asthma Category 4 Tx
Increase the dose of the ICS
Lung Cancer Work up
- CXR
- CT SCAN
- Biopsy
Lung CA Biopsy methods
Bronchoscopy- when the mass is in the bronchus
CT guided percutaneous-when the lesion is peripheral
VATS when the lesion is in the middle of the lung
Who needs Lung CA Screening
Low dose CT scan yearly
Age 55-80
30 pack year history
quit smoking <15 years
Pulmonary nodule, probably benign
<8mm, smooth, no smoking, calcified, age <45
Pulmonary nodule, Probably malignant
> 2 cm, Spiculated, Smoking, Age >70
Pulmonary Nodule Workup
- Check old films, see if size has changed
Small Cell Cancer
Location
Paraneoplastic syndromes
Tx
Central
AcTH (Cushing)
SIADH
Chemo/radiation
Squamous Cell CA
Location
Paraneoplastic Syndromes
Tx
Central
PTHrP- causes hypercalcemia
Resection, then chemo/radiation
Adenocarcinoma
Location
Pathology
usually non-smokers or those exposed to asbestos
Peripheral
Carcinoid
Serotonin syndrome
5HIAA in the urine
flushing, wheezing, diarrhea
LIGHTS CRITERIA
LDH >2/3 Upper limit of normal
LDHf/LDHs >0.6
TPf/TPs >0.5
if any are positive it is an exudate
causes of transudative pleural effusion
CHF, Nephrosis, Gastrosis, Cirrhosis,
Causes of exudative pleural effusion
Malignancy, Pneumonia, TB
Elevated ADA in pleural effusion
Tuberculosis
Pleural Effusion Workup
1. Imaging Lateral decubitus x-ray US CT 2. Septations present-thoracostomy fails thoracotomy
Pleural effusion with CHF
Diuresis first if that fails then thoracentesis
When is V/Q Scan used in PE
If patient has a normal chest x-ray and abnormal kidneys
When do you use IV contrast CT
Normal Kidneys
COPD Management
Corticosteroids ICS, Oral, IV
Oxygen keep O2 sat 88-92, given if SpO2 <88% PaO2 <55
Prevention
Dilators-short acting, long acting, oral
Experimental
Rehab
COPD Treatment
SABA as needed, then LAMA (Tiotropium), LABA (olol), ICS, PDE4 Inhibitors, Steroids
COPD Exacerbation workup
CXR, ABG, ECG
COPD Exacerbation Tx
Antibiotics: Doxycycline, Azithromycin
Bronchodilators: Albuterol, Ipratropium
ARDS, what is the PCWP & LV Fxn
PCWP-Normal
LV Fxn-Normal or increased
ARDS Patient
Very sick patient as in
Septic shock, TRALI, Near drowning
P/A <200
CXR- pulmonary edema
ARDS Tx
Intubation
ARDS Ventilator settings
CO2- Low Tidal Volume
High Respiratory Rate
PEEP
Interstitial Lung Disease Pt Hx
Chronic, Insidious

24-48 hrs after exposure, then resolves after being away from exposure for 24-48 hrs
