Q

Asthma

A
Steps:
1=PRN alb <2/wk, <2/mo
2=+low dose ICS 3-4/mo
3=+LABA OR +Med dose ICS daily, >1/wk
4=LABA AND med dose ICS >1/day
5=high dose ICS
6=+PO steroid

Exacerbation management
Mild-moderate=O2, SABA
Severe=O2, SABA+ipratropium, PO steroid, Mg if not improved in 1h, Look for signs of resp distress high PCO2, DECREASED wheezes
GERD can make sx worse 2/2 microaspiration! (Night + postprandial sx, hoarse in the AM)

Q

Congenital diaphragmatic hernia

A

Herniated gut compresses L lung, heart sounds louder on R, don’t do anything that will put air in the GI tract! ET intubation only, then NG decompression

Q

Pneumonia

A

V=0, severe V/Q mismatch, R—>L intrapulmonary shunting, NO IMPROVEMENT W INC FiO2

22
Q

PFTs

A

Obstructive: TLC ^ FEV1/FVC<80%, DLCO ^ in asthma, dec COPD
Restrictive: TLC dec, FEV1/FVC nl (both dec), DLCO dec ILD, nl restrictive chest wall dz

23
Q

Causes of cor pulmonale

A

COPD
ILD
Pulm vascular dz
OSA

24
Q

COPD exacerbation tx

A

O2
Neb albuterol + ipratropium (SABA + anticholinergjc)
PO steroid
+- abx
NO LABA FOR ACUTE EXACERBATION
In severe COPD, O2 can induce hypercapnea (VQ mismatch) May have sz

25
Chronic bronchitis vs emphysema
Chronic bronchitis—> productive cough 3 mo for 2 yrs, nl DLCO, CXR inc pulm vasc markings, flattened diaphragm Emphysema—> dec DLCO, CXR dec pulm vasc markings, hyperinflation, a-1-antitrypsin (liver dz, panacinar, lower lobes) vs smoking (centriacinar, upper lobe)
26
Cavitary lung lesions
1. Abscess—> usually anaerobes indolent course, SIADH, systemic sx, putrid sputum, upper lobes/posterior (dependent while lying down), alcoholic/drug user/chronic renal dz, CT air fluid levels clindamycin 2. Aspergillosis—> classic triad hemoptysis, pleuritic CP, fever, immunocomp, nodules w ground glass, chronic= >3 mo, systemic sx, cav lesion apical +/- aspergilloma 3. TB—> no air-fluid level, disseminated spondylitis/fx arthritis osteo 4. Bronchogenic carcinoma—> asbestos 5. Granulomatosis w polyangiitis—> ulcers, multiple, kidney probs 6. Squamous cell—> no leukocytosis or fever, slower onset (SMALL CELL DOES NOT FORM CAV)
27
Solitary pulmonary nodule
Def=<3cm, round, surround nl No change 2-3y r/o ca (ca x2 qmo-y) + changes—> CT serial scans, PET/bx (central bronchoscopy periph CT guided percutaneous), or if likely malignant surg
28
Secondary spontaneous pneumothorax
Ruptured apical bleb, COPD, Marfans, no tracheal shift
29
Massive hemoptysis
>600mL/24h or >1mL/h Bronchoscopy (balloon tamp, cauterize), pulm arteriography (embolization), thoracotomy if can’t stop bleeding Mild/mod can get a CT
30
Nonallergic rhinitis
No eye sx, no trigger | Tx intranasal antihist OR steroid
31
Croup
Barking cough, +\-insp stridor ONLY WHEN CRYING Steroid, racemic epi if no improvement Ddx DROOLING=epiglottitis (Hib)
32
Lung + kidney
Granulomatosis w polyangiitis—> tracheal narrowing, ulceration, multiple lung nodules w cavitation, anemia, dx ANCA or bx, tx steroid + rituximab OR cyclophosphamide Goodpasture—> basement membrane
33
COPD diaphragm flattening
INC wob (shortened muscle can’t contract as well during inspiration) INC lung compliance INC thoracic wall recoil
34
Aspirin-exacerbated respiratory disease
Looks like asthma sx + allergic eyes, 30m-3h after NSAID, dec PGE, inc leukotrienes, polyps
35
Sarcoidosis
Looks like mediastinal widening on XR, chronic granulomatous inflammation
36
If it’s a euvolemic patient w lung stuff literally ANY lung stuff + hyponatremia
SIADH
37
ARDs
``` O2 doesn't help Lung compliance IS LOW (fluid) PaO2/FiO2 DEC Aa gradient INC PA pressure INC ```
38
