Q

Features of emphysema?

Study These Flashcards
A

AP diameter, pink puffer, pursed lips, prolonged expiratory phase.

23
Q

Features of chronic bronchitis/

Study These Flashcards
A

Hypoxia, pulmonary constriction. Pulmonary hypertension, RH failure, edema. Copious mucous

24
Q

How to dx emphysema?

Study These Flashcards
A

PFT with decreased FEV/FVC ratio, no change with bronchodilator, no provocation with methacholine. CXR is nonspecific but shows hyperinflation, flat diaphragm

25
How to treat COPD
Corticosteroids | O2 Start with pa02
26
How to work up COPD exacerbation?
S/s COPD exacerbation? CXR, EKG, ABG. | Then give duonebs q30x3 with a goal spo2 of 88-92.
27
When to move COPD patient to ICU?
If severe acidosis.
28
When to send COPD patient home?
If stable, give doxycycline or fluoroquinolone.
29
When to send COPD patient to wards
In between. Give scheduled nebs, PO steroids. ABX; doxycycline.
30
Sxs of lung cancer?
Fever, weightloss, hemoptysis
31
PFTs for muscle weakness
Like restrictive pattern but residual volume is huge.
32
If lung mass is peripheral and high risk, how to work up?
Percutaneous ct guided biopsy
33
If lung mass is central and high risk how to work up?
Bronch or EBUS
34
Ph of transudate, exudate, empyema?
Transudate = 7.45-7.55 Exudate = 7.3-7.4 Empyema
35
How to work up pleural effusion
Get upright and lateral decubitus images. If it doesn't layer, then loculated. If 1cm ask if CHF, if CHF, then diurese. If not, do a thoracentesis and test for transudate or exudate.
36
How to work up pulmonary nodule?
Get a CT scan, if lesion is
37
Small cell carcinoma
Central, lots of paraneoplastic syndromes like ACTH, ADH, Lambert eaton syndrome. Treat with chemo
38
Squamous cell carcinoma
Central, can cause PTHrP and hypercalcemia, caused by smoking.
39
Adenocarcinoma
peripheral mass, no paraneoplastic syndrome
40
Carcinoid
Fluishing, diarrhea, LH fibrosis. Get 5HIAA to assess
41
PFTs for interstitial lung disease
Decreased FEV1, very decreased FVC so ratio increased or normal.
42
PFTs for muscle weakness
Like restrictive pattern but residual volume is huge.
43
What causes exudates, what causes transudates?
``` Exudates= malignancy, pneumonia, TB Transudates = CHF, nephrosis, gastrosis, cirrhosis ```
44
How to distinguish pleural exudate vs transudate
Light's criteria: Exudate if LDH >2/3 ULN LDHf/LDHs >.6 Protein F/ Protein S >.5
45
Ph of transudate, exudate, empyema?
Transudate = 7.45-7.55 Exudate = 7.3-7.4 Empyema
46
How to work up pleural effusion
Get upright and lateral decubitus images. If it doesn't layer, then loculated. If 1cm ask if CHF, if CHF, then diurese. If not, do a thoracentesis and test for transudate or exudate.
47
ARDS
Noncardiogenic pulmonary edema. O2 is diffusion limited, CO2 is perfusion limited.
48
How does a patient get ARDS?
Gram negative sepsis, TRALI, near drowning.
49
How to diagnose ARDS?
CXR- bilateral fluffy infiltrates.
50
PCWP and LV function in ARDS vs CHF?
PCWP normal in ards, same with Lv function | In CHF, PCWP increased, LV function decreased.
51
How to distinguish ARDS from CHF with lab values
BNP
52
How to treat ARDS
Fix underlying disease, add steroids. | PEEP ventilation with decreased tidal volume
53
ABG in PE?
Decreased PaO2, decreased PaCO2 (due to perfusion limited diffusion), so pH increases
