Q

How do we diagnose asthma?

A

Do a pulmonary function test. If it shows obstructive with the ratio being reduced then this is an abnormal test. Then try to rescue them with broncho dilator and if they are reversed, they have asthma. If the PFT is normal, try to induce them with methyl choline. If you cause them to have asthma, they have it.

Q

When can someone be sent home vs. sent to ICU for an asthma attack?

A

Don’t need 02, are not wheezing and PEFR is over 70%

O2 need is rising, build up of co2, and PEFR is less than 50%

Q

Why do we want to keep COPD folks at 88-92 oxygen?

A

Their Respiratory drive is driven by hypoxia and not hypercapnia, so we want their o2 a little lower to help with that.

25
patho, location, 2 paraneoplastic syndromes, and treatment of small cell?
smoking, centrally (trachea and bronchi), ACTC and SIADH, chemo and radiation
26
patho, location, 1 paraneoplastic syndromes, and treatment of squamous cell?
smoking, central, Parathyroid hormone related peptide (hyoercalcemia), stage, chemo, rad, resection
27
patho, location, and treatment of adenocarcinoma?
asbestos (people who dont smoke get this), peripheral, stage, chemo, rad, resection
28
patho, location, 1 paraneoplastic syndromes, and treatment of carcinoid?
serotonin related, anywhere, serotonin syndrome (check 5HIAA in urine), stage, chemo, rad, resection
29
2 forms of pleural effusion?
transudate and exudate
30
4 causes of transudate?
``` CHF nephrotic syndrome gastrosis cirrhosis essentially fluid coming out of capillaries ```
31
3 causes of exudate?
malignancy, pneumonia, TB
32
What to start with when trying to diagnose effusion?
CXR to see that there is fluid
33
3 image modalities to see if the effusion is loculated? | If it is, how to manage loculated?
US, CT, lateral cxr (best because cheapest) | thoracostomy, if fails, thoracotomy
34
How do you treat effusion in CHF?
lasix, if that fails, thoracentesis
35
what is the lights criteria to determine if it is transudate or eudate?
LDH of fluid (greater than 2/3 upper limit of normal) LDH of fluid/LDH of serum - greater than .6 Total protein of fluid/Total protein of serum - greater than .5 any one is positive it is exudate. All need to be negative
36
virchows triad?

big time clinical sign of DVT? Diagnose? Treatment?
unilateral leg/limb swelling distal to clot US anticoagulate

4 clinical symptoms to remember about PE?
cough up blood, chest pain, right heart strain due to increased pulmonary htn, hypoxia.
39
what if the wells criteria for PE is less than 2, what do you do?
d dimer to confirm no PE
40
what is the wells criteria is over 4 in CT and over 6 in VQ, what do you do?
``` CT angiogram (spiral CT) with contrast VQ scan if they have bad kidneys ```
41
How do you treat PE?
heparin to warfarin bridge for 5 days or INR is between 2 and 3, whichever is longer
42
What is the only indication for IVC filter and PE?
they are bleeding and next PE would kill them
43
When to use TPA?
BIG FREAKING CLOT
44
What is the underlying issue with ARDS?
the diffusion barrier is thicker because of the fluid that has leaked out leading to edema. remember, oxygen is diffusion limited.

What does the patient look like with ARDS?
sick as crap, short of breath, hypoxic, probably ICU on ventilator.
46
How do we diagnose ARDS?
pulmonary edema on CXR and seeing them in respiratory failure basically
47
What will the PCWP and LV function be in cardiogenic pulmonary edema from CHF and Pulmonary edema in ARDS?
PCWP in CHF up and LV fxn down | PCWP in ARDS normal or down and LV up or normal

how to treat ARDS?
intubate keeping TV down and RR up to keep CO2 under control | PEEP
49
What is the underlying, big picture problem of DPLD?
restricted fibrotic lung that does not oxygenate
50
2 clinical symptoms of DPLD? | What will the PFT show?
hypoxic and dry cough | FEV1/FVC will go up
51
best image modality for DPLD? | best way to diagnose?
high res CT | biopsy
52
most common treatment for DPLD?
steroids
53
3 rheumatoid diseases causing pulmonary fibrosis?
lupus, RA, and Systemic sclerosis

black, female, bilateral hilar LA,
55
what will high res CT show for DPLD?
ground glass opacities
56
What is the thing that will help you make the diagnoses of sarcoidosis from others?
noncaseating granulomas.
57
3 extra pulmonary manifestations of sarcoidosis?
heart block, bells palsy, E nodosum
58
4 step process to diagnose DPLD?
xray, high res ct, PFT and biopsy
59
two patient populations getting asbestos? x ray finding for asbestos? biopsy finding for asbestos?
shipyard and construction workers pleural plaques barbell bodies
60
two patient populations getting sillicosis? | Look like on xray?
rock quarry and sand blastingfibrotic nodules in upper lobes, TB
61
what lung exposure is associated with RA?
coal miners lung
62
what is the main difference to remember about hypersensitivity pneumonitis?
this is antigen mediated. fever, cough, sob hours after exposure, but remove the antigen and symptoms go away. dont use steroids just take away antigen
63
treat sarcoidosis?
steroids
64
Tb and malignancy will look similar clincially and the exudate will differ if there is an effusion by what?
TB will have leukocytes with ADA positive
