3 Pulmonary Flashcards
Asthma severity types: what are each daytime and noctural sxs?
Daytime sxs, noctural sxs:
- intermittent: <2/wk, <2/mo
- mild persistent: <1/day, >2 mo
- mod persistent: >1/day, >1/week
- severe persistent: >1/day, frequent
- refractory
Asthma severity types: what are their PFTs (FEV1)?
- intermittent: >80%
- mild persistent: >80%
- mod persistent: 60-80%
- severe persistent: <60%
- refractory
Asthma severity types: what are their txs?
All have SABA
- intermittent: -
- mild persistent: low dose ICS
- mod persistent: LABA + low dose ICS
- severe persistent: LABA + high dose ICS
- refractory: PO Steroids
LABA can be replaced with LTA
Asthma exacerbation in ED: What PEFR goes into which severity categories? (generalization)
PEFR>70% mild
50-70 mod
<50 severe
Asthma exacerbation: the thing that saves lives is ____
steroids
Paraneoplastic syndromes of lung cancers:
- squamous
- small cell
- carcinoid
Squamous: PTH-rp (hyperCa)
Small cell: ADH (SIADH), ACTH (Cushing’s), Lambert-Eaton,
Carcinoid: serotonoin syndrome
Carcinoid tumor: intestine vs lung, what similarities and differences?
-what lab test?
Same sxs: flushing, wheezing, diarrhea
intestine: liver mets, R sided heart valve dz
lung: serotoin starts in lung, so L sided heart valve fibrosis
5-HIAA urine
Which lung ca often has pain, why?
Adenocarcinoma, b/c peripheral irritation of pleura
Pleural effusion: how much fluid before visible on CXR?
about 250cc before blunting of costophrenic angle.
Light’s criteria
If any positive, then exudate.
(2/3, 0.6, 0.5)
- LDH <2/3 upper limit normal (200)
- LDH (effusion/serum <0.6)
- Total Protein (effusion/serum <0.5)
Pleural effusion causes:
Transudate (3 main ones)
Exudate(3 big ones, and more)
transudate: CHF, Cirrhosis (low protein), Nephrotic syndrome (low protein)
USU BILATERAL
exudate: Infection, CA, TB. Also: PE, Hemothorax, chylothorax
USU UNILATERAL
Pt with pleural effusion that is loculated. Do what and why?
Can’t do thoracentesis.
Do tube thoracostomy, to prevent empyema formation if parapneumonic effusion. If wait too long and empyema forms, must to thoracotomy.
Pleural effusion thoracentesis sample: how many tubes and what tests to order?
Tube 1: CBC with diff (polys for PNA, Lymphs for TB/CA, RBC for hemothorax/CA)
2: cytology (looking for CA)
3. glu, pH, total prot, LDH (for light’s)
4. Gram stain, Cx, acid fast
Other tests possible
Pleural effusion: what test for TB? Other than acid fast and lymphs
ADA (adenosine deaminase)
Pt with PE. Also has met CA and short life expectancy. How to anticoag?
what is the exception to that rule?
Don’t use warfarin or NOAC.
Use LMWH for rest of life.
If brain mets, do IVC filter b/c risk of ICH
PE pt. How to do Hep bridge to warfarin?
5 days Hep, or until INR 2-3, whichever is LONGER
