Pulmonary Flashcards
CF inheritance? mutation?
AR mut in CFTR gene
MC initial presentation of CF?
meconium ileus
Sx of CF
meconium ileus, FTT, Rectal Prolapse, Persistent cough, infertility(absent vas def), allergic bronchopulmonary aspergillosis, persistant cough, pancreatitis n shit like DM, hernia, amenorrhea, delayed puberty, RVH, portal HTN
Ivacaftor(VX-770)
first drug approved to tx CF = restores some function to the CF protein
3 things you can do for a CF patient that will IMPROVE SURVIVAL?
ibuprofen to reduce inflammation, Azithromycin to slow the rate of decline of FEV, abx during exacerbations
what is asthma?
REVERSIBLE airway obstruction
drugs that can worsen asthma?
ASA, NSAIDS, BB
+methacholine challenge test
> 20% decrease in FEV1 after methacholine = dx of asthm
FEV, FVC, FEV/FVC, TLC & RV changes in asthma
decreased FEV(major), decreased FVC, FEV/FVC, Increased TLC & RV
tx of asthma exacerbation?
Inhaled bronchodilators(albuterol), steroid bolus, inhaled ipratropium, oxygen and magnesium
so person has asthma. what do you start them on?
SABA
when do you up their medication from SABA
> 2d/w or >2n/m then add ICS!
when do you up their medication from SABA + ICS?
daily or >1n/w then add LABA
when do you up their medication from SABA + ICS + LABA?
frequent shit! just up the dosage of all
tx of acute COPD exacerbation
just like asthma! = albuterol,opratropium, steroids bolus, oxygen
what are the only 2 interventions that will decrease mortality and delay disease progression in COPD?
smoking cessation and long term home O2 use
when shoudl a pt with COPD be put on home O2?
PO2 <55% or O2 sat is <90%
what type of pt would you see A1AT def in?
<40, nonsmoker
sx of A1AT def
COPD on CXR, Low albumin, elevated prothombin due to liver cirrhosis, low A1AT
tx of A1AT def?
infusion with A1AT
Bronchiectasis
presentation/
anatomic defect resulting in profound dilation of bronchi = often due to multiple infections or CF.
sx: episodes of lung infections + HIGH(cups) volume of sputum, hemoptysis and fever, Tram tracking on CXR,
tx of bronchiectasis
chest physiotherapy = cupping and clapping, rotation abx to avoid resistance
Allergic bronchopulomonary aspergillosis(ABPA)
SX?
HSR to fungal antigens that colonize the bronchial tree
sx: cough up brownish mucous plugs with recurrent infections, peripheral eosinophilia, elevated IgE, cough, wheezing, hemoptysis and bronchiectasis
tx of Allergic bronchopulomonary aspergillosis(ABPA)
ORAL corticosteroids + Itraconazole
*cant use inhaled wont get past mucous plugs T.T
MCC of bronchiectasis?
CF
MCC of CAP
pneumococcus
MCC of HAP
gram - bacilli
when should you think pneumonia over bronchiectasis?
pneumo: tachycardia, tachypenia, hypotension
Empyema + criteria
infected pleural effusion that acts like abscess and only improves wiht drainage.
- LDH >60% of serum
- Protein >50% of serum
- pH <7.2, +gram stain or culture
which has a productive cough? lobar or intersitial pneumo?
