IM-Respiratory Flashcards
(117 cards)
Empyemas are exudative effusions with a low glucose concentration due to ___ (2)
- A high metabolic activity of leukocytes
- bacteria within the pleural fluid
Pt with high dose beta-2-agonists can develop what kind of electrolyte imbalance and pt presentations are (6)
Hypokalemia
- Muscle weakness, arrhythmias & EKG abnormalities
- tremor, palpitations and headache
The 3 main (>90%) causes of a chronic cough in non-smokers are
- Postnasal drip
- GERD
- asthma
The main 3 systems that are affected by Theophylline toxicity are
- CNS (headache, insomnia, sz)
- GI (N/V)
- Cardiac (arrthytmia)
Panacinar emphysema is typical of what cause
alpha-1-antitrypsin deficiency
Supplemental oxygen in pt with COPD can worsen hypercapnia due to the combination of increased dead space perfusion causing (3)
- V/Q mismatch
- decreased affinity of oxyhemoglobin for C02
- Reduced alveolar ventilation
Acute exacerbation of COPD often reveals (4)
- Wheezes
- Tachypnea
- Prolonged expiration
- Accessory muscles
Bilateral wheezing can occur in acute PE due to _______ in response to hypoxia and infarction
cytokine-induced bronchoconstriction
PE causes V/Q mismatch resulting in an increase in ______
A-a oxygen gradient
Pneumonia causes hypoxemia due to (2)
- Right-to-left intrapulmonary shunting
- An extreme V/Q mismatch
Increasing concentration of inspired oxygen does/ does not correct hypoxemia caused by intrapulmonary shunting
Does NOT
Chronic nonproductive cough in patient with hearth failure is likely an
adverse effect of ACE inhibitor
How is Massive PE defined?
PE complicated by hypotension (syncope) and/or acute right heart strain (JVD & RBBB)
What are the pulmonary function tests seen for interstitial lung disease? (4)
increased FEV1/FVC ratio
decreased DLCO (diffused lung capacity of CO)
decreased TLC
Decreased RV
Pt with interstitial lung disease will have impaired gash exchange resulting in (2)
- reduced diffusion capacity of carbon monoxide
- increased alveolar-artery gradient
PE, atelectasis, pleural effusion, and pulmonary edema causes the
- V/Q to _
- A-a gradient _
- PaCO2 __
- RR__
- V/Q to Mismatch
- A-a gradient _ elevated
- PaCO2 __ decrease (respiratory alkalosis)
- RR__ Increased (to compensate)
GERD in pt with asthma can exacerbate asthma through micro aspiration of gastric contents leading to an increased in (2) & how to you treat
- Vagal tone
- Bronchial reactivity
-treat with PPI
Tx for mild non-allergic rhinitis
intranasal antihistamine or glucocorticoids
Tx for allergic rhinitis
- intranasal glucocorticoids
- antihistamines
-Triad of Fever, chest pain, hemoptysis
- Pulmonary nodules with halo sign
- positive culture
- positive cell wall biomarkers (galactomannan, beta-D-glucan)
Dx?
Invasive aspergillosis
Risk factor for Invasive aspergillosis
- Immunocompromise (neutropenia, glucocorticoids, HIV)
Tx of Invasive aspergillosis (2)
Voriconazole +/- Caspofungin
- > 3 months: Weight loss (>90%), cough, hemolysis, fatigue
- Cavitary lesion +/- fungus ball
- Positive Aspergillus IgG serology
Dx?
Chronic pulmonary aspergillosis
What is the risk factor for chronic pulmonary aspergillosis?
Lung disease/ damage (Cavity tuberculosis)
