Pulmonary Conditions & Tobacco Cessation Flashcards

1
Q

What is pulmonary arterial htn?

A

-high BP in pulmonary artery (mPAP > 25)
-diagnosed with a right heart catheterization
–> imbalance of vasoconstrictor/vasodilators, imbalance of proliferation/apoptosis = enlarged right ventricle and right heart failure
Symptoms: fatigue, dyspnea, chest apin, syncope, edema, raynaud’s phenomenon

Q

drugs that can cause PAH?

A

-cocaine and methamphetamines
-fenfluramine
-SSRI use during pregnancy (can inc risk of persistent pulmonary htn of a newborn)
-weight loss drugs (phentermine, diethylpropion, phendimetrazine)

Q

Treatment of PAH

A

Non-drug: sodium restriction and immunizations
Drug:
-start: warfarin (INR 1.5-2.5) +/- diuretics +/- oxygen +/- Digoxin –> right heart cath and acute vasoactive testing =
+ : oral CCB (not verapamil)
- : begin a PAH approved drug
—> PDE-5 inhibitor
–> endothelin receptor antagonist
–> soluble guanylate cyclase stimulator
–> prostacyclin analogue

Q

Diagnosis and assessment of Asthma

A

via spirometry
-FEV1: how much air can be forcefully exhaled in 1 second
-FVC: the max volume of air that is exhaled after taking a deep breath
-FEV1/FVC: the percentage of total air capacity (vital capacity) that can be forcefully exhaled in 1 sec

Criteria: measure FEV1 –> give bronchodilator –> measure FEV1 –> inc FEV1 > 12% = reversibility/diagnosis
