(47 cards)
Pulmonary circulation is _______ resistance, _______ pressure, and _______ compliance.
low; low; high
Causes of decreased DLCO (4)
Emphysema, Pulmonary Vascular Disease, Interstitial lung disease, Anemia
Causes of increased DLCO (4)
Polycythemia, Early CHF, asthma, alveolar hemorrhage
Causes of low V/Q and shunt (3)
congenital heart abnormalities, pulmonary disorders, pathologies resulting in transudate or exudate in the alveoli
Classic CXR findings in PE
Hampton’s Hump, Westermark’s Sign
Classic EKG findings in PE
S1 Q3 T3
Factors contributing to DLCO (3)
Surface Area, Membrane thickness, Hgb
In ___-capillary PH, the PCWP is
pre
Name the type: PH 1
Pulmonary Arterial Hypertension
Name the type: PH 2
PH due to left heart disease
Name the type: PH 3
PH due to lung disease/hypoxia
Name the type: PH 4
Thromboembolic Pulmonary Hypertension
Name the type: PH 5
PH with unclear or multifactorial mechanisms
Treatment for PE
Anticoagulation; consider thrombolytics, IVC filter, or thrombectomy
Treatment of PAH
Treat underlying cause, correct hypoxia, pulmonary vasodilators, consider antigcoagulation, lung transplantation
West Zone __: blood flow occurs during the entire cycle
3
West Zone __: flow through the vessels only occurs during systole
2
West Zone __: PA>Pa such that pulmonary vasculature is compressed and there is minimal blood flow
