Pulmonary edema/ICU

Question 1

stages of pulmonary edema

Answer 1

vascular redistribution, interstitial edema, alveolar edema

Question 2

assymetric pulmonary edema

Answer 2

RUL pulmonary edema caused by acute mitral regurgitation secondary to MI and papillary muscle rupture

Question 3

reexpansion pulmonary edema

Answer 3

aggressive thoracentesis and rapid reexpansion of lung collapsed for 3+ days`

Question 4

interstitial edema

Answer 4

increased interstitial markings, indistinct pulmonary vasculature, peribronchial cuffing, Kerley A/B lines

Question 5

vascular pedicle

Answer 5

transverse width of upper mediastinum (SVC and Right mainstem bronchus and lateral border of takeoff of subclavian from aorta)

<58 mm

Question 6

widening of vascular pedicle

Answer 6

increased pulmonary capillary wedge pressure/fluid overload

Question 7

ETT

Answer 7

4-6 cm above carina with neck in neutral alignment

Question 8

central venous catheters

Answer 8

lower SVC or cavoatrial junction

dialysis catheter: right atrium

azygos malpositioning can increase risk of venous perforation, catheter associated thrombosis

Question 9

Swan-Ganz pulmonary artery catheter

Answer 9

IJ > SVC > RA > tricuspid >RV > pulmonic valve > pulmonary artery

tip should be in main/right/left pulmonary artery

distal to interlobular pulmonary artery &raquo_space;pulmonary artery rupture or pseudoaneurysm; intracardiac catheter knot, arrhythmia
