Pericardiocentesis Flashcards
tamponade from trauma is best treated with
subxiphoid window prcedure, though a temporizing pericardiocentesis can aid while preparing for this or definitive surgical repair
what is pulsus paradoxus
SBP drops >10 mmHg during normal respirations
During an acute rapidly expanding pericardial effusion, stroke volume will increase with removal of even a small amount of fluid (as little as _____) from the pericardial sac
50 mL
the key symptoms of tamponade are
dyspnea and chest pain
the classic ecg finding for tamponade
ELECTRICAL ALTERNANS
-alternating high- and low-voltage QRS complexes as the heart swings toward and then away from the ECG leads on the chest wall with each contraction
the most characteristic sign on echocardiogram for tamponade
RIGHT-SIDED HEART COLLAPSE
- during diastole, the RV presses inward
- during systole, the RA presses inward
