Cardiology — Flashcards

Flashcard 3591: How do PCWP and preload change during cardiogenic and obstructive shock?

Answer: Increased ($\uparrow$)

Extra: In **cardiogenic shock** and most forms of **obstructive shock** (e.g., cardiac tamponade, tension pneumothorax), PCWP is increased. This helps differentiate them from hypovolemic and distributive shocks, where PCWP is decreased. **Note:** PCWP is actually decreased in obstructive shock caused by a massive pulmonary embolism (since the obstruction is proximal to the left atrium).

Flashcard 3592: Appropriate absolute polycythemia is characterized by _____ RBC mass

Answer: increased

Flashcard 3593: Hypertrophic cardiomyopathy may impair _____ valve closure, thus causing regurgitation
