Q

How does aspirin work?

A

Aspirin keeps platelets from sticking together and forming clots. It stops platelets from forming Thromoboxone which causes stickiness. Clots are what block arteries and result in ischemia and muscle death so therefore.

Q

How might Fentanyl help cardiac patients?

A

It causes peripheral vasodilation because in increases venous capicitance and decreases venous return, meaning it decreases both preload and after load which decreases myocardial oxygen demand.
