Week 3 Flashcards

1
Q

Next step in massive >600mL/24hr or >100/hr hemoptysis?

A

Secure airway (intubate), breathing, circulation, lay them so bleeding lung is in the dependent position (lateral position), then BRONCHOSCOPY, bcus it can localize bleeding, provide suctioning, and can be therapeutic (balloon tamponade, electrocautery).

Q

How to nitrates exert their effect?

A

Direct vascular smooth muscle relaxation causing venous dilation and increase in peripheral venous capacitance. Anti ischemic effect –> venodilation and decrease in cardiac preload, decrease in LVED and ES volume. This leads to a reduction in left ventricular systolic wall stress which reflects afterload (pressure *Radius/Thickness) and decrease in myocardial oxygen demand.

Q

Most common cause of MR in develped countries?

A

MVP which initially has mid systolic click and mid to late systolic murmur, but eventually has severe leaflet dysfunction and MR with holosystolic murmur. Though to be due to myxomatous degeneration of the mitral valve leaflets and chordae.

Q

Pathophys of high output HF?

A
