Question

Consider a patient with a systemic infection, experiencing septic shock, in whom the resistance of the systemic circulation of the cardiovascular system decreases significantly. Assume that the driving pressure (the P of the system) stays the same. Why, under these circumstances, might you hear a cardiac murmur from blood flowing through one of the heart valves? (note: Murmurs are heart sounds related to vibrations of valve leaflets or vessel walls)

(note: Murmurs are heart sounds related to vibrations of valve leaflets or vessel O The flow of blood across the valve is reduced O The velocity of blood across the valve is reduced. O The velocity of blood across the valve is increased The flow across the valve transitions from turbulent to laminar because of the change in vascular resistance

Explanation / Answer

Under these circumstances,Cardiac murmur from blood flowing through one of the heart valves is,

d.The flow across the valve transitions from turblent to laminar because of the change in vascular resistance.
