Prolonged occlusion of the carotid arteries can result in serious brain damage
Carotidpulses
Correlate with central aortic pressure, thus reflecting cardiac function better than the peripheral pulses
When cardiac output is diminished, the peripheral pulses may be difficult or impossible to feel, but the carotid pulse should be felt easily
Bruit
A blowing or swishing sound created by turbulence of blood flow due to a narrowed arterial lumen or a condition that elevates cardiac output
Thrill
A vibrating sensation like the purring of a cat or water running through a hose, indicating turbulent blood flow due to arterial obstruction
Jugularveins
Drain blood from the head and neck directly into the superiorvena cava and right side of the heart
Externaljugularveins
Superficial and may be visible above the clavicle
Internal jugular veins
Lie deeper along the carotid artery and may transmit pulsations onto the skin of the neck
Normally, external neckveins are distended and visible when a person lies down; they are flat and not as visible when a person stands up, because gravity encourages venous drainage
