What is the physiology of venous insufficiency?
Syndromes related to venous insufficiency are caused by valve incompetence. Venous insufficiency is a chronic (long term) condition
What drains venous blood from the brain and delivers it to the internal jugular veins?
dural venous sinuses
What is the function of venous valves?
Valves aid in venous return by preventing the back flow of blood.
Tip the bed head down for venous return?
No, lift legs for venous return. Make sure legs are above heart. You do this for shock or bleeding.
How does positive-pressure ventilation affect cardiac output?
It increases intrathoracic pressure which decreases venous return to the heart and causes a decrease in cardiac output.
How does positive pressure ventilation affect cardiac output?
It increases intrathoracic pressure which decreases venous return to the heart and causes a decrease in cardiac output.
How does the venous return mechanism work?
pressure gradient , gravity , skeletal muscle pump, thoracic pump and cardiac suction would be the mechanisms for venous return.
What increases stroke volume?
increase venous return
Why the jugular venous pressure falls during inspiration?
because the endothoracic pressure is decreased and the venous return to the heart is increased.
How can massage therapy help one's posture?
Improvement in posture through changing tension patterns that affect posture.
What is return blood?
Return blood, most likely, refers to the venous blood that is returned to the heart.
