Why is mixed venous blood sample monitored?
Because that is where all of the venous blood runs through just before it enters the lungs and becomes re-oxygenated. So it is the most mixed up venous blood in the body.
What is a venous duct?
The venous duct connects the umbilical arteries to the liver.
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 central venous pressure?
Normal central venous pressure is in the range of 2-8 cmH2O.
Does isosrbide cause venous pooling?
yes
CArdiac output may drop when one goes from lying to standing position because of?
Venous pooling results in a decrease in cardiac output when a person goes from a lying to standing position. Venous pooling occurs when there is a buildup of blood in the veins of the legs that results due to gravitational pull when changing positions.
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.
What happens to your liver during shock?
Hypovolemic shock markedly decreases total liver blood flow by a reduction in portal venous blood flow.
Why is mixed venous blood sample monitored?

What are the valves in the veins called?
To prevent back flow of blood as the blood pressure in veins is greatly decreased compared to artieries
Does the muscular system effect the body systems?
it does... in the lower legs, the muscle contractions help the venous valves to keep venous flow moving upwards, helping the blood move from the feet to the heart, preventing pooling of venous bloods and conditions like varicose veins. intercostal muscles help in breathing especially at times of high exertion like sprinting. the heart is a muscle itself: made of cardiac muscle. these are only some examples.
What causes Neurogenic shock?
Neurogenic shock is normally caused by injury that occurs to the nervous system. Other conditions can also cause this type of shock including hypertension and reduced blood flow.
Can hypotension caused by shock be treated by IV fluids?
Yes, that would be a normal response to shock to try and save the internal organs by pooling the blood to the abdomen and thoracic cavity and lowering it at the extremities. Giving IV fluids would increase of fluids in the body and that would raise blood pressure and help avoid complications from shock.
What causes venous ulcer?
Venous ulcer are caused by venous insufficiency (improper functioning of venous valves).
What is pooling substation?
The Substation which comes power from the power plant know as pooling substation.
Does venous in venous Doppler get capitalized?
