because the endothoracic pressure is decreased and the venous return to the heart is increased.

What differentiates cardiac tamponade from tension pneumothorax as the cause of his hypotension?
in tension pneumothorax, regardless of phase of breating, inspiration or expiration, the pressure in the venous return, hense filling pressure to the right ventricle remains unchanged in tamponade, right ventricular filling increases during the inspiration phase of the breathing cycle, as there is less pressure applied to the surface of the heart, hense the diastolic expansion of the right vetricle is less restricted since the negative intrathoracic pressure, required for inspiration allows this expansion, hence filling on the RV, hense, less blood pressure in the jugular vein, hense less distention of the jugular vein. so... if you see fluctuating jugular vein distention by breathing cycle in a way that it flattens during inspiration, you are dealing with cardiac tamponade. only if there is no concomitant parrallel process of hypovolemia to cause decrease in blood volume , hense little to no jugulat vein distention.
What two points are used to measure jugular venous pressure?
usually assessed by observing the right side of the patients neck.
What drains venous blood from the brain and delivers it to the internal jugular veins?
dural venous sinuses
What does the medical abbreviation JVD mean?
Jugular Venous Distention
How does venous pressure rise during 2nd heart sound?
The venous pressure increases during the second heart sound because of the increased negative pressure. 2nd heart sound heard when AV valves close,ventricular diastole
Can the jugular vein be fixed after it is cut?
If either the jugular vein or the carotid artery is completely severed, the venous tissue will retract and will be extremely difficult, if not impossible to repair.
Venous drainage of head and neck?
Facial,occipital,superficial temporal,retromandibular,posterior auricular,internal jugular,external jugular veins
Can jugular venous distension cause feeding problems?
What is feeding issues due towards special needs?
What are the signs and symptoms of cardiac tamponade?
There is a pericardial space present in the heart. This space consists of fluid called pericardial fluid. This fluid is responsible to decrease the friction during the contraction and expansion of ventricles. When the amount of this fluid increases, the intrapericardial pressure increases. This results to the condition when the atria and ventricles fail to relax normally. This condition is the condition of cardiac tamponade and the ecg you study to get a brief knowledge on the above condition is cardiac tamponade ecg.
What is central venous pressure?
Normal central venous pressure is in the range of 2-8 cmH2O.
What do we call the fluid that is enclosed within the venous sinuses?
The fluid that is in the dural venous sinuses is venous blood that originates from the brain or cranial cavity. They collect blood from veins on the surface of the brain. Blood from the sinuses empties into the internal jugular veins
What is th icd 9 code for status post placement of right internal jugular central venous catheter?
v58.4
