usually assessed by observing the right side of the patients neck.
Deoxygenated blood entering the right atrium is referred to as venous blood.
Equal pressure in and outIf the outward pressure inside your body were not equal to the pressure pressing in on you, you would be crushed faster than an empty aluminum beer can at a frat party. Try this experiment at home. It's pretty safe if you're not a maniac or an idiot.Find an old empty gallon can, a squarish one that paint thinner or turpentine comes in. Make sure its empty! Put an ounce or two of water in it. Put the can on the stove and heat it up until the water boils. Do this with the cap off!!! When the water boils, it will produce steam. When you see the steam coming out the top, screw the cap on. Don't burn yourself; use mitts. Let it cook for a few more seconds, not too long, tho. Then, using oven mitts, grab the can by the handle and quickly place it in the sink and run cold water over it. Watch what happens. Keep your hands away from it, tho. You don't want to get pinched.What happened? Well, when you quenched the can in the sink, the steam that had been filling the volume inside the can condensed, creating a vacuum -- an empty space -- inside the can. That created a low pressure in there. In other words, the pressure inside the can was much less then the pressure outside the can, creating a large pressure differential, causing the can to implode.A:well this is simple i may be young and not know alot but the fluids inside your body exert an equal amount of force all around you, thus actimg on the atmosphereic pressure and neutrilizing the effect (some of this may not be correct)A:Consider this, the atmospheric pressure of Jupiter is 90 times that of earth, that would crush a car absolutely flat. the reason why you do not collapse under atmospheric pressure is because our bodies have aclimatized over million of years ever since life started evolving here on earth. Our bodies have an upper and lower threshold of pressure which our bodies can withstand.A:Because your body exerts the same pressure outwards. That's why you need a pressurised suit to go into space - or to deep parts of the ocean. The pressurised suit stops your body exploding (in space) or collapsing (underwater)
If your ankles and body are swollen and retaining water, this could mean that your kidneys are not working properly. This also happens during pregnancy, and sometimes when a person gets too hot.
Technically, blood is always oxygenated to some degree. The capillaries are where the blood exchanges oxygen with the tissues so the blood entering the capillaries has more oxygen than the blood leaving the capillaries but under resting conditions venous blood is still 75% oxygenated.
People say that because the visible veins under your skin have a purple-ish blue color, due to the darkish red deoxygenated blood. Unfortunately, your blood is always red. This is the same misconception as saying Mountain Dew is green because of its green bottle, as an example.
because the endothoracic pressure is decreased and the venous return to the heart is increased.
Jugular venous distension is the visible bulging of the jugular veins in the neck. It can indicate increased pressure in the right side of the heart or in the superior vena cava. It is commonly seen in conditions like heart failure, cardiac tamponade, or constrictive pericarditis.
Jugular venous pressure is typically measured in millimeters of water (mm H2O) because it provides a more sensitive and precise way to assess changes in venous pressure. Using mm H2O allows for a greater resolution in detecting small changes in pressure compared to using other units such as centimeters of water or millimeters of mercury.
Jugular Venous Distention
The venous blood from the brain is drained by a network of veins called the cerebral venous sinuses. The largest of these sinuses is the superior sagittal sinus, which ultimately drains into the internal jugular veins.
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.

HVPG (Hepatic Venous Pressure Gradient) measurement involves measuring the pressure difference between the wedged hepatic venous pressure and the free hepatic venous pressure. During a TIPS procedure, the HVPG measurement is typically obtained by inserting a balloon catheter into the hepatic vein to occlude blood flow and measure the pressure. This is done before and after the TIPS creation to assess the change in portal pressure.
The blood pressure within the right atrium is called central venous pressure (CVP). It is a measure of the pressure in the large veins close to the heart and reflects the amount of blood returning to the heart.
What is feeding issues due towards special needs?
Normal central venous pressure is in the range of 2-8 cmH2O.
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
