Venous return curves showing the normal curve when the mean systemic filling pressure (Psf) is 7 mm Hg and the effect of altering the Psf to 3.5, 7, or 14 mm Hg.

The horizontal axis of Guyton diagram represents right atrial pressure or central venous pressure, and the vertical axis represents cardiac output or venous return. The red curve sloping upward to the right is the cardiac output curve, and the blue curve sloping downward to the right is the venous return curve. A steady state is formed at the ...
The jugular venous pressure (JVP, sometimes referred to as jugular venous pulse) is the indirectly observed pressure over the venous system via visualization of the internal jugular vein. It can be useful in the differentiation of different forms of heart and lung disease. Classically three upward deflections and two downward deflections have ...
The rest of the NBA spent this week feverishly trying to play catch-up with the league-leading Thunder; Chet’s return might mean that OKC’s about to shift into a new gear and leave everybody ...
The obturator sign, also called Cope's obturator test, is an indicator of irritation to the obturator internus muscle. [1] The technique for detecting the obturator sign, called the obturator test, is carried out on each leg in succession. The patient lies on her/his back with the hip and knee both flexed at ninety degrees.
