61
At which point should you perform a hepatojugular reflux test?
Should be at least a 3cm distance from the upper margin of the baseline JVP to the angle of the mandible
62
How do you perform the hepatojugular reflux test?
- Position the patient at 45 degrees - Apply direct pressure to the liver - Closely observe the IJV for a rise - If healthy: rise shouldn't last longer than 1-2 cardiac cycle - If raise is sustained and equal to or greater than 4cm = positive result
63
What may a positive hepatojugular reflux test indicate?
That the right ventricle is unable to accommodate an increased venous return
64
