Heart Kussmaul's breathing and sign

Do not confuse the two:

Kussmaul's breathing is seen in diabetic ketoacidosis (acetone breath).

While Kussmaul's sign is an elevated Jugular Venous Pressure seen during inspiration in constrictive pericarditis or improper filling of the heart. (It's not seen in cardiac temponade though).
Also seen in constrictive cardiomyopathy, severe right sided heart failure, and tricuspid valve stenosis all of these leads to the same pathophysiology of improper heart filling during inspiration.

Do not confuse Kussmaul's sign with
HepatoJugular Reflux?

Default why do they have those types of words

where there is one name for different things, even if one person discovered it or whatever why can't they just change the name to make it less confusing

Kaplan specifically mentioned Kussmaul's sign in Cardiac myxoma where the mitral valve can be obstructed by the tumor.
It goes with your definition by improper filling of the heart

Dis is wt i think....
In CP der is fibrosis of pericardium... So during rt atrial filling, atrial wal cannot dilate( decreased compliance)..so der is back flow of blood into jugular vein... Which is interpteted as raised JVP...
In CT, the pericardium is filled wit fluid.. No fibrosis.. Compliance is slightly decreased... Atrial filling is not severely hampered to see as a raised JVP...

Kussmaul's pulse (pulsus paradoxus) is seen in severe cardiac tamponade, constrictive pericarditis,obstructive sleep apnea,restrictive cardiomyopathy

pulsus paradoxus (korotkoff sound) - a decrease in systolic blood pressure of greater than 10 mm Hg with inspiration
