Page 275: Cardiac Tamponade and Pulsus Paradoxus

What is Cardiac Tamponade? Cardiac Tamponade is a condition where the heart is compressed by fluid that collects around the heart, and this can happen by blood or even effusion. And because the fluid is in the pericardium, it will cause the compression of the heart, and this leads to decreased cardiac output, which happens due to the compression on the heart not allowing the heart to pump out sufficient blood.

What happens to diastolic pressure in all four champers during cardiac tamponade? There’s an equalization of diastolic pressure in all four champers in cardiac tamponade.

What are some of the findings observed in cardiac tamponade? Some of the findings include: Hypotention, increase in the venous pressure that leads to jugular venous distention, there’s also a distant heart sound that can be heard, increase in the heart rate and pulsus paradoxus.

What is “Pulsus Paradoxus” ? Pulsus Paradoxus is a decrease in the amplitude of Systolic pressure by greater than or equal to 10 mmhg during inspiration.

What are some of the conditions in which you will see pulsus paradoxus? some of the conditions in which you will see pulsus paradoxus include severe cardiac tamponade, asthma, Obstructive sleep apnea, pericarditis and croup.
