Beck’s Triad is a set of three cardiovascular signs that indicate cardiac tamponade. These three signs got their name from the American cardiothoracic surgeon, Dr. Claude Beck, in 1935. In order to fully make sense of Beck’s triad and what it means, it's essential to understand cardiac tamponade.

Cardiac tamponade is an acute condition in which blood surrounds the heart, putting so much pressure on it, to the point where it is unable to effectively pump blood. You can think of it essentially as something squeezing the heart until it stops.

Surrounding the heart, there is a pericardial sac that is made up of two layers. Together, these two layers...

All living cells in the human body require oxygen in order to efficiently convert glucose into energy. In order for cells to receive oxygen, there needs to be adequate blood flow throughout the body so that oxygen-rich blood can deliver oxygen to the tissues and cellular respiration can occur. When there is impedance in the bodies’ ability to perfuse blood to the tissues, shock may occur. Shock occurs when there is a circulatory failure throughout the entire body, which results in cellular damage and can lead to multiple organ failures if not treated immediately.

Blood pressure is a major determinate in the perfusion of tissues because there needs to...
