Interstitial fluid or tissue fluid is a solution that bathes and surrounds the tissue cells of multicellular animals.t is the main component of the extracellular fluid, which also includes plasma and transcellular fluid. The interstitial fluid is found in the interstices-the spaces between cells (also known as the tissue spaces).
Cardiogenic shock is a clinical condition of inadequate tissue (end-organ) perfusion due to the inability of the heart to pump an adequate amount of blood. The reduction in tissue perfusion results in decreased oxygen and nutrient delivery to the tissues and, if prolonged, potentially end-organ damage and multi-system failure.
The first step in diagnosing cardiogenic shock is to identify that a person is in shock. At that point, emergency treatment should begin. Once emergency treatment starts, doctors can look for the specific cause of the shock. If the reason for the shock is that the heart isn't pumping strongly enough, then the diagnosis is cardiogenic shock.
