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.
It's a sudden jolt. Now, most of the time when a defibrillator shock occurs in an appropriate session, whether it's an external shock through an AED or an internal shock through an implantable cardioverter defibrillator or ICD, if the patient is already unconscious, they won't ever feel or remember the shock.
