The heart sits inside our chest and believe it or not, “weighing between 250-350 grams.” It may not sound like much but it is. “The heart contains 4 chambers that essentially make up 2 sides of 2 chamber (atrium and ventricle) circuits ; the left side chambers supply the systemic circulation, and the right side chambers supply the pulmonary circulation” (Medscape).

Irreversible shock “is the stage in which, regardless of the intervention, the patient outcome is death” (book421). Once a person has reached this stage, there is nothing that can be done. “The length of time that poor perfusion has existed begins to take a permanent toll on the body 's organs and tissues. The heart 's functioning continues to spiral downward, and the kidneys usually shut down completely” (EMS 1). TRANSITION
