NURS 4430 Chapter Notes - Chapter 14: Anaphylaxis, Antibody, Distributive Shock
Document Summary
Shock: a clinical syndrome that results from inadequate tissue perfusion creating an imbalance between the delivery of and requirement for oxygen and nutrients that support cellular function. Adequate blood flow requires an effective cardiac pump, adequate vasculature, and sufficient blood volume. Detect changes in oxygen saturation and carbon dioxide levels. Vasoconstriction, increased heart rate, increased contractility, no change in blood pressure. Mechanisms of blood pressure regulation can"t compensate; blood pressure begins to drop. The point that organ damage is so sever that the patient does not respond to treatment and cannot survive. Caused by: external fluid loss, traumatic blood loss, or by internal fluid shifts. When the hearts ability to contract and to pump blood is impaired and the supplu of oxygen is inadequate for the heart and tissues. Occurs when intravascular volume pools in peripheral blood vessels. Severe allergic reaction when patients who have already produced antibodies to a foreign substance develop a systemic antigen-antibody reaction.
