What is Shock? Inadequate blood flow leading to inadequate oxygen delivery to body tissues May occur with blood loss as little as two pints Will result in death unless corrected

Role of Oxygen Oxygen catalyzes fuel production, thus providing energy to cells and tissues No oxygen=No energy No energy=No life

Cardiovascular System Heart is the “pump” Blood vessels are the “pipes” Cardiovascular system must maintain sufficient blood flow through capillary beds in tissues to meet cellular oxygen requirements Also removes carbon dioxide and other waste products for elimination from body

Cardiovascular System Blood Flow (Perfusion) Life Inadequate Blood Flow (Hypoperfusion) Shock

Types of Shock Cardiogenic shock from heart failure (pump failure) Septic shock from infection (pipes failure) Neurogenic shock from spinal cord injury (pipes failure) Hypovolemic shock from hemorrhage or other fluid loss (nothing left in pipes to pump)

Hypovolemic Shock Loss of volume in cardiovascular system Causes of hypovolemic shock Hemorrhage from external or internal injury (a.k.a. hemorrhagic shock) Total body water loss from dehydration Plasma loss from burns

Signs and Symptoms of Hemorrhagic Shock External or internal injury Anxious and restless Dizzy or lightheaded Decreasing level of consciousness Rapid, shallow respirations

Signs and Symptoms of Hemorrhagic Shock Pale, cool, clammy skin Weak, rapid pulse Usually >120 Decreased blood pressure Falling blood pressure is a late sign of shock

Treatment of Shock Remember the ABCs! Maintain the airway and breathing STOP THE BLEEDING! Lie patient on back and elevate legs Prevent loss of body heat by covering with blanket, poncho, etc. Initiate IV therapy Evacuate to surgical assets ASAP
