Similarly, you may ask, what are the 4 stages of shock?There are four stages of cardiogenic shock: initial, compensatory, progressive, and refractory. During the initial stage, there is diminished cardiac output without any clinical symptoms.Furthermore, what are the types of hypovolemic shock? Most often, hypovolemic shock is secondary to rapid blood loss (hemorrhagic shock). Two common causes of rapid internal blood loss are solid organ injury and rupture of an abdominal aortic aneurysm. Hypovolemic shock can result from significant fluid (other than blood) loss. Moreover, what happens to the body during hypovolemic shock? Hypovolemic shock happens when a sudden and significant loss of blood or body fluids drops your blood volume. Blood helps to hold your body temperature steady, forms blood clots, and moves oxygen and nutrients to all of your body’s cells. If your blood volume gets too low, your organs won’t be able to keep working.What is the management of hypovolemic shock?Three goals exist in the emergency department treatment of the patient with hypovolemic shock as follows: (1) maximize oxygen delivery – completed by ensuring adequacy of ventilation, increasing oxygen saturation of the blood, and restoring blood flow, (2) control further blood loss, and (3) fluid resuscitation.
