hypovolemic shock ppt

Crystalloids and blood were used extensively during World War II for the treatment of patients in unstable conditions. A healthy adult can withstand the loss of half a litre from a circulation of about five litres without ill effect; Most often, hypovolemic shock is secondary to rapid blood loss (hemorrhagic shock). This results in decreased venous return of blood to the heart and subsequent decreased ventricular filling. • The diminished preload decreases the CO and the SVR increases in an effort to compensate for the diminished CO and maintain perfusion to the vital organs. Trauma may result in a hemoperitoneum or hemothorax. Hypovolemic shock is caused by a decrease in the amount of circulating volume (absolute hypovolemia). Hypovolemic Hypovolemic shock affects both children and adults. This simulation case has been successful in helping students to recognize hypovolemic shock and associated abnormalities through history, clinical signs and symptoms, and interpretation of lab values. Hypovolemic shock refers to a medical or surgical condition in which rapid fluid loss results in multiple organ failure due to inadequate circulating volume and subsequent inadequate perfusion. Shock Prepared by :Doaa Al-ebraheem. diarrhea, vomiting, burns, third spacing, iatrogenic Hemorrhagic Shock . Shock The client has a central catheter and his mean arterial pressure (MAP) is 100 mmHg. Hypovolemic shock can result from significant fluid (other than blood) loss. Hypovolemic shock from uncontrolled hemorrhage is the quintessential form of shock among trauma patients. His central venous pressure is 0 mmHg and his cardiac output is 8.0 L/min. Hemorrhagic shock can also result from significant acute internal blood loss into the thoracic and abdominal cavities.
