A patient involved in a motor vehicle accident has an abdominal trauma and is losing blood. The paramedics arrive, start and IV, and administer normal saline solution. Why do you think paramedics give normal saline solution and not blood in the ambulance?
2. Why might a physician be reluctant to order a blood transfusion unless absolutely necessary?
3. Even without a blood transfusion hematocrit can improve despite normal fluid volume. How does this happen and how long does it take?
4. Besides the HCT, what other component of blood is measured to give a better understanding of oxygen-carrying capacity? Explain your answer.
What is the relationship between blood pressure, heart rate, and respiratory rate when there is blood loss? Explain.
