Step 1
A tourniquet is a device used to apply pressure to a limb or extremity in order to limit – but not stop – the flow of blood. It is needed in venipuncture procedures to make the veins more visible and palpable, making it easier to locate the vein and insert the Show more…

1. 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.

How do blood transfusions work? - Bill Schutt. Answer the following questions in complete sentences. 1. Dr. Denis transfused sheep blood into his patient Antoine Mauroy. This seems weird now, but why might this have seemed like a logical thing to do in 1667? 2. Why was Karl Landsteiner's discovery of blood types so important? 3. Why might you argue that the discovery of heparin was as important a lifesaver as the discovery of blood types? 4. What is the mechanism heparin uses to preserve blood? 5. Which chemical was used before heparin? How did it work?
Place the following steps of the hematocrit procedure in order. Cleanse the end of the test subject's finger with an alcohol swab Prick the finger with a lancet and wipe away the first drop of blood with the alcohol swab Draw blood into a heparinized capillary tube Plug the blood end of the tube with sealing clay Place the sealed tube into a microhematocrit centrifuge and spin for 3-5 minutes
