What is true regarding blood transfusions and special administration devices?

The correct answer asserts that the pressure for an external pressure infusion cuff should not exceed 300 mmHg. This is important because exceeding the recommended pressure can lead to complications during blood transfusions. Managing the pressure properly ensures that the blood is infused at a safe and controlled rate, minimizing the risk of hemolysis and other transfusion-related reactions.

In practice, maintaining this pressure threshold allows healthcare providers to ensure that the transfusion proceeds smoothly without causing damage to the blood product or the patient’s veins. Proper pressure management is critical to ensure both efficacy and safety during the administration of blood products.

Although some devices may be suitable for certain types of transfusions, not all devices are appropriate for all types. Usage of pressure cuffs may be necessary in cases where standard infusion rates are inadequate or the patient's condition requires more controlled delivery. Therefore, understanding the limits of pressure and the necessity of certain devices is crucial in transfusion practices.
