CAMRT Radiography Practice Exam

What temperature should the warming sleeve of the pressure injector pump maintain for contrast?

1. About 37 degrees Celsius

2. About 25 degrees Celsius

3. About 40 degrees Celsius

4. About 30 degrees Celsius

The correct answer is: About 37 degrees Celsius

The correct choice indicates that the warming sleeve of the pressure injector pump should maintain a temperature of about 37 degrees Celsius. This temperature is significant because it closely approximates the normal human body temperature. Maintaining the contrast media at this temperature helps to minimize the risk of causing discomfort or adverse reactions in patients during imaging procedures. When contrast media is injected at temperatures significantly lower than body temperature, it can lead to feelings of coldness and discomfort for the patient. Additionally, warming the contrast medium can improve its viscosity and flow characteristics, ensuring that it travels through the vascular system smoothly, which is essential for optimal imaging results. Other temperature options may not adequately align with safety and comfort norms for patients. For instance, maintaining the contrast at temperatures much lower than body temperature could increase patient discomfort, while temperatures too high could potentially degrade the chemical integrity of the contrast agent. Therefore, keeping the warming sleeve at around 37 degrees Celsius strikes a balance that enhances the patient experience and ensures effective delivery of the contrast medium.
