Guide: Selecting a Blood- and IV Fluid Warmer

Choosing the right blood- and IV fluid warmer is critical for patient safety. 

Here are 6 essential factors to consider when selecting a warmer for your organization.

1: Choose between a portable, stationary, or dual-use solution.

First, determine whether you need a portable, stationary, or dual-use blood warmer, based on where and how it will be used.

• Portable warmers: Best for pre-hospital care, the military, or departments where mobility is essential.

• Stationary warmers: Good for operating rooms, ICUs, or labs with fixed, predictable locations.

• Dual-use solutions: Some devices function both portably and at stationary power sources, allowing the warmer to accompany a patient from point of injury through different hospital units.

2: Ease-of-use

Modern healthcare settings are fast-paced and blood and IV fluid warmers are frequently used in emergency situations where ease of use can make a critical difference.

When selecting a device, prioritize features such as:

• Intuitive controls for quick operation
• Minimal setup steps to save valuable time
• Fewer parts for straightforward handling and maintenance

3: Set-Up Time

Ensure the blood warmer’s setup time aligns with your clinical needs.

• Quick setup: Critical for emergency transfusions to enable rapid intervention and prevent excessive blood loss.
• Slower setup: May be acceptable for routine or planned procedures where immediate transfusion isn’t required. However, in emergencies, a longer setup can delay care and put the patient at risk.

For emergency transfusions, an ideal setup time, including priming and warm-up, should be no more than 30–60 seconds.

4: Priming Volume

Blood products are valuable and sometimes scarce. Devices with large priming volumes can waste blood and other ressources unnecessarily.

Look for warmers with:

• Minimal priming volume to conserve resources and minimize blood wastage.

5: Cleaning and Maintenance

Maintenance is an important consideration in blood warmer ownership, as it can impact both safety and long-term costs.

When evaluating devices, consider:

• Ease of cleaning

• Frequency and cost of maintenance

• Availability of replaceable components

A device that is simple to maintain saves staff time, minimizes the risk of cross-contamination, and reduces long-term operational costs.

6: Learn From Other Users

Real-world feedback is invaluable. Speak with other healthcare organizations using the warmer you are considering:

• Ask about ease of use, reliability, and maintenance
• Get insights on clinical outcomes and patient safety
• Manufacturers can often connect you with reference users
