What is the Thermal Infusion Set used for?
The Thermal Infusion Set (TIS, NAR 35-0004) is a specialized IV administration tubing set for the QUANTUM Blood & Fluid Warming System, designed for warming crystalloid and colloid IV solutions only. It is NOT cleared for blood or blood products — for those applications, use the Thermal Transfusion Set–Blood (TTS-B, 35-0005). The TIS warms room-temperature (68°F) IV fluids to 100.4°F (38°C ± 2°C) at flow rates up to 200 mL/min.
Why use the TIS instead of the TTS-B for IV fluids?
The Thermal Infusion Set is designed and cleared specifically for IV fluid warming. Organizations running QUANTUM systems primarily for IV fluid warming (e.g., hypothermia prevention with crystalloid resuscitation) can stock TIS sets for routine use and reserve TTS-B sets for blood transfusion events, which may allow for more economical consumable management. Both sets provide equivalent warming performance for IV solutions.
What is the priming volume of the Thermal Infusion Set?
The Thermal Infusion Set has a priming volume of approximately 16 mL and a total tubing length of 80 in. The 20 drops/mL drip chamber allows gravity drip rate calculation using standard IV administration formulas. These characteristics are similar to conventional IV tubing, making the TIS setup intuitive for any provider experienced with standard IV administration sets.
How much IV fluid can the QUANTUM warm with a single battery charge using the TIS?
Using the Thermal Infusion Set, a fully charged QUANTUM battery (35-0002) can warm approximately 1,700 mL of 68°F (20°C) room-temperature IV fluid to an output temperature of 100.4°F (38°C ± 2°C). Actual capacity varies with ambient temperature and input fluid temperature. Colder IV fluids or colder ambient temperatures reduce per-charge capacity.
Does the Thermal Infusion Set require any special setup steps?
The Thermal Infusion Set is designed to set up like a conventional IV tubing set. Spike the IV bag and prime the line using the standard technique. Then connect the controller cable (from the QUANTUM Controller) to the port on the TIS — this activates the heating element. The QUANTUM warms up in 24 seconds. Unlike most fluid warmers, no plug orientation is required for the controller cable connection. No additional standard IV set is needed.
Is the Thermal Infusion Set CoTCCC-recommended?
Fluid warming is consistent with CoTCCC hypothermia prevention guidelines for Prolonged Field Care. In-line warming during IV resuscitation in cold environments is a PFC best practice. Confirm current CoTCCC guidance with your medical director.
What training is required?
IV fluid resuscitation is a provider-scope skill at TCCC medic level (68W, 18D, Navy corpsman) and above. In-line warming set use is taught within PFC curriculum. Confirm scope of practice requirements with your unit medical officer.
Is the Thermal Infusion Set compatible with all IV fluid types?
The set is designed for crystalloid and colloid IV fluid warming. For blood product warming, use the NAR Thermal Transfusion Set — BLOOD. Confirm compatibility with your specific fluid type and IV line configuration before deployment.
Is there an NSN for government procurement?
Contact MED-TAC International or North American Rescue for current NSN and CAGE code for DLA procurement.
How does the Thermal Infusion Set work without power?
The Thermal Infusion Set uses a passive thermal exchange mechanism that warms IV fluids to near-body temperature during line transit without electrical power. This makes it suitable for austere and remote field environments. Refer to narescue.com for full technical specifications.
