What is the QUANTUM Battery used for?
The QUANTUM Battery (35-0001) is the power source for the NAR Quantum Blood & Fluid Warming System — a compact portable blood and fluid warmer. The 44V battery powers the Quantum controller, which drives the warming element in the Thermal Transfusion Set (TTS-B disposable) to heat cold blood and IV fluids to 100.4°F (38°C) before administration, preventing transfusion-associated hypothermia.
How many units of blood can the QUANTUM Battery warm per charge?
On a single QUANTUM Battery charge, the Quantum warming system can warm two units of 39°F refrigerated whole blood at 100 mL/min to an output temperature of 100.4°F. For IV fluids at room temperature (68°F input), the capacity is 1,700 mL per charge. A spare QUANTUM Battery doubles this capacity, enabling warming of four blood units or 3,400 mL of IV fluid between charging opportunities.
Is the Quantum system still in production?
No. North American Rescue announced the discontinuation of the Quantum Blood & Fluid Warming System due to insurmountable supply chain manufacturing challenges with key components. While existing Quantum systems remain functional, future availability of batteries (35-0001), controllers, and TTS-B disposables will be limited. Providers requiring ongoing blood and fluid warming capability should evaluate the QinFlow Warrior EXTREME as the current-production alternative.
What is the expected battery life of the QUANTUM Battery?
The QUANTUM Battery is rated for up to 400 charging cycles before significant capacity degradation. For units that use the Quantum system regularly (multiple blood warmings per exercise or deployment), battery replacement at the 400-cycle mark ensures optimal warming performance. Given the discontinuation announcement, providers should also consider the long-term parts supply risk for replacement batteries.
What is the recommended replacement for the discontinued Quantum system?
NAR and MED-TAC International recommend the QinFlow Warrior EXTREME Blood & Fluid Warmer Set as the primary current-production alternative. The Warrior EXTREME provides superior delivery rates (up to 200 mL/min vs. 100 mL/min for Quantum), greater battery capacity per charge, dual AC/battery operation, MIL-STD-461G and IP56 certifications, and is validated for use with the NAR LifeFlow PLUS rapid infusion device — making it a comprehensive upgrade for units transitioning from the Quantum platform.
What is the QUANTUM Battery used for?
The QUANTUM Battery (35-0002) is the 44V lithium power source for the NAR QUANTUM Blood & Fluid Warming System. It drives the warming elements in the Thermal Transfusion Set (TTS-B) to heat cold blood and IV fluids to 100.4°F (38°C) for normothermic infusion.
How many blood units can one QUANTUM Battery warm per charge?
A fully charged QUANTUM Battery warms two units of 39°F refrigerated whole blood at 100 mL/min to 100.4°F. For 68°F IV fluids, capacity is approximately 1,700 mL per charge.
Is the QUANTUM system still in production?
North American Rescue has announced QUANTUM system discontinuation due to manufacturing supply chain constraints. Existing systems remain functional, but future availability of batteries, controllers, and TTS-B disposables will be limited. Providers planning for long-term blood warming capability should evaluate current-production alternatives.
What is the expected cycle life of the QUANTUM Battery?
The QUANTUM Battery is rated to up to 400 charge cycles under normal use conditions. Track cycle count and replace proactively as the battery approaches its rated service life.
Is the QUANTUM Battery compatible with other blood warmer systems?
No. The QUANTUM Battery is proprietary to the NAR QUANTUM Blood & Fluid Warming System only. It is not cross-compatible with other blood warming platforms.
