HOTLINE® Blood and Fluid Warming Systems

The HOTLINE® blood and fluid warmer offers a safe, reliable, and proven technology to consistently warm and deliver blood and fluids to patients undergoing surgical procedures.

Fluid warming is a method of raising the temperature of fluids administered to a patient to maintain normal body temperature and prevent hypothermia.

Consistent Performance

The HOTLINE® blood and fluid warmer provides the most consistent normothermic blood and fluid delivery performance across a range of fluid warmers. This consistency is achieved through the unique system design which is comprised of a warmer with a pump to circulate warmth-transferring fluid and a disposable fluid warming set with triple lumen construction. The triple lumen tubing allows blood or fluid to be warmed as it travels through the sterile center lumen while heated circulating fluid flows through the outer lumens, enveloping the center lumen in warmth.

Thermal Heat Mapping

Unlike the HOTLINE® blood and fluid warmer, conventional fluid warming systems suffer from patient line cool down as the intravenous fluid travels from the warmer to the patient. This is because the infused blood or fluid is only warmed within the conventional warmer heater, allowing it to cool as it travels through the I.V. line before reaching the patient.

Unmatched Safety

With a HOTLINE® blood & fluid warmer from Smiths Medical, be confident in knowing that your patients will be warm and protected.

Safety standards for medical equipment are rigorous and essential for the protection of both clinicians and patients. The HOTLINE® blood and fluid warmer has undergone extensive testing to meet clinical expectations for performance and ensure its status as a safe tool for surgical environments.

Common surgical environments where the HOTLINE® blood and fluid warmer is used include:

  • Common surgical environments include Orthopedic Orthopedic
  • Common surgical environments include Abdominal Abdominal
  • Common surgical environments include OBGYN OBGYN
  • Common surgical environments include Cardiac Cardiac

Proven Reliability

For the past two decades, Smiths Medical Level 1® HOTLINE® blood and fluid warmer has played an integral part in the prevention of perioperative hypothermia in over 30 million surgeries.

With its unique triple lumen HOTLINE® fluid warming set, the HOTLINE® blood and fluid warmer is the only blood and fluid warming system that eliminates patient line cool-down and delivers consistently warmed fluids to the patient at routine, gravity flow rates.

The Importance of Maintaining Normothermia

View Hotline Animation

Keeping your patients at a normal body temperature is crucial to the prevention of complications resulting from unintended perioperative hypothermia, which occurs when the body’s core temperature falls below 36°C. Unintended perioperative hypothermia has been called a frequent, preventable complication of surgery. Among the 51 million inpatient and 34.7 million ambulatory surgeries occurring annually in the United States, it is estimated that 50-90% suffer from accidental hypothermia. (1-4)


Unintended perioperative hypothermia can be caused by a number of factors, including:

  • Administration of anesthesia
  • Administration of cold intravenous blood or fluids
  • Exposed surgical cavities
  • Cold operating theater temperatures

Research has shown that even a slight drop in patient temperature can have significant effects on patient outcomes. The negative effects of hypothermia include(9):

  • Surgical site infections
  • Myocardial ischemia
  • Prolongation of drug effects
  • Bleeding diatheses
  • Increased morbidity, mortality, and expense

Based on the negative impact of even mild drops in body temperature, a trend is emerging globally to adopt national quality initiatives related to improving patient care through temperature management.

Tubing Patient Warmer

Explore HOTLINE®

The performance of the HOTLINE® blood and fluid warmer is driven by its unique system design, comprised of a warmer with a pump to circulate warmth-transferring fluid and a disposable fluid warming set with triple lumen construction.

The triple lumen tubing allows blood or fluid to travel through the sterile center lumen of the HOTLINE® fluid warming set to the patient as heated circulating fluid flows through the two outer lumens, enveloping the center lumen in warmth. Because the outer and central lumens are entirely separate, the recirculating solution never comes in contact with the infused blood or fluid, and therefore presents no risk of cross-contamination and is an essential safety feature to the HOTLINE® blood and fluid warmer.
The HOTLINE® fluid warmer heats the circulating fluid to a temperature of 42°C to ensure blood or fluid is delivered to the patient at a temperature able to maintain normothermia.
Unlike the HOTLINE® blood and fluid warmer, conventional fluid warming systems suffer from patient line cool down as the infused blood or fluid travels from the warmer to the patient. This is because the infusate is only warmed within the conventional warmer heater, allowing it to cool as it travels through the I.V. line before reaching the patient.
