Unmet Clinical Need

Inadvertent Perioperative Hypothermia is the sudden drop of core temperature below 36C pre-, intra-, or post-operatively. A lack of preoperative warming combined with the vasodilatory effects of anesthesia leads to a precipitous reduction in core temperature that is often too difficult to remedy during surgery.


Patients are exposed to cold environments, surfaces, and liquids throughout surgical care.

Loss of peripheral vascular tone due to anesthesia results in redistributive hypothermia – cold peripheral blood recirculating at rates of -2°C per hour.1


Despite existing interventions, there remains a 38-56% incidence of inadvertent perioperative hypothermia (IPH).2,3

Approximately 50% of patients are hypothermic prior to start of surgery and 33% at end.4


IPH clinically linked to higher odds of SSI (4x), cardiac events (2.2x), mechanical ventilation (1.58x), and bleeding (1.2x), all drivers of preventable costs.5,6


Market Opportunity

Currently, no warming solution helps maintain normothermia in a timely manner without impeding surgical site access and increasing the risk of surgical site contamination.

Over 100M patients annually undergo invasive or therapeutic surgical procedures at risk for developing inadvertent hypothermia. Patient warming and dynamic compression represent a $4.6 billion worldwide market with attractive growth rates and room for margin expansion.7,8 In the U.S. alone, over 58M procedures are at moderate to high risk for developing complications due to DVT and IPH.9

Leading healthcare regulators and organizations like CMS, NHS, NICE, and WHO remain unequivocally focused on reducing these complications.


Flotherm Thermal Compression Device (TCD)

Flotherm TCD is a medical device that combines the power of dynamic compression with lower-limb warming to deliver greater control over perioperative safety. The TCD is the only non-invasive and non-surface area dependent solution to manage patient risk for IPH and DVT, driving perioperative compliance without changing existing surgical workflows.

Patient Safety and Usability

Engineered to maintain normothermia while delivering venous thromboembolism (VTE) prophylaxis in a single, patient-friendly solution

Clinical Workflow Integration

Novel design intended to obviate the risk of unintended surgical site contamination while preserving clinical access.

Clinical Evidence

Early clinical validation demonstrates superior management of normothermia compared to forced air warming.
