The rising incidence of cancer and the complexity of treatment protocols are key drivers of the patient temperature management industry. Patients undergoing chemotherapy or radiation often experience disrupted thermoregulation due to immune suppression or treatment side effects. In some cases, temperature modulation is used therapeutically. Hyperthermia, or thermotherapy, involves heating body tissues up to 113°F to destroy cancer cells while minimizing damage to healthy tissue. In May 2025, according to the National Cancer Institute, the U.S. is projected to witness around 2.04 million new cancer diagnoses and over 618,000 deaths. Breast, prostate, and lung cancers are expected to remain the most prevalent. Despite the high burden, cancer death rates have steadily declined since the 1990s, with annual decreases of 1.7% in men and 1.3% in women reported between 2018 and 2022.

Temperature management is also critical in cardiovascular procedures, where maintaining normothermia helps reduce complications and improve recovery. Cardiac surgeries and catheter-based interventions often require controlled temperature environments to stabilize metabolism, reduce ischemic injury, and support hemodynamics. In October 2024, according to the CDC, heart disease remained the leading cause of death in the U.S., responsible for over 919000 deaths in 2023, roughly 1 in every 3. It affects people across all racial and ethnic groups, with coronary artery disease being the most common type. The growing prevalence of cardiovascular disease and increased use of minimally invasive procedures are driving demand for advanced temperature management systems in surgical and interventional settings.

Strategic partnerships and distribution agreements are expanding access to temperature management technologies. In January 2024, SourceMark announced a renewed partnership with Gentherm Medical, a leading manufacturer of temperature control systems. Through this agreement, SourceMark became the primary U.S. distributor for Gentherm’s specialized patient warming products. This collaboration reflects a broader industry trend toward improving product availability and clinical outcomes in surgical, critical care, and oncology applications.

Regulatory influence on the U.S. patient temperature management industry is moderate. Most devices in this category are subject to the FDA’s 510(k) pathway, which involves established standards for safety and performance. Although less stringent than approval for Class III devices, the regulatory process still requires comprehensive validation and can impact timelines and development costs, particularly for systems with digital health features.

The availability of substitutes in the U.S. patient temperature management industry is low. While conventional methods such as ice packs and warming blankets are still used in some clinical settings, they lack the precision and control offered by advanced systems. For critical applications, including post-cardiac arrest care and neurocritical procedures, modern temperature management devices remain the preferred standard of care.

Regional expansion in the U.S. patient temperature management industry is moderate. Health systems are increasingly extending temperature management protocols to community hospitals and outpatient surgical centers. Although adoption remains uneven in rural and underserved areas due to resource constraints, there is a clear trend toward broader geographic implementation driven by standardization efforts and increased demand for advanced critical care solutions.

Type Insights

Based on type, the patient warming systems segment led the market with the largest revenue share of 55.85% in 2024. This dominance is primarily driven by their widespread use in surgical procedures requiring general anesthesia. General anesthesia often results in a drop in core body temperature, increasing the risk of perioperative hypothermia. To mitigate this, patient warming systems are employed preoperatively to stabilize body temperature and improve surgical outcomes, making them a critical component of perioperative care. In July 2025, Medline launched the ComfortTemp Patient Warming System, featuring disposable blankets and gowns designed for effective temperature regulation in surgical settings. The 510(k) Class II device includes an innovative lock-in hose connection, rotating elbow connector, and flexible mounting options. It aims to reduce perioperative hypothermia while enhancing patient comfort.
