Product-level market taxonomy classifies Patient Temperature Management Devices into surface systems, intravascular systems, and patient-temperature accessories. Surface systemsโwarming blankets, cooling pads, and capsโaccount for roughly 60% of installed units owing to non-invasive deployment and lower capital outlay. Within this subset, forced-air warming dominates orthopedic and ambulatory settings, while water-circulating pads prevail in neuro-ICUs for their superior heat-flux coefficients. Intravascular catheters, though costlier, deliver millimetric core-temperature control, proving critical during cardiopulmonary bypass and targeted temperature management post-arrest; their ASP exceeds $2,000 per circuit. Accessories, including esophageal or bladder probes and disposable sleeves, secure recurring revenue streams, often bundled in pay-per-procedure contracts. Collectively, the type-based segmentation underscores a market gravitating toward precision and disposability, with intravascular systems forecast to outpace surface alternatives at a 7.3% CAGR through 2028.
