$465.90 million is the projected size of the global cerebral oximetry monitoring market by 2034, up from $228.13 million in 2025 and $244.61 million in 2026, implying an 8.4% CAGR.
Cardiac, vascular and neurocritical-care procedures are driving adoption because clinicians use the non-invasive monitors to track brain oxygen saturation during high-risk surgery, anesthesia, neonatal care and ICU treatment.
Sensors and probes led the market in 2025 because many are single-patient-use consumables, while cardiac surgery was the largest application and is expected to account for 50.1% of the market in 2026.
North America remained the largest region, reaching $112.19 million in 2025, with the U.S. projected at $116.17 million in 2026, or about 47.5% of global sales.
BD, Medtronic and Masimo held the biggest 2025 shares, but recurring consumable costs, uneven clinical thresholds and NIRS measurement variability still threaten wider adoption.
