Companies are developing innovative technologies to help healthcare staff reduce transmission risks while increasing clinician and patient safety. For instance, in August 2025, Masimo received FDA 510(k) clearance of expanded indications for the delta hemoglobin parameters provided with O3 Regional Oximetry.

The rising prevalence of cardiovascular disorders is expected to drive market growth over the forecast period. For instance, according to the American Heart Association's 2025 Heart Disease and Stroke Statistics Update, cardiovascular disease remains the leading cause of death in the United States, with more than 941,000 deaths reported in 2022. Nearly 47% of U.S. Adults have high blood pressure, a major risk factor for cardiovascular disorders. Thus, the association of this technique with technological advances seems to enable rapid detection of cardiopathies, enhance medical treatment through remote control and patient surveillance in healthcare settings, and reduce the number of deaths caused by CVDs. PPG is a non-invasive, inexpensive technique compared to ECG sensors, and it can be easily incorporated at several sites, such as the fingers, toes, ear, wrist, chest, and head, to measure the signal.

The non-invasive PPG technique for measuring SpO2 and HR is widely used in personal handheld devices and clinical pulse oximetry due to its simplicity and ability to perform continuous readings. It is considered a compact, low-cost device with a basic application that is also non-invasive and applicable in a variety of settings. In addition, the development of signal processing algorithms enhances robustness, thereby advancing this technology. Owing to several advantages of PPG, demand for these biosensors will increase in the coming years, driving market growth.
