Masimo Receives Sustainability Seal of Approval from Practice Greenhealth

Masimo Becomes First Pulse Oximetry Manufacturer to be Recognized with Coveted “Greenhealth Approved” Seal

Masimo (NASDAQ: MASI), a leading medical technology innovator, and Practice Greenhealth, a prominent organization dedicated to advancing sustainability solutions for healthcare providers, today announced that Masimo is now a recipient of the Greenhealth Approved seal. Masimo’s products – in particular its line of RD pulse oximetry sensors – are the first pulse oximetry products to receive the Greenhealth sustainability seal. The seal is only granted to products that meet specific sustainability criteria, making it a reliable indicator for health care providers seeking to identify environmentally preferable products without the time and expense needed to conduct their own independent verification.

Greenhealth Approved: Masimo RD Pulse Oximetry Sensors (Graphic: Business Wire)

Bilal Muhsin, Chief Operating Officer, Masimo, said, “Masimo is committed to both excellent patient care and environmental responsibility. The RD pulse oximetry sensor line was designed with the environment in mind, so we are pleased and proud to be the first to receive the Greenhealth Approved seal in this category.”

Masimo continually strives to make its products, packaging, and facilities more environmentally friendly and has implemented a variety of green initiatives, including designing products that promote sustainability by eliminating unnecessary material from being introduced into the product stream, expansion of its sensor recycling program, which is committed to achieving “zero waste to landfill,” and partnership with sustainability-focused organizations such as Practice Greenhealth.

From sensor design to disposal, Masimo uses materials that are less wasteful without compromising quality or performance. In addition to meeting the chemicals criteria of Health Care Without Harm, RD single-patient-use pulse oximetry sensors also:

• Reduce waste by 84% when compared to cable-based sensors¹
• Achieve zero waste to landfill through Masimo’s sensor recycling program
• Allow for “reprocessing at the bedside” with replacement tapes
• Offer best-in-class SpO₂ accuracy specifications of 1.5% A_RMS* and accurately measure on patients with varying skin pigmentation and low perfusion^2,3
• Maximize patient comfort with low-profile, lightweight components
• Use the same, standardized connector for multiple sensor technologies (e.g. SET^® and rainbow^®)

The review process for the Greenhealth Approved seal includes the submission of a complete ingredient list along with proof of certifications for the category’s criteria. “Greenhealth Approved removes obstacles that previously made purchasing sustainable products difficult,” said Paul Bogart, Executive Director of Practice Greenhealth. “Normally each health care provider conducts its own product review, often without extensive experience in chemistry and sustainability. We are helping streamline and centralize this approach, working closely with each supplier and completing a detailed product review using trusted criteria. Greenhealth Approved allows health care providers to quickly and easily identify and purchase sustainable products that decrease their impact on the environment.”

Providers interested in finding out which products carry the Greenhealth Approved seal can check the website and sign up for regular updates as products are approved for the seal. Practice Greenhealth is the leading sustainable health care organization, delivering environmental solutions to more than 1,700 hospitals and health systems in the United States and Canada.

Masimo will be exhibiting its Greenhealth-approved RD pulse oximetry sensors at CleanMed 2024, the premier health care sustainability conference, hosted by Practice Greenhealth and Health Care Without Harm, on May 21^st - 23^rd in Salt Lake City, Utah.
