How responsive is
your NIRS technology?

Find out with the flex challenge.

We ran four leading near-infrared spectroscopy (NIRS) technologies in a demonstration to see how quickly they respond to desaturation. Our 62-year-old patient wore a blood pressure cuff pumped to 200 mmHg to simulate desaturation. Watch the video below to see what happens.

Differences in response times

To ensure clinicians can achieve the best outcomes for their patients, care should be taken when selecting a regional oximeter. New data supports the conclusion that other NIRS devices do not respond the same as the INVOS™ regional oximetry system during critical physiological challenges, such as hypoxia or shock.1–3

Take the flex

When seconds matter, don’t wait until it’s critical to know how fast your NIRS technology responds to changes in oxygen desaturation. Take the flex challenge today and compare your NIRS technology to the INVOS™ 7100 regional oximetry system.

We’ve set a
clinical reference

INVOS™ technology, formerly known as Somanetics, has set a standard in regional oximetry. In fact, when it comes to clinical evidence, no other cerebral/somatic oximeter is backed by a comparable volume of published, peer-reviewed research.

The best
just got better.

The INVOS™ 7100 system provides the same proven clinical responsiveness as the INVOS™ 5100C system with an intuitive interface that’s easy to use. And the portable, lightweight tablet-style monitor is easy to move with the patient to any intrahospital location, so you can maintain continuous monitoring.

Sensors for
every patient

With INVOS™ 7100 sensors available in adult, pediatric, and neonatal sizes, you can be assured that your patients have a sensor that fits their unique size and anatomy.

See the difference in person. Request to have a Medtronic representative come to you with the INVOS™ 7100 system to help you do an in-person flex challenge.

The INVOS™ 7100 cerebral oximetry system should not be used as the sole basis for diagnosis or therapy and is intended only as an adjunct in patient assessment.
