The RAS-45 sensor has been deigned to facilitate placement on and improve attachment to the neck, with a smaller adhesive profile than the RAS-125c.

Similar to the RAS-125c, the new respiration sensor operates with Masimo MX technology boards to measure RRa and show the acoustic respiration wave form.

RAS-45 includes same performance parameters, range and accuracy specifications as RAS-125c. Both are designed to be used for patients who weigh more than 10kg.

RAM noninvasively and continuously measures respiration rate using an advanced adhesive sensor with an integrated acoustic transducers such as Masimo's RAS-125c and RAS-45, which will be applied to the patient's neck.

Through using acoustic signal processing that leverages Masimo's Signal Extraction Technology (SET), the respiratory signal is separated and processed to display continuous acoustic respiration rate.

Masimo founder and CEO Joe Kiani said: “RAM harnesses the power of our breakthrough signal processing technology, using Masimo SET and rainbow technologies, and applies those achievements to a respiratory measurement derived from the sound of breathing.

“Studies have found that RAM RRa is more sensitive to detecting respiratory pause5 and yet easier for clinicians and patients to use.”

Earlier this month, the firm received CE mark approval for its pediatric O3 regional oximetry device, which enables clinicians to monitor cerebral oxygenation.

The approval has been granted for the pediatric indication for O3 regional oximetry with the O3 pediatric sensor.
