Masimo secures CE mark for RAS-45 sensor for rainbow Acoustic Monitoring of respiration rate

Masimo has secured CE mark for its RAS-45, a single-use adult and pediatric acoustic respiration sensor for rainbow Acoustic Monitoring (RAM) of respiration rate (RRa).

Masimo has secured the CE mark for its RAS-45, a single-use adult and pediatric acoustic respiration sensor for rainbow Acoustic Monitoring (RAM) of respiration rate (RRa).

Constant monitoring of respiration rate is essential for post-surgical patients receiving patient-controlled analgesia for pain management.

Anesthesia Patient Safety Foundation (APSF) recommends continuous monitoring of oxygenation and ventilation for patients on opioid-based medications for pain.

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.”

Making use of an adhesive sensor with an integrated acoustic transducer such as Masimo’s RAS-125c and now RAS-45, that is applied to the patient’s neck,  RAM noninvasively and continuously measures respiration rate.

The respiratory signal is separated and processed to indicate continuous acoustic respiration rate (RRa) by using acoustic signal processing that leverages Masimo’s Signal Extraction Technology (SET).

RRa has been indicated to be accurate, easy-to-use, and reliable, and enhances patient compliance.

Further, RRa may facilitate earlier detection of respiratory compromise and patient distress, thereby offering a breakthrough in patient safety for post-surgical patients and for procedures requiring conscious sedation.

RAS-45 is intended to facilitate placement on and improve attachment to the neck, but with a smaller adhesive profile than the RAS-125c.

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

Further, it is flexible and uses a transparent adhesive.

Just as the RAS-125c, it operates with Masimo MX technology boards to measure RRa and displays the acoustic respiration wave form.

RAS-45 maintains the same performance parameters, range, and accuracy specifications as RAS-125c. Both sensors are for patients who weigh over 10kg.
