Masimo’s Rainbow Acoustic Monitoring (RAM) was associated with fewer alarm events during planned moderate sedation in a new clinical study1, according to the company.
In the two-part study, published in the journal Anesthesia & Analgesia, data were collected from adult patients undergoing gastroenterology or interventional radiology procedures under moderate sedation. The patients were monitored per standard protocols (electrocardiography, blood pressure, pulse oximetry, and capnography) along with the additional parameters RAM and SedLine. RAM and SedLine were not visible to the care teams in part one of the study (standard) but were visible to the care teams in part two of the study (advanced). Alarm events were defined as desaturation (SpO2 ?92%), acoustic respiration rate ?8 breaths per minute, and PSI ?50.
Data were analyzed from 90 patients (44 standard and 46 advanced). There were 55% fewer alarm events in advanced patients compared with standard patients (median 2.5 vs. 5.5, p=0.038). Fewer advanced patients had ?1 respiratory depression event (17 vs 26; p=0.035) or ?1 desaturation event (15 vs 25; p=0.02).
