New Study Evaluates the Ability of Masimo SedLine® Brain Function Monitoring to Predict Neurological Outcomes and Long-term Survival in Post-Cardiac Arrest ICU Patients
Masimo (NASDAQ: MASI) announced today the findings of a study published in the Journal of Critical Care in which Dr. Tae Youn Kim and colleagues at the Dongguk University College of Medicine and Yonsei University College of Medicine in Korea evaluated the ability of two parameters provided by Masimo SedLine® brain function monitoring to predict neurological outcomes and long-term survival in post-cardiac arrest ICU patients.1 The researchers found that the combination of the two parameters, Patient State Index (PSi) and Suppression Ratio (SR) had “high predictability” for mortality 180 days after cardiac arrest.

Noting that “accurate prognostication” in post-cardiac arrest patients is important to determine treatment plans and “whether to continue or withdraw intensive care,” and that a “multi-modal” approach is recommended because “no single prognostic factor has been shown to have higher prognostic accuracy than those of other factors,” the researchers sought to evaluate the prognostic accuracy of the two Masimo SedLine parameters as predictors of neurological outcomes, both alone and in combination. The researchers chose PSi because, as they note, raw EEG data can be “difficult to use” and PSi, which is derived from EEG, is widely used in anesthesiology for determining the degree of procedural sedation, “significantly co-varies with changes in the state” under general anesthesia, and “can significantly predict” the level of arousal in varying stages of anesthetic delivery. The researchers chose SR because it helps to estimate the percentage of EEG suppression and is therefore considered a good predictor of poor neurologic outcomes.2
They enrolled 103 adult patients between January 2017 and August 2020 who experienced a non-traumatic out-of-hospital cardiac arrest, had been successfully resuscitated after CPR, and received targeted temperature management during their ICU stay. PSi and SR were continuously monitored using Masimo SedLine from immediately after ICU admission until 24 hours after return of spontaneous circulation (ROSC), recorded at one hour intervals. Neurological outcomes were categorized using the Pittsburgh Brain Stem Score (PBSS) and Cerebral Performance Category (CPC). Data on survival at 180 days was obtained via telephonic interviews.
The researchers found that using either PSi or SR alone had “good predictability” for poor neurological outcome, and that the combination of low PSi and SR had “high predictability” for mortality 180 days after cardiac arrest. They used receiver operating characteristic (ROC) curves to determine that “a mean PSI ≤ 14.53 and mean SR > 36.6 showed high diagnostic accuracy” as single prognostic factors for patients in their study. Furthermore, “Multimodal prediction using the mean PSi and mean SR showed the highest area-under-the-curve value of 0.965 (95% confidence interval 0.909–0.991).” In the study cohort, patients with mean PSi ≤ 14.53 and mean SR > 36.6 had “relatively higher long-term mortality rates” (69% died in the group) than those of patients with values > 14.53 and ≤ 36.6 (11% died in the group).
The researchers concluded that “PSi and SR are good predictors for early neuro-prognostication in post-cardiac arrest patients.” They also noted, “The combination of PSI and SR showed better predictability of poor neurologic outcome than did each individual parameter.”

Masimo (NASDAQ: MASI) is a global medical technology company that develops and produces a wide array of industry-leading monitoring technologies, including innovative measurements, sensors, patient monitors, and automation and connectivity solutions. Our mission is to improve patient outcomes, reduce the cost of care, and take noninvasive monitoring to new sites and applications. Masimo SET® Measure-through Motion and Low Perfusion™ pulse oximetry, introduced in 1995, has been shown in over 100 independent and objective studies to outperform other pulse oximetry technologies.3 Masimo SET® has also been shown to help clinicians reduce severe retinopathy of prematurity in neonates,4 improve CCHD screening in newborns,5 and, when used for continuous monitoring with Masimo Patient SafetyNet™ in post-surgical wards, reduce rapid response team activations, ICU transfers, and costs.6-9 Masimo SET® is estimated to be used on more than 200 million patients in leading hospitals and other healthcare settings around the world,10 and is the primary pulse oximetry at 9 of the top 10 hospitals according to the 2020-21 U.S. News and World Report Best Hospitals Honor Roll.11 Masimo continues to refine SET® and in 2018, announced that SpO2 accuracy on RD SET® sensors during conditions of motion has been significantly improved, providing clinicians with even greater confidence that the SpO2 values they rely on accurately reflect a patient’s physiological status. In 2005, Masimo introduced rainbow® Pulse CO-Oximetry technology, allowing noninvasive and continuous monitoring of blood constituents that previously could only be measured invasively, including total hemoglobin (SpHb®), oxygen content (SpOC™), carboxyhemoglobin (SpCO®), methemoglobin (SpMet®), Pleth Variability Index (PVi®), RPVi™ (rainbow® PVi), and Oxygen Reserve Index (ORi™). In 2013, Masimo introduced the Root® Patient Monitoring and Connectivity Platform, built from the ground up to be as flexible and expandable as possible to facilitate the addition of other Masimo and third-party monitoring technologies; key Masimo additions include Next Generation SedLine® Brain Function Monitoring, O3® Regional Oximetry, and ISA™ Capnography with NomoLine® sampling lines. Masimo’s family of continuous and spot-check monitoring Pulse CO-Oximeters® includes devices designed for use in a variety of clinical and non-clinical scenarios, including tetherless, wearable technology, such as Radius-7® and Radius PPG™, portable devices like Rad-67®, fingertip pulse oximeters like MightySat® Rx, and devices available for use both in the hospital and at home, such as Rad-97®. Masimo hospital automation and connectivity solutions are centered around the Masimo Hospital Automation™ platform, and include Iris® Gateway, iSirona™, Patient SafetyNet, Replica™, Halo ION™, UniView®, UniView :60™, and Masimo SafetyNet™.

New Harris Poll: Cybersecurity Fears May Stall COVID-19 Digital Vaccine Card Adoption in the United Kingdom, Identity Theft and Fake Cards Top List of Concerns29.7.2021 18:02:00 EEST | Press release
Anomali, the leader in intelligence-driven cybersecurity solutions, today announced availability of its latest survey conducted by The Harris Poll. The study, which gathered responses from more than 1,000 adults aged 18 and over in the United Kingdom, reveals that more than three-quarters of British adults have cybersecurity fears around the use of COVID-19 digital vaccination cards. Additional findings showed which entities respondents believe are responsible for protecting them against cyberattacks and who they believe the most likely culprits will be. A majority of respondents predict that a disruptive cyberattack will follow digital vaccine card adoption, findings also reveal confidence levels when it comes to how prepared the nation is to mount a defense. Among key findings: 76% have cybersecurity concerns related to COVID-19 digital vaccination cards. Identity theft topped the list at 51%, with fake vaccine cards that could be used to hack smartphones (44%) and data breaches (45%
