Over 100 independent and objective studies have shown that Masimo SET? outperforms other pulse oximetry technologies.1

  • On a post-surgical unit it was found that:
    • Rescue calls and ICU transfers were reduced by 65% and 48%, respectively, after the implementation of continuous surveillance monitoring with Masimo SET?.2
    • Over five years, clinicians achieved their goal of zero preventable deaths or brain damage due to opioids.3
    • Over ten years, clinicians maintained a 50% reduction in unplanned transfers and a 60% reduction in rescue events, despite increases in patient acuity and occupancy.4
  • In a PACU, Masimo SET? had a greater than 50% reduction in false alarms compared to other pulse oximetry technology.5
  • In a study of 122,738 infants, critical congenital heart disease (CCHD) screening sensitivity increased from 77% to 93% with the combined use of Masimo SET? and clinical assessment.6
  • In a study of 39,821 infants, CCHD screening sensitivity increased from 63% with physical exam alone to 83% with physical exam and Masimo SET? pulse oximetry.7
  • In two NICU settings, Masimo SET?, coupled with changes in clinical practice, showed significantly reduced rates of severe retinopathy of prematurity (ROP) and decreased the need for laser treatment.8,9
  • Researchers showed time to reliable oxygen saturation readings during neonatal resuscitation was approximately 50 seconds faster using Masimo SET? than using other pulse oximetry technologies.10
“I saw and was conquered. I was not able to defeat the Masimo SET? pulse oximeter using all the motion and low pulse tricks I know. This technology is most impressive and should be available in all oximeters.”

Sensitivity vs. Clinical Assessment Alone

Improved Critical Congenital Heart Disease Screening  Sensitivity vs. Clinical Assessment Alone
  • When combined with clinical assessment, Masimo SET? improved critical congenital heart disease (CCHD) screening sensitivity to 93%6

Retinopathy of Prematurity

Severe Retinopathy of Prematurity Rate

Severe Retinopathy of Prematurity Rate
  • Masimo SET?, coupled with changes in clinical practice, led to a significant reduction in rates of severe retinopathy of prematurity (ROP)8

Performance During Motion and Low Perfusion

Masimo - Performance through Low Performance Chart
  • Masimo SET? had 3% missed true alarms and 5% false alarms versus 43% and 28%, respectively, using competitor technology11*

*Results shown are calculated by combining sensitivity and specificity outcomes of machine-generated and volunteer-generated motion.
