MightySat® – The only fingertip pulse oximeter to measure five key vital signs: oxygen saturation, pulse rate, breathing rate, perfusion index, and pleth variability index. Powered by Masimo SET® – the same technology used to monitor over 200 million patients at hospitals around the world.1
The same technology trusted by leading hospitals
Performance You Can Depend On:
The Masimo SET® Difference
For more than thirty years, clinicians have trusted Masimo pulse oximetry to help improve patient outcomes. Before Masimo, pulse oximeters were unreliable, providing inaccurate measurements and frequent false alarms. Masimo revolutionized the industry with the development of Signal Extraction Technology® (SET®).
SET® differentiates Masimo from other pulse oximetry technology by using advanced signal processing techniques to separate the arterial signal from sources of noise. This key advantage ensures that Masimo SET® delivers truly accurate measurements—even during conditions that prove challenging for conventional technology, such as movement and cold extremities.
- For All Skin Pigments
Masimo SET® is reliable for all skin color pigmentations.
- Accuracy Anywhere and Everywhere
Masimo SET® provides accurate measurements even in brightly lit environments, such as outdoor sunlight.
- SET® Improves Patient Outcomes
Numerous studies have shown that Masimo SET®, combined with clinical oversight, reduces blindness and eye damage (retinopathy of prematurity, or ROP) in neonates,3 improves critical congenital heart disease (CCHD) screening in newborns,4 and reduces ICU transfers and rapid response team activations on the hospital general floor.5-7
Superior Sensitivity and Specificity
In a comparison of 20 pulse oximeters tested on 70 volunteer subjects during challenging conditions, the Masimo difference was clear: Masimo SET® had greater sensitivity (the ability to detect true oxygen saturation values < 90%) and greater specificity (values ≥ 90%) than all other technologies.9
Alarm Reliability When It Matters Most
Masimo SET® has been shown to deliver superior measurements to other professional-grade pulse oximetry through challenging conditions, including movement and cold hands and fingertips (low perfusion).8
Masimo Signal Extraction Technology® (SET®)
SET® uses advanced signal processing techniques to identify the arterial signal from sources of noise.
Masimo SET® is trusted by care providers around the world to monitor more than 200 million patients each year, and has been shown in more than 100 independent and objective studies to outperform other pulse oximetry technologies.10
Hospital-proven accuracy trusted by doctors and pro athletes
Now available at home
Since the invention of SET®, Masimo has become the leading pulse oximetry brand chosen by hospitals
Provides accurate results when conventional oximeters fail:
Gives the most complete picture of respiratory function
Oxygen saturation in your blood indicates changes in heart and lung function, activity, and altitude*
Understand how fast your heart is beating; changes can indicate stress or exertion*
Breaths per minute
Shows how you are breathing
Blood flow variance
Pleth Variability shows changes in circulation over your breathing cycle. Higher numbers have been associated with lower hydration.
Perfusion Index indicates the strength of blood flow (circulation)
Optimize recovery and readiness to get more out of training
Trend your lung and heart recovery during and after workouts
Target aerobic load during training to stay in the sweet spot
Track hard-to-observe progress like increases in lung efficiency
