Getting to Know Your System

Now There's a Way to Help Safeguard at Home


Masimo SafetyNet Alert, an oxygen monitoring and intervention system, offers access to hospital-grade, clinically proven SET® technology at home.

As oxygen levels decline and if severity increases, an escalating alert system notifies you and your designated emergency contacts to help take action.

The system includes a bedside station, two disposable fingertip sensors (each intended for up to a total of 96 hours of continuous use*), a reusable chip, and a downloadable app available at no charge for your smartphone.

*Based on 96 hours of sensor battery life. Remove chip when not in use.

Escalating Alerts Raise Awareness and Drive Action When Help Is Needed

  • Automatic alert system escalates as oxygen levels decline; alerts are sent to you, and then your loved ones
  • Comfortable to wear and easy to use
  • May benefit those with breathing issues, including people taking opioids or other sedating drugs to manage pain, with respiratory conditions such as asthma, COPD, lung disease or recovering from COVID-19.1-2 
  • Uses Masimo SET® Measure-through Motion and Low Perfusion™ technology, the same proven technology used in hospitals to monitor more than 200 million patients annually.3
