Masimo Rad-8 – Pulse Oximeter With Signal Extraction Technology?


The Masimo Rad-8 is a home pulse oximeter, also known as a blood oxygen meter. Find out everything you need to know about the Masimo Rad-8 today in our review.

What is the Masimo Rad-8?

The Masimo Rad-8 is a blood oxygen meter priced at around $1300 USD. The device lets you monitor blood oxygen levels in a variety of settings – including a hospital, doctor’s office, or your own home. The Rad-8 is typically marketed towards medical professionals, but is now available for anyone to purchase.

Masimo, the makers of the Rad-8, promise “unmatched clinical performance” in a compact design. They claim their system reduces false alarms by 95% without missing true clinical events. Their measuring system, SET pulse oximetry, has also “proven accurate during motion and low perfusion in more than 100 independent and objective studies.”

Masimo Rad-8 Features

The Masimo Rad-8 comes with the following features:

  • Large LED color display easy to read at a distance
  • 2 second average in sleep mode (sleep mode can easily be configured to perform bedside studies)
  • Home Mode allows for safe and accurate blood oxygen monitoring at home
  • RadNet and RadLink to monitor multiple patients simultaneously
  • Perfusion Index (PI) indicates arterial pulse signal strength and may be used as a diagnostic tool during low perfusion
  • Low Signal IQ (SIQ) indicator highlights conditions of low signal quality
  • FastSat system that tracks rapid changes in arterial oxygen levels with high accuracy “unlike any other pulse oximeter”
  • Adaptive Probe Off Detection (APOB) that offers “The best probe off detection of Masimo’s three sensitivity modes”, including APOD, Normal, and MAX sensitivity
  • Adjustable averaging 2 to 16 seconds
  • Nurse call interface
  • Up to 7 hours of internal battery life on a full charge
  • 72 hours of trending memory
  • Horizontal or vertical configurations available
  • Compatible with Philips Vuelink device interface module

The Signal IQ (SIQ) system is particularly important. This system is a signal quality indicator that’s particularly useful during motion and low perfusion situations. With this system, the LED rises and falls with the pulse, with the height indicating signal quality. When the Signal IQ (SIQ) is low, the display will turn red, which indicates suspect SpO2 and Pulse Rate values.

Another key feature is the alarm status indicator, which flashes when an alarm condition is present.

Finally, there’s the Perfusion Index (PI), which indicates arterial pulse signal strength and may be used as a diagnostic tool during low perfusion for the accurate prediction of illness severity.

All of this data is displayed via the Rad-8 back panel, which can be connected to other health platforms for convenient nurse and physician monitoring.

Masimo Rad-8 is available online at a price of $1295 USD.
