Halo ION

A Comprehensive, Personalised, Continuous Patient Score

Halo ION allows clinicians to aggregate trend data from multiple physiologic parameters into a single, continuous patient score which is configured according to hospital protocol.

  • Creates a continuous patient score according to hospital protocol by examining key characteristics of multiple parameters for more personalised care
  • Displays the relative contribution of each parameter, helping clinicians better assess possible causes of patient deterioration as defined by hospital protocol
  • Automates the process by which clinicians assess patient status, reducing cognitive overload and streamlining workflows

Halo Index uses available Masimo parameters and is scalable to include additional information from the patient record. Each parameter’s significance is weighted and combined into the Halo Index — a single displayed number with a range from 0 to 100 that provides a cumulative trending of global patient status. An increase in a patient’s Halo Index may indicate the need for clinicians to more closely assess the patient.
