UNDERLYING SCIENCE

AHI and AHI-PI are novel FDA-cleared analytics that measure real-time hemodynamic status and identify emerging and increased risk of future hemodynamic instability.

HEMODYNAMIC STATUS

Hemodynamic status is a continuum ranging from a stable and healthy state where a body’s systems are providing adequate oxygenated blood to perfuse the tissues to an unstable state where failure to provide adequate perfusion can lead to multi-organ failure and death.

For decades, the practical clinical standard for identifying hemodynamic instability was out-of-range hemodynamic vital signs (heart rate and blood pressure).  Despite their proven clinical importance, raw vital sign data has its drawbacks:

  • Burdensome to gather, trend and interpret
  • Does not provide objective predictive information
  • Monitored intermittently and irregularly
  • Inherently noisy
  • Prone to error

Some hospitals are trying to extract timely and actionable information from electronic health record-based analytics. Unfortunately these suffer from delayed and intermittent inputs, cause nurse burden, and have demonstrated unclear value.

To ensure broad applicability to patient care across the hospital and easy implementation into clinical workflows, Fifth Eye minimized the number of sensors required to produce actionable information.

By leveraging known relationships between cardiac rhythm, heart rate variability, and patient compensation, clinically-validated AHI sifts through the noise to spot:

  • Hidden ECG patterns associated with hemodynamic instability
  • Emerging signs of shock
  • Autonomic nervous system compensation

Using only a single existing lead of streaming ECG and no manual inputs, the AHI analytics monitor the autonomic nervous system compensating for changes in hemodynamic status and predict emerging hemodynamic instability.
