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.

The AHI System is a proven new clinical tool to detect patient hemodynamic status and predict the risk of hemodynamic instability — bringing new insight to clinicians on the front-line

Thought this was really easy. User friendly. Normally we have in-services; I feel like if you missed that you'd be just fine.

Critical Care/RN



Nurses don’t have time to update patients' vitals and assessments every two minutes. This gives us a way to see that a patient is stable on a regular basis with easy access.

Step Down/RN



This tool can help determine where patients go [in the hospital] and how we should treat them, potentially changing admission flow, freeing up capacity and reducing length of stays.




We have a couple of teams dabbling in "early warning" models, but they have not distilled it down to a single ECG lead!

It would help me assign patients to nurses, knowing where the “hot-spots” are, and guide me to maintain an equal workflow with my nurses.

Critical Care/Charge RN



Just install it and they would start to use it.
