Performance of the Hypotension Prediction Index as an indicator of hypotensive haemodynamic instability in surgical patients
Authors' conclusion
The Hypotension Prediction Index predicts the upcoming hypotensive haemodynamic instability events with high accuracy.
Study context
- Population
- Cardiac and non-cardiac surgical patients monitored with Hypotension Prediction Index (HPI) technology
- Participants
- 1,683 participants
- Exposure
- Invasive A-line vs Non-invasive finger cuff
- Invasive A-linen = 871
- Non-invasive finger cuffn = 812
- Outcome
- Proportion of HPI alerts (thresholds 85 and 50) followed by haemodynamic instability (MAP < 65 mmHg, SVV ≥ 13%, CI ≤ 2 L·min-1·m-2, SVR ≤ 800 dyn·s·cm-5)
- Follow-up
- 15 min
Main finding
As reported in the abstract
HPI alerts followed by haemodynamic instability
HPI threshold 85
HPI threshold 50
Observational data: associations, not effects.
