ICU sedation, delirium & recovery
Clinical validation of video-based vital sign monitoring in the intensive care unit: a prospective cohort study : Clinical validation of video-based vital sign monitoring
Authors' conclusion
Video-based monitoring shows promise for detecting abnormal vital signs in critically ill patients, but improved robustness to motion is needed for reliable clinical implementation.
Study context
- Population
- Heterogeneous population of critically ill ICU patients
- Participants
- 35 ICU patients
- Exposure
- Video-based vs Reference standard
- Outcome
- Agreement of video-based heart rate and respiratory rate with the clinical reference standard (Bland-Altman, ICC, error grid analyses)
- Follow-up
- 24 h
Methodological detailsprospective observational, continuous monitoring for 24 h
- Prospective observational
- Continuous monitoring for 24 h
Main finding
As reported in the abstract
Agreement with reference standard
- Heart rate bias
- 2.1 bpm (limits - 33.6 to 37.7)
- Heart rate within ± 5 bpm
- 81.9%
- Heart rate in error grid zones A/B
- 99.3%
- Heart rate intraclass correlation coefficients (ICC)
- 0.43
- Respiratory rate bias
- - 2.4 breaths/min (limits - 14.3 to 9.5)
- Respiratory rate within ± 3 breaths
- 63.5%
- Respiratory rate in zones A/B
- 87.5%
- Respiratory rate ICC
- 0.41
Observational data: associations, not effects.
Further findings
Factors affecting agreement (generalized estimating equations (GEE))
- High heart rate, atrial fibrillation, norepinephrine administration and movement reduced agreement for heart rate
- Movement reduced agreement for respiratory rate
