Pulse rate variability as a predictor for length of stay for patients with bronchiolitis in the pediatric intensive care unit
Authors' conclusion
This study demonstrates that the correlation between the PRV and HRV is lower in patients with longer length of stay, suggesting this can be a potential metric for LOS in PICU.
Study context
- Population
- Patients with bronchiolitis admitted to the pediatric Intensive Care Unit (PICU)
- Participants
- 119 patients
- Exposure
- Pulse rate variability (PRV) vs heart rate variability (HRV) correlation in PICU short-stay vs long-stay groups
- Short-stayn = 66reference
- Long-stayn = 53
- Outcome
- Correlation between PRV and HRV parameters and its association with LOS
- Follow-up
- First 12 h after PICU admission
Main finding
As reported in the abstract
Correlation between PRV and HRV parameters
Short-stay
0.72-0.82
correlation
Long-stay
0.29 to 0.67
correlation
Observational data: associations, not effects.
Further findings
HRV vs PRV parameters (SDSD, SDNN, RMSSD, pNN50, SD1, SD2), both length of stay (LOS) groups
- HRV parameters significantly higher than PRV; HRV: 13.72, 10.24, 13.72, 0.77, 9.7, 10.6, and 0.85
- PRV: 5.88, 4.83, 5.88, 0.75, 4.16, 5.28, and 0.85
