The predictive value of perfusion indices in the triage and clinical management of carbon monoxide poisoning
An erratum to this article was published (J Clin Monit Comput, Dec 2025 ↗)
Authors' conclusion
Perfusion indices, especially PI, may reflect changes in COHb levels and could provide additional information to support triage and monitoring in CO poisoning.
Study context
- Population
- Patients aged 18 years and older diagnosed with CO poisoning, January 2019 to May 2023
- Exposure
- HBOT vs NBOT
- Outcome
- Whether perfusion indices (PI, PVI) can assist in triage and monitoring of CO poisoning
Methodological detailsconsecutive enrolment
- Consecutive enrolment
Main finding
As reported in the abstract
AUC of PI-1 in predicting the necessity for HBOT
0.935
Observational data: associations, not effects.
Further findings
Change after treatment (perfusion index (PI), pleth variability index (PVI), lactate, carboxyhemoglobin (COHb)) · after 60-min oxygen therapy
- PI increased, and PVI, lactate and COHb decreased significantly in both treatment groups
- P < 0.001 for all
