Association between hemoglobin concentration and peripheral perfusion index in normovolemic patients: a prospective observational study
Authors' conclusion
Hemoglobin level is independently associated with PI in normovolemic patients.

- Population
- Normovolemic, hemodynamically stable adult ED patients
- Participants
- 90 participants
- Exposure

- Anemicn = 45
- Non-anemicn = 45reference
- Outcome
- Relationship between hemoglobin concentration and peripheral perfusion index (PI)
