perfusieindices
Perfusion indices, or perfusieindices in Dutch, are quantitative measures that describe the level of blood flow or perfusion in tissues, typically at peripheral sites. The term most commonly refers to the Perfusion Index (PI), a metric derived from photoplethysmography (PPG) signals used by many pulse oximeters.
The Perfusion Index is calculated as the ratio of the pulsatile component of the PPG signal to
Clinically, perfusion indices are used as part of non-invasive monitoring to assess peripheral perfusion status, guide
Normal ranges vary by patient and device; typical PI values for adults may span a wide range
