Pulse oximeter showdown: do brands measure up?
NCT ID NCT06635018
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study tested whether different brands of pulse oximeters (the clip-on finger devices that measure oxygen levels) give the same perfusion index readings. 42 healthy adults had readings taken at rest, during finger movements, and with a blood pressure cuff restricting circulation. The goal was to see if device choice affects the numbers, which matters for consistent patient monitoring.
