This study looked at whether a narrower oxygen saturation target range helps an automated oxygen control system work better for very low birth weight infants on breathing support. Eleven babies were randomly assigned to either a 3% or a shifted 3% target range. The goal was to se…

This completed study with 15 healthy volunteers tested how breathing low-oxygen and high-carbon-dioxide gas mixtures for six minutes changes heart function and blood flow. Researchers measured cardiac output and perfusion index under three conditions: low oxygen alone, high carbo…

This study compared blood oxygen readings from three different smartwatch models against a standard medical pulse oximeter. Eighteen healthy adults breathed low-oxygen mixtures to simulate hypoxia while wearing a smartwatch and a reference oximeter. The goal was to see how well t…

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 circulat…

This study checked if a Samsung smartwatch can accurately measure blood pressure over a long period. Researchers compared the smartwatch's readings to a standard medical device in 42 healthy adults. The goal was to see if smartwatches could be a reliable tool for tracking blood p…

This study looked at whether the finger you put a pulse oximeter on affects the oxygen reading. 24 healthy adults had their oxygen levels measured during short-term low oxygen and high carbon dioxide conditions. The goal was to see if choosing a specific finger could make reading…
