Welch Allyn, Skaneateles Falls, NY, has agreed to provide PureSAT SpO2 technology from Nonin Medical, Plymouth, Minn. The arrangement allows Welch Allyn to offer technologies from three pulse oximetry manufacturers as part of its next-generation vital signs device. The new device allows customizable vital signs capture, interval monitoring, and wireless transfer of patient data to the electronic medical record (EMR). The other companies supplying SpO2 technology are Masimo and Covidien.
“Blood oxygen level (SpO2) is an important vital sign that provides feedback on a patient’s overall health status,” said Shawn St. Pierre, senior global category manager, Vital Signs, at Welch Allyn. Providing pulse oximetry solutions from three leading manufacturers, he added, “provides our customers with access to more innovations and the ability to select solutions that best match their performance needs.”
According to Nonin Medical, its PureSAT pulse oximetry technology uses intelligent pulse-by-pulse filtering for precise oximetry measurements—even in the presence of motion, low perfusion or other challenging conditions. Signal processing pre-filters the pulse signals to remove undesirable signals, the company says, then advanced algorithms separate the pulse signals from artifact and interference.
