The Alar Sensor, from Assurance Biosense, moves pulse oximetry away from a patient’s fingertips and puts it on the nasal ala — the fleshy part of the side of the nose. Research indicates SpO2 readings from this location are more accurate and reliable than pulse oximetry devices using clip-on fingertip monitors, according to the company.
Designed to provide continuous non-invasive monitoring, the Assurance Alar Sensor fits to the nasal ala without adhesives and can be easily checked or repositioned.
“IARS is an ideal meeting to first show our Assurance Alar Sensor,” said Andrew E. Kersey, president of Assurance Biosense. “Pulse oximetry is widely considered the fifth vital sign and is a critical component of assessing a patient’s condition. We believe this sensor offers a unique solution to improve upon the measurement of pulse oximetry, providing faster and more reliable detection of oxygen saturation changes than conventional sensors.”
According to Assurance, use of the Alar Sensor in studies at the Hypoxia Research Laboratory at the University of California San Francisco provided consistent accuracy throughout the ranges of 70-80%, 80-90% and 90-100% oxygen saturation.
The Alar Sensor received 510(k) clearance from the FDA in April.
