Airvo 3 Respiratory Rate Validation Study

Validating the Accuracy of the Airvo 3 Device for Continuous Respiratory Rate Monitoring in Healthy Adults and Chronic Obstructive Pulmonary Disease (COPD) Patients: Comparison With a Reference Benchmark

This is a clinical performance testing to validate the accuracy of the Airvo 3 device with respiratory rate algorithm manufactured by Fisher & Paykel Healthcare for continuous respiratory rate monitoring.

The Airvo 3 device is intended to provide high flow warmed and humidified respiratory gases for administration to spontaneously breathing patients in hospitals and sub-acute facilities. The device has recently been updated with a new feature which allows continuous monitoring of patient's respiratory rate during nasal high flow therapy. This study, therefore, aims to validate the accuracy of the respiratory rate output of the Airvo 3 device. The respiratory rate output of the Airvo 3 device will be compared to the respiratory rate output of a gold standard reference device (capnography) in healthy volunteers and COPD patients to determine the level of agreement between the respiratory rate outputs of the two devices. In addition, the respiratory rate output of the Airvo 3 device will be compared to the respiratory rate output of a United States Food and Drug Administration (U.S. FDA) cleared pulse oximeter in healthy volunteers and COPD patients to determine the level of agreement between the respiratory rate outputs of the two devices.
