Continuous non-invasive measurement of tidal volume and minute ventilation using a smart nasal cannula
Abstract This study evaluated whether a newly developed smart nasal cannula can accurately and continuously measure tidal volume (VT) and minute ventilation (VE) in adults across a wide range of respiratory patterns using a validated benchtop model. The device uses nasal pressure and flow dynamics, derived from RPD (respiratory pressure difference) sensors, to estimate VT […]
