The turbine pneumotachometer is used to measure which of the following ventilatory parameters?

The turbine pneumotachometer is designed to measure airflow and, by integrating that flow over time, derive volumes. As air moves through, the turbine spins faster or slower in proportion to the flow rate, and a sensor translates that into a flow signal. By summing the flow across the breath, you obtain volume; from a full inspiration to a full expiration, you get tidal volume and, with maximal effort, vital capacity. Oxygen saturation is tracked with pulse oximetry, inspiratory pressure is measured with a pressure sensor, and airway resistance requires a pressure–flow relationship across the airways—data not provided by a turbine alone.
