Abstract

A new optical fiber differential pressure sensor has been proposed for neonatal pulmonary ventilation and an experimental investigation on its dynamical metrological performances is here reported. The proposed measurement system has been preliminarily tested by monitoring the mouth pressure during simple respiratory tests in healthy patients and during mechanical ventilation performed by means of a infant ventilator typically used in the neonatal intensive care units; results show that the output of the transducer is consistent with that measured by means of a reference sensor.
