document: A novel preterm respiratory mechanics active simulator to test the performances of neonatal pulmonary ventilators A patient active simulator is proposed which is capable of reproducing values of the parameters of pulmonary mechanics of healthy newborns and preterm pathological infants . The implemented prototype is able to : -LRB- a -RRB- let the operator choose the respiratory pattern , times of apnea , episodes of cough , sobs , etc. , -LRB- b -RRB- continuously regulate and control the parameters characterizing the pulmonary system ; and , finally , -LRB- c -RRB- reproduce the attempt of breathing of a preterm infant . Taking into account both the limitation due to the chosen application field and the preliminary autocalibration phase automatically carried out by the proposed device , accuracy and reliability on the order of 1 % is estimated . The previously indicated value has to be considered satisfactory in light of the field of application and the small values of the simulated parameters . Finally , the achieved metrological characteristics allow the described neonatal simulator to be adopted as a reference device to test performances of neonatal ventilators and , more specifically , to measure the time elapsed between the occurrence of a potentially dangerous condition to the patient and the activation of the corresponding alarm of the tested ventilator
