1. An apparatus (1) for respiratory support and non-invasive detection of alveolar derecruitment for patients (2) suffering from respiratory failure, said apparatus (1) comprising means (3) for carrying out respiratory functions and comprising conduits (5, 6, 7, 20, 21) for the passage of air from and to the airways of a patient (2), and further comprising transducers of pressure (9, 10) to electric signals, transducers of flow (8) to electric signals and computing means (12, 412) for processing said electric signals so as to obtain a value of the inspiratory reactance (Xrs) indicative of the state of pulmonary derecruitment, which corresponds to a point of maximum respiratory reactance.
