Abstract
There is described an apparatus () for respiratory support and non-invasive detection of alveolar derecruitment for patients suffering from respiratory failure. Such an apparatus () generally comprises a mechanical ventilator () for inspiration/expiration functions and means () allowing to impose an additional periodic pressure component (Pstim) having a higher frequency than the spectral content of the inspiration/expiration pressure component (Presp). There are provided computing means () to obtain the inspiratory average reactance (Xrs) of the respiratory system of the patient () as the positive end-expiratory pressure (PEEP) varies, in order to detect the presence of alveolar derecruitment. There is also described a procedure allowing to obtain an optimal positive end-expiratory pressure.
