Abstract

A ventilation apparatus (1) for pulmonary scintigraphy, having an inhalation collector (10) to which an element of inhalation (20), a feeding duct (31), defining a flow of marked aerosol (55), and an outlet duct (32), for disposal of exhaled flow and any aerosol surplus, are connected. The feeding air may be of bi-level type, whereby the air flow rate when breathing out is low, even if always positive. The collector (10) has a first interposition element (21) located at the connection with the air feeding tube (31) that only allows inlet flow towards the patient. A second interposition element (22) is located at the connection with outlet duct (32). The presence of one-way valve/s (21,22) allows to breath the marked aerosol in the bronchial branches of the patient (20) in a way completely natural following the physiologic respiration and avoiding hyper-accumulation of marker in the largest bronchial branches. Scintigraphy is allowed also during a Non Invasive Mechanical Ventilation, carried out through the ventilation apparatus (1).
