SYSTEMS AND METHODS FOR LUNG IMAGING, PNEUMOTHORAX DETECTION AND ENDOTRACHEAL TUBE INSERTION

摘要

An ultrasound system and method for ascertaining or predicting normal and pathological lung states by determining the presence, the absence or intermediate degrees of lung sliding that is exhibited during respiratory cycles is disclosed. The ultrasound system and method employs. A-mode scanning to generate echogenic histogram patterns to discern whether a lung has an echogenic pattern indicative of a normal lung or that indicative of a pneumothorax or a haemothorax. A video laryngoscope having a blade-located camera and an optical calibrator connected with the camera to configured to emit visible lines separating by a known distance onto the tracheal region in view of the camera is further disclosed. An image of the tracheal region and lines may be conveyed to a video screen from which the dimension of the tracheal orifice may be estimated. Endotracheal tubes may be then selected having a size that may be slidably accommodated through the estimated tracheal orifice diameter.
