Abstract
Method and device for detecting life-threatening pneumothorax caused by air in the thoracic or chest cavity by passive auditory detection using an array of transducers placed on the patient's chest and operatively connected to a data processing unit. The unit is programmed to filter out sounds not in the harmonic of the bubbling air associated with a pneumothorax. In addition to passive auditory detection ultrasound techniques and radio active gas detection, are shown to be used.
