A novel optical technology based on 690 nm and 850 nm wavelengths to assist needle thoracostomy

Abstract The sensitivity of pneumothorax diagnosis via handheld ultrasound is low, and there is no equipment suitable for use with life-threatening tension pneumothorax in a prehospital setting. This study proposes a novel technology involving optical fibers and near-infrared spectroscopy to assist...
