An Integrated Prehospital Point-of-Care Lung Ultrasound Protocol for Patients With Dyspnea.

We present a time-efficient, clinically integrated lung ultrasound protocol tailored for prehospital use by providers not yet routinely using ultrasound. Specifically designed to support the recognition of pneumothorax and interstitial syndrome, the protocol emphasizes operational feasibility, spectrum-based diagnostic reasoning, and strict time limitations to avoid delays in definitive care. It includes standardized scanning sequences, documentation, and a governance framework for training, certification, and quality assurance. Developed and implemented in an Austrian ambulance service, it may serve as a scalable model for expanding ultrasound access. A prospective registry supports the evaluation of feasibility, image quality, diagnostic yield, and clinical impact.
