Abstract
Remotely Piloted Aerial Systems (RPAS) are poised to revolutionize healthcare in out-of-hospital settings, either from necessity or practicality, especially for remote locations. RPAS have been successfully used for surveillance, search and rescue, delivery, and equipping drones with telemedical capabilities being considered. However, we know of no previous consideration of RPAS-delivered tele-ultrasound capabilities. Of all imaging technologies, ultrasound is the most portable and capable of providing real-time point-of-care information regarding anatomy, physiology, and procedural guidance. Moreover, remotely guided ultrasound including self-performed has been a backbone of medical care on the International Space Station since construction. The TeleMentored Ultrasound Supported Medical Interventions Group of the University of Calgary partnered with the Southern Alberta Institute of Technology to demonstrate RPAS delivery of a smartphone-supported tele-ultrasound system by the SwissDrones SDO50 RPAS. Upon receipt of the sanitized probe, a completely ultrasound-naïve volunteer was guided by a remote expert located 100 km away using online video conferencing (Zoom), to conduct a self-performed lung ultrasound examination. It proved feasible for the volunteer to examine their anterior chest, sides, and lower back bilaterally, correlating with standard recommended examinations in trauma/critical care, including the critical locations of a detailed COVID-19 lung diagnosis/surveillance examination. We contend that drone-delivered telemedicine including a tele-ultrasound capability could be leveraged to enhance point-of-care diagnostic accuracy in catastrophic emergencies, and allow diagnostic capabilities to be delivered to vulnerable populations in remote locations for whom transport is impractical or undesirable, speeding response times, or obviating the risk of disease transmission depending on the circumstances.
