Remotely Guided Ultrasound Among Non-Medical Personnel To Assess Normal Lung Parenchyma

This study will assess the feasibility of remotely guided US use by individuals without ultrasound training to assess for normal lung parenchyma in healthy volunteers. The untrained operators (operators) will perform US examinations of lung under the guidance of a medical professional (professional) with experience in ultrasound technique. The professional will guide the operator step by step on how to conduct an US exam of the 'patient's' lung. Images will then be saved and reviewed at a later time by an ultrasound expert to determine quality and clinical functionality in recognizing normal lung parenchyma. This simulation will be analogous to an untrained US operator assessing a potentially ill patient with the assistance of a remotely located physician. An example of this would be an astronaut with respiratory distress after experiencing a rapid decompression event being evaluated by another healthy astronaut by US under the guidance of the flight surgeon at Mission Control.
