NCT03469466

Brief Summary

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.

Outcome Measures

Primary Outcomes (1)

  • Ultrasound Image Quality

    Ultrasound experts will blindly evaluate images obtained from both untrained and trained groups. Using the 'Ultrasound Quality Scorecard', evaluators will assess the quality of the image obtained and the technique carried out to obtain the image. These quality and technique criteria include 'Discernable Lung Parenchyma', 'Presence of A-lines', 'Lack of Obstruction from Rib Shadowing', 'Correct Probe Selection', Correct Depth Setting', 'Correct Gain Selection'. For each criterion (both quality and technique), a binary 'Yes/No' score will be given. Total 'Yes' scores will be summed for each ultrasound exam (minimum 0, maximum 6), with the higher number of 'Yes' responses signifying a higher quality ultrasound exam. Each ultrasound exam will be scored by three separate experts, with the average of the three scores being reported as the 'final score'.
