Objectives The objective of this study was to determine the feasibility of telementored instruction in bedside ultrasonography ( US ) using Google Glass. The authors sought to examine whether first‐time US users could obtain adequate parasternal long axis ( PSLA ) views to approximate ejection fraction ( EF ) using Google Glass telementoring. Methods This was a prospective, randomized, single‐blinded study. Eighteen second‐year medical students were randomized into three groups and tasked with obtaining PSLA cardiac imaging. Group A received real‐time telementored education through Google Glass via Google Hangout from a remotely located expert. Group B received bedside education from the same expert. Group C represented the control and received no instruction. Each subject was given 3 minutes to obtain a best PSLA cardiac imaging using a portable GE Vscan. Image clips obtained by each subject were stored. A second expert, blinded to instructional mode, evaluated images for adequacy and assigned an image quality rating on a 0 to 10 scale. Results Group A was able to obtain adequate images six out of six times (100%) with a median image quality rating of 7.5 (interquartile range [ IQR ] = 6 to 10) out of 10. Group B was also able to obtain adequate views six out of six times (100%), with a median image quality rating of 8 ( IQR = 7 to 9). Group C was able to obtain adequate views one out of six times (17%), with a median image quality of 0 ( IQR = 0 to 2). There were no statistically significant differences between Group A and Group B in the achievement of adequate images for E‐point septal separation measurement or in image quality. Conclusions In this pilot/feasibility study, novice US users were able to obtain adequate imaging to determine a healthy patient's EF through telementored education using Google Glass. These preliminary data suggest telementoring as an adequate means of medical education in bedside US . This conclusion will need to be validated with larger, more powerful studies including evaluation of pathologic findings and varying body habitus among models.
