Wearable devices may provide a promising alternative solution for measuring RV. However, more robust studies in non-stationary conditions are needed using appropriate methodology in terms of number of subjects involved, acquisition and analysis techniques implied.

Use of video laryngoscopes by prehospital providers in Level C PPE did not result in faster endotracheal intubation than use of a Macintosh laryngoscope. The King Vision video laryngoscope, in particular, performed at least as well as the Macintosh laryngoscope and was reported to be easier to use. Yousif S , Machan JT , Alaska Y , Suner S .

Background:Saudi Board of Emergency Medicine (SBEM) graduates are involved in a 1-month rotation in emergency medical services (EMSs) and disaster medicine. The purpose of this study was to evaluate change in knowledge and attitude of EM residents after the introduction of the EMS and disaster medicine rotation.Materials and Methods:The study included 32 3rd-year SBEM residents. A pretest/posttest design and a five-point Likert scale were used. The data included a response to a questionnaire developed by EMS and disaster experts. The questionnaire was distributed on the 1st day of the rotation and 45 days after. Satisfaction questionnaires were distributed after the rotation. The data were analyzed using SPSS 20.Results:Twenty-five residents responded to the satisfaction survey (75%). The overall satisfaction with the course modules was high; the course content showed the highest level of satisfaction (96%), and the lowest satisfaction was for the air ambulance ride outs (56%). The results of the pre-/post-test questionnaire showed an increase of 18.5% in the residents mean score (P < 0.001). In the open-ended section, the residents requested that the schedule is distributed before the course start date, to have more field and hands-on experience, and to present actual disaster incidents as discussion cases. The residents were impressed with the organization and diversity of the lectures, and to a lesser extent for the ambulance ride outs and the mass casualty incident drill l. Seventy-one percent indicated that they would recommend this course to other residents.Conclusion/Recommendation:This study showed that a structured course in EMS and disaster medicine had improved knowledge and had an overall high level of satisfaction among the residents of the SBEM. Although overall satisfaction and improvement in knowledge were significant, there are many areas in need of better organization.
