Focused Cardiac and Lung Ultrasound in Anesthesia/Critical Care - The Role of Self-directed Simulation-assisted Training Compared to a Traditional Supervised Approach

All participants will attend an ultrasound introductory course (lectures and illustrative interactive cases). Participants randomized to the intervention group will undergo a completely self-directed lung and focused cardiac ultrasound curriculum. * A set of video-lectures on how to perform US on a critically ill patient (video-tutorials on image acquisition, troubleshooting, and pitfalls) will be provided. * Participant will have access to an ultrasound simulator. * Finally, participants in the intervention group will be asked to perform self-directed lung and focused cardiac ultrasound examinations on critically ill patients. An investigator will supervise the sessions but will not interfere with the self-learning process. \- To support their learning, trainees will have access to on-line virtual FCU and LUS modules created by the Toronto General Hospital Department of Anesthesia Perioperative Interactive Education (http://pie.med.utoronto.ca/TTE/index.htm).

All participants will attend an half-day ultrasound introductory course. * Participants randomized to the conventional group will initially attend 2-hour hands-on session on healthy volunteers, fully supervised by an expert critical care ultrasonographer (acquisition of basic knowledge with US machine settings and probe positioning and orientation, normal view acquisition, and identification of normal anatomical structures and landmarks). * Subsequently, participants will attend a 3-hours hands-on session on critically ill patients, fully supervised by an expert critical care ultrasonographer.
