BACKGROUND: Recent reports demonstrate high diagnostic accuracy of lung ultrasound for evaluation of dyspnea. We assessed the feasibility of training internal medicine residents in lung ultrasound with a pocket ultrasound device.

It is feasible to incorporate intraosseous use during medical emergency team calls. Intraosseous had significantly higher first-pass success rates and faster placement compared with central venous catheters. Intraosseous operators reported high satisfaction and confidence in its use. Prospective randomized studies comparing intraosseous and central venous catheter are warranted.
