AbstractBag-valve-mask ventilation is a basic airway management technique often used in patients with acute respiratory failure. Although highly effective in providing oxygenation and ventilation, this technique has been associated with gastric regurgitation and tracheal aspiration. In this case, the esophagus visualized with bedside ultrasonography during bag-mask ventilation of an unresponsive and critically ill patient. Images were obtained both with and without cricoid pressure. Additionally, images were obtained during ultrasound-guided probe pressure on the lateral neck. Esophageal insufflation was identified consistently during bag mask ventilation. Cricoid pressure did not prevent esophageal insufflation. Ultrasound-guided probe pressure attenuated esophageal insufflation. This case depicts a unique instance of using a novel method to assess breath delivery during bag mask ventilation of a critically ill patient.
