Gastric inflation is a significant issue when ventilation of the unprotected airway is performed. The purpose of this study was to evaluate a prototype pressure relief valve with an acoustic expiration control mechanism connected to two different masks. ⋯ Gastric inflation occurred less frequently and to a lesser extent when the valve was connected, going ahead with a trend towards lower tidal volumes. The protective effect of the safety valve may be of benefit even if it leads to smaller tidal volumes.

The superiority of ultrasonic-guided compared with landmark-guided central venous catheter (CVC) placement is not well documented in the Emergency Department. ⋯ Only one single high quality study illustrating that ED ultrasound- versus landmark-guided internal jugular catheter placement had higher success rates with lower complication rates.
