Influence of Respiratory Gases Conditioning on Aerosol Delivery During Invasive Ventilation

Aerosol particles are generated by a vibrating-mesh nebulizer specifically designed for mechanical ventilation

It will be left on during the transfer and the nebulization in group 1

It will be turned off 30 minutes before the nebulization (nebulization ended max 45 minutes after turning off the heated-humidifier).

Streamlined components, specific position for the nebulizer at 30 cm of a V-shaped Y piece

The nebulizer is placed between the filter and the endotracheal tube.
