During the percutaneous dilatational tracheostomy (PDT), large amount of droplets and aerosols are spread to the environment especially with the effect of ventilation during the dilatation phase. In such cases, it is recommended to take precautions such as masks and goggles or shields to protect practitioners from infection, however it has also been reported that droplets and aerosols can spread to the environment and can go far. Flow controlled ventilation (FCV) with the use of TritubeĀ® and EvoneĀ® could reduce droplet spread during PDT and provide a safer environment while operating on patients with infected airways.
