Abstract:
In patients undergoing endotracheal intubation and mechanical ventilation, damage to the endotracheal tube or inflation line is a potential risk with life-threatening consequences. Although various devices and bite blocks have been developed to secure the endotracheal tube and prevent its dislodgement or damage, they are not suitable for children or newborns. We describe a 1-year-and-2-month-old girl who required long-term endotracheal intubation and mechanical ventilation. The eruption of the lower deciduous incisors caused damage to the inflation line. A mouthguard was not appropriate because her teeth had erupted only slightly, and the retention was insufficient. After collaborating with a dental technician to fabricate a protective device, we were able to provide the optimal treatment while minimizing invasiveness to the patient. It is necessary to collaborate with other professionals as a team to select the optimal medical care tailored to each patient.

Oxygen Delivering System II: Venturi Mask and Transtracheal Oxygen
Venturi Mask
The Venturi mask, named after the Venturi effect, is designed to deliver precise oxygen concentrations. It consists of a large tube with an oxygen inlet that narrows down, causing a pressure drop that pulls air in through adjustable side ports. The mask is a lightweight,...
Endotracheal Tube Extubation
Procedure
Extubation removes the endotracheal tube (ETT) from the patient on mechanical ventilation. It requires a well-coordinated, multidisciplinary approach involving physicians, nurses, respiratory therapists, and other healthcare professionals.
