Why is bevel of Endotracheal tubes left sided at the proximal tip of the tube-
Endotracheal tubes (ETTs) typically have a left-facing bevel at the tip. ... The bevel is left-facing rather than right-facing to allow a better view of the ETT tip entering the field of view from right to left/ midline and then passing throught the vocal chords. bevel is towards left side.
For easier passage of tube through vocal cords
To prevent occlusion of tip by tracheal wal
For high pressure ventilation
All of the above
