Adults:
We must select the largest diameter ETT that can be tolerated for adults.
A size 7.5-mm cuffed ETT is well tolerated by most adult female patients.
A size 8.0-mm cuffed ETT is well tolerated by most adult male patients.
Pediatrics:
An uncuffed ETT should be used for children under the age of 8 years.
The formula most commonly used is:
ETT size(mm) = (Age[yr] +16)/4
To estimate the depth of insertion for a child older than 2 years:
Depth of insertion = 3× internal diameter of the ETT
