How do I know what size ETT for my neonate?
Endotracheal tube (ETT) internal diameter in millimetres can be calculated as gestational age in weeks divided by 10. Typically, a 2.5 tube is appropriate for infants <1kg weight, a 3.0 tube for infants weighing 1-2 kg, a 3.5 tube for infants 2-3 kg, and a 3.5 or 4.0 tube for infants over 3 kg.
How do you calculate ETT tube size?
Pediatric tubes are sized using the equation: size = ((age/4) +4) for uncuffed ETTs, with cuffed tubes being one-half size smaller.  Typically a pediatric ETT is taped at a depth of 3 x the tube size in a child (i.e., a 4.0 ETT commonly gets taped at around 12cm depth).
What ET tube is used for neonatal patients?
Endotracheal tube (ETT) size Using this rule, a 2.5mm ID endotracheal tube would be used for an infant born at 25 weeks’ gestation, a 3.0mm ID for an infant born at 30 weeks and a 3.5mm ID for an infant born at 35 weeks’ gestation.
How big should an ET tube be for a newborn?
Use age for picking an ET tube size for infants and children. You need to be careful when sizing an ET tube on a child. Because their bodies are so small, you need to be more exact in your measurements than with adults. With this in mind, size ET tubes based on the child’s specific age: Newborn: 2.5 – 4.0 mm
What is the internal diameter of an ett?
Select an uncuffed tube with an internal diameter of 3.5 mm for infants up to 1 year of age. A cuffed ETT with an internal diameter of 3.0 mm may be used for infants more than 3.5 kg. and <1 year. ID stands for internal diameter.
What is the average size of a neonatal feeding tube?

Term Neonates: Average weight: 3.3 kg Tube size: 3.0 mm cuffed Tube depth: 9 -10 cm Miller blade size: 0 LMA size: 1 6 Months: Average weight: 7.5 kg Tube size: 3mm cuffed Tube depth: 10 cm Miller blade size: 1 LMA size: 1.5 1 – 2 Years: Average weight: 9 – 11.5 kg Tube size: 3.5 mm cuffed Tube depth: 10 – 11…
How big of an ett do I need for a 1 year old?
Notes Select an uncuffed tube with an internal diameter of 3.5 mm for infants up to 1 year of age. A cuffed ETT with an internal diameter of 3.0 mm may be used for infants more than 3.5 kg. and <1 year. ID stands for internal diameter.
