Description
Calculations are based on standard endotracheal tubes. The volume is
estimated as the cylinder of the given diameter and typical length of a tube
of given size.
Usage
1
ett_vol_ml(diameter_mm)
Arguments
diameter_mm
The internal diameter of the endotracheal tube in
millimeters. Sizes between 2.0 and 8 are offered. Half sizes between 2.5
and 6 are accepted.
Value
Volumes of each given ETT in cubic millimeters
