1 Negative pressures generated in our airway model.
Negative pressures generated in our airway model. The triangles indicate the recommended ratio of suction catheter outer diameter to endotracheal tube inner diameter, based on an area/volume ratio of 50% and a diameter ratio of 70%. Since we did not study endotracheal tube (ETT) half-sizes (eg, 6.5 mm), we make no recommendation regarding the 7 French and 5 French suction catheters. Christopher J Russian et al.
