Pressure changes during tracheal suctioning--a laboratory study.


Suctioning is essential in managing tracheal tubes, but also has drawbacks. Using a bench model, we demonstrated the extent and time course of pressure changes during suctioning, examined their relationship with tracheal tube and catheter diameters and assessed the effects of artificial 'sputum' and of compensatory gas flow in the system. We suctioned at… (More)
