Abstract
Apparatus ( ) for controlling pressure in a cuff ( ) of an endotracheal tube ( ) a pole mountable housing ( ) within which an inflating medium supply pump ( ) is located for supplying inflating medium to the cuff through a communicating tube ( ) integral with the endotracheal tube ( ) and a delivery tube ( ) from the apparatus ( ). A pressure transducer ( ) connected to the endotracheal tube ( ) by a connecting tube ( ) monitors the pressure of the ventilating medium in the endotracheal tube ( ) for determining transitions from the inspiratory to the expiratory phases of a breathing cycle. A microcontroller ( ) controls the supply pump ( ) for supplying the inflating medium to the cuff ( ) at a first pressure level during the inspiratory phase of each breathing cycle and at a lower second pressure level during the expiratory phase of each breathing cycle.
