Does Hyperextension of Head Affect Endotracheal Cuff Pressure?

Changes in endotracheal tube cuff pressure during laparoscopic surgery in head-up or head-down position

BACKGROUND The abdominal insufflation and surgical positioning in the laparoscopic surgery have been reported to result in an increase of airway pressure. However, associated effects on changes of endotracheal tube cuff pressure are not well established. METHODS 70 patients undergoing elective laparoscopic colorectal tumor resection (head-down position, n = 38) and laparoscopic cholecystecomy...

Study of endotracheal tube cuff pressure and time of measurement among intensive care units patients

Introduction: The pressure in the endotracheal tube cuff must be kept within an optimal range, to make sure tracheal capillaries circulation still stable during positive ventilation. This is essential to avoid oral and gastric stuffing aspiration Objective: The objective of this study was to assess the endotracheal tube cuff pressure and time intervals measurements among intensive care units...

Linear Correlation of Endotracheal Tube Cuff Pressure and Volume

OBJECTIVES Endotracheal tube cuff (ETTc) inflation by standard methods may result in excessive ETTc pressure. Previous studies have indicated that methods of cuff inflation most frequently used to inflate ETTcs include palpation of the tension in the pilot balloon or injection of a predetermined volume of air to inflate the pilot balloon. If a logarithmic relationship exists between ETTc volume...

Automated control of endotracheal tube cuff pressure during simulated flight.

BACKGROUND Successful mechanical ventilation requires that the airway be controlled by an endotracheal tube (ETT) with an inflatable cuff to seal the airway. Aeromedical evacuation represents a unique challenge in which to manage ETT cuffs. We evaluated three methods of automatic ETT cuff pressure adjustment during changes in altitude in an altitude chamber. METHODS Size 7.5 and 8.0 mm ETTs t...
