Pressures on endotracheal tube cuffs [PDF]

Anaesthesia, 1981
Summary The general relationships between the pressure inside an endotracheal tube cuff, the pressure exerted by that cuff on the tracheal wall and the airway pressure have been re‐examined in a model system. In relatively recent literature, the tracheal wall pressure at a given cuff volume has been calculated as the difference ...

Microstructure Evolution during Fabrication of Zr-2.5Nb Pressure Tube (Ⅰ)—α/β Phase Transformation

Yuanzineng kexue jishu, 2023
Zr-2.5Nb pressure tube is one of the most important components of the fuel channel in the CANDU reactors. The α/β phase transformation of Zr-2.5Nb during pressure tube fabrication is much more complex than that in single α phase zirconium alloys for fuel

Pressure Analysis in the Draft Tube of a Pump-Turbine under Steady and Transient Conditions

Energies, 2021
Pumped-storage power stations play a regulatory role in the power grid through frequent transition processes. The pressure pulsation in the draft tube of the pump-turbine under transient processes is important for safe operation, which is more intense ...

Experimental Assessment of Cuff Pressures on the Walls of a Trachea-Like Model Using Force Sensing Resistors: Insights for Patient Management in Intensive Care Unit Settings

Sensors, 2022
The COVID-19 outbreak has increased the incidence of tracheal lesions in patients who underwent invasive mechanical ventilation. We measured the pressure exerted by the cuff on the walls of a test bench mimicking the laryngotracheal tract. The test bench

Accuracy of pilot balloon palpation for cuff pressure assessment in small versus large sized tubes: a prospective non-randomized observational study

Scientific Reports, 2023
Pilot balloon palpation is still a commonly used method to evaluate cuff pressure of the endotracheal tube after intubation. This study determined whether the size of the tracheal tube influenced the accuracy of pilot balloon palpation.
