Automatic Tube Compensation vs. Pressure Support Ventilation During Spontaneous Breathing Trials in Adults

Официальное название

Automatic Tube Compensation vs. Pressure Support Ventilation During Spontaneous Breathing Trials in Critically Ill Adults: A Cluster-Randomized, Cluster-Crossover Trial

Обзор

For patients requiring mechanical ventilation, spontaneous breathing trials (SBTs) are conducted to determine if it is safe to remove the breathing tube. There are multiple methods for conducting SBTs. The purpose of this study is to compare the effects of 2 methods, pressure support ventilation (PSV) versus automatic tube compensation (ATC), on successful extubation for critically ill adult patients who received mechanical ventilation for over 24 hours.

Подробное описание

The delivery of pressure support through the ventilator can be fixed using the pressure support ventilation (PSV) mode or variable using the automatic tube compensation (ATC) mode. Similar to PSV, ATC provides pressure support but dynamically adjusts it to compensate the resistive work of breathing and the mechanical load on respiratory muscles imposed by an artificial airway, such as an endotracheal or tracheostomy tube. Although both ATC and PSV are licensed and used in clinical practice, the optimal method to deliver pressure support during a spontaneous breathing trial (SBT) remains unknown. At Rush University Medical Center, ATC has been used for SBTs for over a decade. However, given the growing popularity of PSV, the SBT protocol was updated and now approves the use of PSV and ATC as standard care for SBT without making a recommendation for a preferred mode. The choice between PSV and ATC during SBT is left to the discretion of the clinician, reflecting the ongoing equipoise in the conduct of the SBT. As patients will be exposed to the potential benefits and risks of PSV or ATC under this change in clinical practice, the investigators are conducting a cluster-randomized cluster-crossover trial to compare the mode's effect on successful extubation.

Вмешательства

• Другое Pressure Support Ventilation (PSV)
  Spontaneous breathing trials will be conducted using the mode pressure support ventilation (PSV) with settings of a pressure support of 5 cmH2O and positive end expiratory pressure (PEEP) 5 cmH2O.
• Другое Automatic tube compensation (ATC)
  Spontaneous breathing trials will be conducted using the mode automatic tube compensation (ATC) with settings of 100% tube compensation and a positive end expiratory pressure (PEEP) of 5 cmH2O.
