Does automatic tube compensation change metabolic parameters when added to pressure support mode during weaning?

چکیده
Introduction Artificial airway increases work of breathing (WOB) during weaning [1] which is one of the reasons for weaning failure [2]. Pressure support ventilation (PSV) decreases WOB and oxygen expenditure by decreasing resistance caused by artificial airway. Because inspiratory flow changes with every breath during PSV, it can not constantly compansate the changes in resistance caused by changes due to patient’s inspiratory effort. Automatic tube compensation (ATC) compensates the imposed WOB due to artificial airway. ATC adjusts the pressure inside the endotracheal tube therefore we hypothesized that when ATC is added to PSV, this compensation becomes better.

Spontaneous breathing test conducted with and without automatic tube compensation does not differ from a metabolic standpoint
Introduction Weaning from mechanical ventilation is defined as the process of release of ventilatory support and how the evaluation of this phase is conducted in the Spontaneous Breathing Test (SBT). One of the most used modes of SBT is the Continuous Positive Airway Pressure (CPAP). However, together with the mechanical ventilation modes it can be used the Automatic Tube Compensation (ATC), wh...
متن کاملComparison between automatic tube compensation and continuous positive airway pressure during spontaneous breathing trials.
BACKGROUND Various methods to perform spontaneous breathing trials (SBTs) exist, but no one method has been shown to be superior. Automatic tube compensation (ATC) is a new and potentially advantageous ventilation mode to use during SBT. We compared ATC to continuous positive airway pressure (CPAP) during SBTs, to determine their efficacy in identifying patients ready to be liberated from mecha...
متن کاملThe Comparison of Automatic Tube Compensation (ATC) and T-piece During Weaning.
OBJECTIVE Automatic Tube Compensation (ATC) is a newly developed mechanical ventilatory support method. The aim of this study was to compare the ATC and the T-piece as a weaning method. METHODS Patients who were treated in ICU with mechanical ventilation for longer than 24 hours were included in this prospective clinical study. Fifty patients were divided into two groups for weaning, ATC or T...
متن کاملAutomatic tube compensation: is it worthwhile?
The influence of the endotracheal tube (ETT) during weaning has been questioned. Concerns about the work of breathing (WOB) imposed by the ETT have led to the use of various corrective methods and ventilatory modes to overcome ETT resistance. Despite the theoretical advantages of different approaches, such as pressure support (PSV) and/or automatic tube compensation (ATC), no methods appear to ...
متن کاملWeaning from mechanical ventilation: why are we still looking for alternative methods?
Most patients who require mechanical ventilation for longer than 24 hours, and who improve the condition leading to the indication of ventilatory support, can be weaned after passing a first spontaneous breathing test. The challenge is to improve the weaning of patients who fail that first test. We have methods that can be referred to as traditional, such as the T-tube, pressure support or sync...
