About this study
To compare a new mode of mechanical ventilation, Automatic Tube Compensation (ATC) with a traditional one, Continuous Positive Airway Pressure(CPAP), on its effectiveness for detecting patients no longer needing mechanical ventilation.
Read the detailed description
The ultimate goal of this proposal is to find the best way to rapidly and safely discontinue mechanical ventilation in patients recovering from respiratory failure.
It is common practice in these patients to perform trials of "spontaneous" breathing while still connected to the ventilator in order to assess their readiness to breathe without assistance. To help with this assessment, new mechanical modes have been incorporated to modern ventilators. A recently developed mode, called Automatic Tube Compensation, is designed for this purpose ("spontaneous" breathing). Whether this method is superior to traditional ones has not been established and the investigators intend to address this question.
The investigators aim to:
- compare Automatic Tube Compensation vs. our traditional mode (Continuous Positive Airway Pressure) during spontaneous breathing trials in their efficacy to identify patients ready be successfully removed from mechanical ventilation
- study which physiologic variables better predict successful discontinuation of mechanical ventilation in these two modes.
The investigators plan to prospectively randomize patients on mechanical ventilation at the point of weaning evaluation, to undergo spontaneous breathing trials with our current ventilatory mode (Continuous Positive Airway Pressure) or the new mode (Automatic Tube Compensation). Based on predefined physiologic and clinical variables, clinicians will decide whether patients are ready to be removed from mechanical ventilation. The proportions of successful discontinuation (no need to reinstitute mechanical ventilation) and the duration of the weaning period in both groups will be compared. During the spontaneous breathing trials, respiratory variables will be measured and compared between patients with successful vs. non successful discontinuation in order to evaluate their predictive value for successful outcome.
Mechanical ventilation is being used increasingly given our growing population with advanced age and multiple co morbidities and the rising volume of aggressive medical procedures. It is well known to be associated with medical complications and high health care costs. Reducing the duration of unnecessary mechanical ventilation while minimizing the risk of premature removal of needed assistance is the final objective of this project. Approaching this goal will decrease the adverse effects of this treatment and the cost of critical care.

What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
automatic tube compensationOther
new mode of ventilation during spontaneous breathing trial. It is a mode of the same device (mechanical ventilator) where the pressure applied by the ventilator varies according to calculations o fthe mechanical properties of the respiratory system automatically performed by the ventilator.
| Study group | Role | What they receive |
|---|---|---|
| Continuous PAP (CPAP) | No intervention | CPAP (continuous positive airway pressure). 5 cm H2O. |
| Automatic tube compensation (ATC) | Experimental | ATC is a new mode of ventilation being compared with traditional one (CPAP). ATC is a mode of ventilation of the same device (mechanical ventilator), not a new device. The pressure in this modes varies according the mechanical parameters of the respiratory system that are automatically calculated by this mode. This is the intervention arm.
