Entrainment-Based Mechanical Ventilation to Improve Patient-Ventilator Synchrony
Abstract
BACKGROUND AND SIGNIFICANCE Entrainment-based ventilation is a new mode of mechanical ventilation based on the classical physics theory of mutual entrainment between coupled oscillators. Typically, the entrained inspiratory activity may precede or lag behind machine inflation depending on whether spontaneous respiratory frequency is higher or lower than the ventilator frequency.
HYPOTHESIS The investigators anticipate that the results of the study will help to improve the interaction of patients with the mechanical ventilator thereby minimizing the risks of mechanical ventilation in future. The investigators believe the potential benefits significantly outweigh the potential risks.
RESEARCH STUDY DESIGN AND METHODS This is a prospective study and single site. Twenty mechanically ventilated patients, stable on their current vent settings and are capable of triggering the ventilator in the SICU, MICU, CCU and Cardiac and Neuro Surgery ICUs at BWH will be recruited.
After obtaining informed consent a respiratory real-time data monitor will be placed between the artificial airway and the Y piece of the ventilator circuit. Baseline mechanical ventilation data with conventional pressure-limited assist/control ventilation mode will then be collected for a 4-hour period. The patients will then be transitioned to pressure-limited entrainment-based ventilation for a 4-hour period. Baseline ventilation monitoring will be carried out either immediately preceding or immediately following…
How strong is the evidence?
Evidence Hub reads this as a randomized trial, done in people. Its evidence level is 3 of 5 (Moderate · trial / cohort / secondary analysis). Trials without a large randomized design, cohorts and secondary analyses give moderate evidence. Reported size: 1 participants or records.
