Effects of Non Invasive Ventilation on Heart Rate Variability After Coronary Bypass Grafting: Comparison Between Different Ventilator
In Brief
A Phase 4 clinical trial evaluating Conventional ventilator and Specific ventilator for Coronary Artery Bypass. Completed, enrolled 10 participants.
Detailed Summary
This is a prospective, quantitative, randomized, crossover study. Were included in this study 10 people in the Intensive Care Unit at University Hospital in Uberlandia, on the first day of the postoperative coronary artery bypass graft (CABG). For data collection was performed randomization on the block (2: 4), to determine the first technique to be used and then a wash-out period of one hour was allowed for the research subject reaches the systemic arterial pressure, heart rate, respiratory rate and oxygen saturation baseline. And after, for cross-over, the second technique was performed. Non-invasive ventilation was performed for 30 minutes each ventilator. All subjects underwent noninvasive ventilation using two models of ventilators, they are conventional (designed for invasive ventilation but is also used in non-invasive ventilation mode) and specific (designed for non-invasive ventilation). Hemodynamic, autonomic and respiratory variables are monitored. We use the hypothesis that non-invasive ventilation performed with two fan models can alter autonomic function and that there is hemodynamic changes related to autonomic function in different ventilators in postoperative coronary artery bypass grafting.

Interventions
A ventilator designed for invasive ventilation was used has mode non-invasive ventilation with leakage compensation (50% of the predetermined tidal volume).
A ventilator was used designed for non-invasive ventilation has an algorithm that calculates the loss of pressure and automatically compensates for leak
