Patient-ventilator Asynchrony in Conventional Ventilation Modes During Short-term Mechanical Ventilation After Cardiac Surgery

Brazil19 participantsStarted 2017-03-09

Plain-language summary

This study evaluates the effects of VCV, PCV and PSV ventilatory modes during the immediate postoperative period on the variables resulting from regional and global pulmonary electrical impedance and diaphragmatic mobility, as well as perform ventilator synchrony analysis in PSV mode by mechanical ventilator. Half of the participants will receive VCV followed by PSV for weaning, while the other half will receive PCV followed by PSV for weaning.

Inclusion Criteria: * IMC 18.5-29.9 kg/m² * Two thoracic tubes (one mediastinal and one left-sided pleural) * under mechanical ventilation after surgery * submitted to intraoperative extracorporeal circulation Exclusion Criteria: * Over 2h of cardiopulmonary bypass * Over 12h of post-operative mechanical ventilation * Post-operative bleeding above 500 ml in the first hour or above 300 ml in the first two hours * History of special conditions (neuromuscular and chronic pulmonary disease, thoracic deformity, abdominal distension).

What they're measuring

electrical impedance measures

Timeframe: 5 minutes of recording at each step of mechanical ventilation progression before extubation.
