VentilO versus clinician ventilator settings after cardiac surgery

Frequency of Respiratory Acidosis in the Intensive Care Unit After Postoperative Cardiac Surgery. Impact of Using VentilO Application

NA · Laval University · NCT06826794

This will see if using the VentilO app to set ventilator rate and breath size right after ICU admission reduces episodes of respiratory acidosis in intubated adults after heart surgery.

What this trial studies

This is a randomized, open-label comparison of initial ventilator settings chosen by clinicians versus settings recommended by the VentilO application for adults intubated immediately after cardiac surgery. Patients are ventilated in controlled modes (Assist Control or SIMV) and the study compares respiratory rate, tidal volume, and resulting minute ventilation between the two approaches. The primary outcome is the frequency of respiratory acidosis during early ICU care. The trial is conducted at a single tertiary cardiac ICU in Québec.

Who should consider this trial

Good fit: Adults over 18 who are intubated and admitted to the ICU immediately after any cardiac surgery, receiving controlled-mode ventilation (Assist Control or SIMV) with height and weight documented are ideal candidates.

Not a fit: Patients who are mainly breathing spontaneously on arrival, are extubated on arrival, or lack documented height/weight are excluded and unlikely to benefit from the intervention.

Why it matters

Potential benefit: If successful, VentilO-guided settings could reduce episodes of respiratory acidosis and improve early ventilator management for post-cardiac surgery patients.

How similar studies have performed: Other decision-support tools for ventilator settings have shown mixed improvements in parameter consistency and gas control, but VentilO-specific evidence is limited and the application is relatively novel.
