The Efficacy and Safety of Automatic Modes During Respiratory Support After Cardiac Surgery

Aims . To compare the efficacy and safety of semiautonomous Adaptive Support Ventilation (ASV) fully automated (closed-loop, Intellivent-ASV) mechanical ventilation oxygenation versus conventional mode during respiratory support in cardiac surgery patients. Material methods In this study, 40 adult patients were ventilated by managed 8 physicians (control group), whereas other two groups Intellivent-ASV ( n =40) or a semiautomatic ASV =40). The received standard care, except for modes ventilation. Results group, number manual changes ventilator settings was significantly lower: 0 (0–0) 2 (2–3) 4 (3–5) control group P <0.0001). There significant differences duration ICU which 226±31 min (Intellivent group) vs 259±66 271±78 (control) =0.0042; 1–2 =0.0167; 1–3 =0.009). more protective than semiautomated physician-controlled (lower values driving pressure (6 (6–7) cm H O vs. 6 7 (7–9) <0.0001)), tidal volume (7–7.7) (7–8) ml/kg/PBW FiO (26 (24–30)% 34 (30–35)% (30–38)%) with no between paO /FiO frequency undesirable events stay. Conclusion use intelligent technologies makes it possible to interactively individualize support, reducing clinician's involvement process without compromising patient quality
