Ventilator dyssynchrony
Educational use only. Not clinically reviewed58-year-old man for Patient-ventilator interaction review and reassessment. About 9 simulated minutes.
What you will practise
- Integrate patient effort with pressure, flow, volume, and delivered-breath observations.
- Review pain, respiratory drive, airway, secretions, circuit, auto-PEEP, gas exchange, and circulation before changing support.
- Classify the bounded flow-starvation and premature-cycling pattern without treating every irregular breath as equivalent.
- Record analgesia-first and respiratory-therapy adjustment intent that matches flow and cycling while preserving lung-protective limits.
- Reassess comfort, effort, graphics, delivered volume, pressures, gas exchange, and circulation after adjustment.
