Auto-PEEP and dynamic hyperinflation
Educational use only. Not clinically reviewed67-year-old woman for Auto-PEEP recognition and reassessment. About 9 simulated minutes.
What you will practise
- Integrate the patient, expiratory flow-time graphic, delivered breathing pattern, pressures, gas exchange, and circulation.
- Use a valid passive expiratory-hold proxy to distinguish set, total, and intrinsic PEEP.
- Classify the bounded obstructive dynamic-hyperinflation pattern and its trigger, pressure, and hemodynamic consequences.
- Record respiratory-therapy and senior-review intent to treat obstruction and preserve more expiratory time while retaining protective guardrails.
- Reassess flow, total and intrinsic PEEP, pressures, triggering, gas exchange, and circulation after adjustment.
