Study Notes
Changes in Ventilator Measurements
- Reviewing ventilator changes such as PIP (Peak Inspiratory Pressure) and PLT (Plateau Pressure) can provide valuable insights into a patient's respiratory status and the effectiveness of mechanical ventilation
- Closely monitoring ventilator data helps clinicians assess trends and make informed decisions to optimize patient care
Auto-PEEP
- Auto-PEEP is an unintended build-up of positive end-expiratory pressure in the lungs, resulting from incomplete exhalation before the next breath
