Improved tidal volume at the same differential pressure indicate an improvement in lung compliance. However, more recent evidence reveals that neither V T scaled to PBW nor plateau pressure are adequate surrogates for predicting outcomes. The risk of developing side effects is higher in patients with severe lung disease, increased respiratory drive neurological or metabolic , increased dead space, and prolonged time constants Tables 4 and 5. Epub Feb 9. Alveolar Ventilation V A is the amount of gas which reaches functional respiratory units ie, alveoli per minute. If a patient is at risk for developing lung injury, where does noninvasive ventilation NIV come into this?

Chatburn RL. However, with technological advances, today's mechanical ventilators now have advanced graphic packages that depict the waveforms in great detail. Discussion Kallet: Great presentation by both of you.
The patient is obviously laboring to breathe with use of accessory muscles and is less responsive than he was on admission. However, after recruitment, optimal PEEP can maintain an 'open lung' and prevent or minimise subsequent collapse. Animal studies have shown that high V T ventilation increases levels of pro-inflammatory mediators, leads to pulmonary edema, and causes increased alveolar-capillary permeability and structural abnormalities.
