Acute Respiratory Distress Syndrome
Conditions
Brief summary
This study will evaluate the correlation between invasively measured parameters (work of breathing/power of breathing, resistance and elastance), derived using esophageal pressure measurements, and their corresponding non-invasive estimated values (noninvasive work of breathing/power of breathing, resistance and elastance), computed using airway pressure and flow measurements only.
Detailed description
This study will evaluate the correlation between invasively measured parameters (work of breathing/power of breathing, resistance and elastance), derived using esophageal pressure measurements, and their corresponding non-invasive estimated values (noninvasive work of breathing/power of breathing, resistance and elastance), computed using airway pressure and flow measurements only. Vent settings will be adjusted to test accuracy over a range of respiratory support conditions.
Interventions
Ventilator settings will be adjusted (vent mode, pressure support/control level, cycling, inspiratory time, mandatory rate).
