Acute Respiratory Distress Syndrome

Acute respiratory distress syndrome, PiCCO, mechanical power
Brief summary
Based on PiCCO combined with MP, the optimal mechanical power setting of the ventilator for ARDS patients in normal supine/prone position is determined to reduce the damage to lung function during mechanical ventilation. By detecting peripheral serum NLRP3 and related inflammatory markers in ARDS patients, the relationship between NLRP3 and lung injury caused by mechanical ventilation was studied.

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| mechanical power | Data were obtained within the first hour post-intubation, at 8:00 AM (±1 h) daily for the subsequent three consecutive days, and during position changes (prone to supine or supine to prone) within these three days. | deep sedation, elimination of spontaneous breathing, measurement via ventilator.Mechanical power (MP) was calculated from the median ventilator parameters via the following equation: mechanical power (J/min) = 0.098× RR × Vt × (PIP - 0.5(Pplateau-PEEP)), where PIP =peak inspiratory pressure. The MP was normalized to the predicted body weight (norMP) = MP/PBW,where PBW was the predicted body weight measured in kilograms. |
