Asynchrony During Mechanical Ventilation in Patients With Acute Respiratory Distress Syndrome

Descripción detallada

Major patient-ventilator asynchronies have been described during assisted mechanical ventilation in different settings. Few studies have evaluated double cycling in ARDS patient. No clear predictors of this finding beside low tidal volume have been found, and clinical outcome implications have not been addressed. This study has 3 main objectives: evaluate the frequency of double cycling and ineffective efforts, seek for potential predictors and clinical outcomes related to asynchronies. Subjects with less than 72 hours of mechanical ventilation due to ARDS will be recruited. Thirty minutes of mechanical ventilation will be recorded and automatically analyzed with a custom-made program to detect asynchronies. A blood sample will be drawn to measure inflammatory and lung tissue damage biomarkers. Clinical and outcome data will be recorded.
