Synchrony, Pressure Support Ventilation
Brief summary
Pressure Support Ventilation use Expiratory triggering sensitivity(Esense) to transfer inspiration to expiration,the value of Esense is fixed.That may lead to asynchrony between humans and ventilators,making people uncomfortable and prolonging weaning time.Some ventilators have auto cycle function Based on curves of pressure on respiratory patterns,it will make the transforming more synchrony with humans.Our prospective observational study will prove the superiority of the auto cycle function.
Detailed description
From August 31st 2016 to August 31st 2017, all ARDS 、COPD and postoperative patients admitted to the ICUs will be enrolled. The demographic characteristics, diagnosis, formerly medical history, Ventilator indications, Ventilator data, other respiratory treatments, weaning outcome and 28 day mortality will be recorded
