When compared with pressure support with zero PEEP, support with 5 cm H2O PEEP led to higher Paw, Pga and PTP, as well as significantly reduced inspiratory trigger delay and abnormal triggers, especially among COPD patients. These findings indicate that use of zero PEEP led to more patient–ventilator asynchronies, so we do not recommend its routine implementation in DTW patients.
