The Effect of Cycling Off Criteria During Pressure Support Ventilation in Chronic Obstructive Pulmonary Disease (COPD) Patients

The Effect of Cycling Off Criteria During Pressure Support Ventilation in Chronic Obstructive Pulmonary Disease (COPD) Patients

The investigators' aim is to study the effect of cycling off criteria during pressure support ventilation in COPD patients at two levels of PEEP and PSV.

In this study two levels of cycling off criteria at two levels of PEEP and PSV were tested in term of gas exchange, respiratory mechanics, work of breathing and patient comfort.

Inclusion Criteria:

• Stable COPD patients during invasive mechanical ventilation

Exclusion Criteria:

• Hemodynamic instability,
• Paralysis
