| Popis: | To evaluate the cardiopulmonary effects, especially the end-expiratory lung volume (EEV) and ventilation inhomogeneity during diminished early expiratory flow ventilation (DEEF), which resembles pursed-lips breathing, with the conventional intermitent positive pressure ventilation (IPPV) in postoperative mechanically ventilated patients with chronic obstructive pulmonary disease (COPD). A prospective study measuring cardiopulmonary parameters during IPPV, DEEF, and positive end-expiratory pressure (PEEP) as a control mode. In the PEEP mode, PEEP values were chosen such that the mean airway pressure during a breath cycle was equal to that during the DEEF mode, which was higher than the conventional IPPV mode. Surgical intensive care unit of a university hospital. 20 postoperative mechanically ventilated COPD patients who were optimally pretreated and had normal blood oxygenation. Measurements were started in the IPPV (IPPV1) mode, continued in a randomized order with DEEF or PEEP, and completed with a second IPPV (IPPV2) mode, with 1 h equilibration time in each mode before each measurement. A multi-breath indicator gas wash-out test was used to calculate the EEV and ventilation inhomogeneity. There was a 9% increase (p |
