Effects of Different Mechanical Ventilation Parameters on Intra-Abdominal Pressure in COPD Patients / 天津医药

ABSTRACT

Objective To discuss the effect of different mechanical ventilation parameters on intra-abdominal pres-sure. Methods A total of 42 cases with mechanical ventilation suffering from chronic obstructive pulmonary diseases (COPD) and respiratory failure were selected for observing the effects of inspiratory platform time (Tplat), inspiratory time (Ti) and end-expiratory pressure (PEEP) on intra-abdominal pressure. Results In SIMV+PSV ventilation mode, changes of Tplat and Ti had no significant effects on intra-abdominal pressure (P>0.05). There were no significant differences be-tween SIMV+PEEP0 and base line values (P>0.05). Conclusion The alteration of peep has a great influence in intra-ab-dominal pressure, which suggests the importance of selecting proper mechanical ventilation parameters.
