However, mechanical ventilation could not only improve respiratory function, but have a direct impact on hemodynamics by changing the intrathoracic pressure and lung volume.

然而，机械通气不仅能够改善呼吸功能，而且通过胸腔内压力及肺容积的改变，直接影响患者血流动力学。

Conclusion Inspiratory muscle training before CABG can improve respiratory function, decrease postsurgical pulmonary complications and shorten the time of mechanical ventilation.

结论CABG术前吸气肌锻炼能明显改善患者术前肺功能，缩短术后机械呼吸支持时间，减少术后肺部并发症的发生。

Which is why, during the trials, a group of doctors led by Robert Grossman of the Methodist Hospital, Houston, will monitor such things as the participants' bone density, respiratory function and cardiovascular systems, all of which are expected to improve when someone is no longer stuck in a wheelchair.
