Technical Study on Laser Processing Technology of The Autoflow Balancing Valve Spool 自动流量平衡阀阀芯的激光加工工艺研究
Methods Compare the variables of delivery tidal volume, peak airway pressure ( PAP) and mean airway pressure ( MAP) in volume controlled ventilation before and after assisted with autoflow under different pre-set flow velocity, compliance and resistance simulated on model lung. 方法观察模拟肺在不同的顺应性、阻力下,采用不同吸气流速容量控制通气辅用自动变流前后输送潮气量、气道峰压、平均压的变化。
Conclusions Volume-controlled ventilation assisted with autoflow may be helpful among the patients whose peak inspiratory pressure and mean airway pressure should be kept in a lower level, while delivery tidal volume should be assured. 结论在需要保证输送潮气量,又尽可能控制气道峰压、气道平均压时,容量控制通气辅用自动变流是一种较好的方法。
The correlated factor of PAP, MAP, peak inspiratory flow velocity ( Pflow) and mean inspiratory flow velocity ( Mflow) after being assisted with autoflow also be discussed. 并探讨辅用自动变流后气道峰压、平均压、吸气峰值流速和平均流速分别与系统阻力、顺应性的相关性。
Objective To demonstrate the changes of delivery tidal volume, peak inspiratory pressure and mean airway pressure before and after volume-controlled ventilation assisted with autoflow. 目的观察容量控制通气辅用自动变流前后输送潮气量、气道峰压、平均压的变化。
