除吸气抑制反射外，肺充气通过迷走神经对呼吸中枢可能产生了另一种作用，其作用效果主要体现在呼吸周期的改变上。
Except for inspiration inhibition reflex, lung inflation might have another effect on respiratory center var vagus. It is mainly represented by the change of respiratory period.
睡眠质量是关键。睡眠呼吸终止症——睡觉时由于呼吸的暂停而周期性苏醒的现象——与心血管病有很大关联。
However, quality of sleep is key. Sleep apnea-a condition in which you wake up periodically due to interrupted breathing-has been linked with cardiovascular disease.

In addition, specific sleep disorders such as sleep apnea and periodic limb movement disorder are also associated with age, and affect sleep.
首先，中枢神经必须赋予呼吸肌的周期性收缩和放松一种节奏。
First, the CNS must produce a rhythm for the periodic cycle of contraction and relaxation of respiratory muscles.

Result The treatment group showed quicker remission of acute respiratory failure and shorter time to get consciousness and less hospitalization period, no patient died and no sequela.
