Since the most significant difference happened between the middle phase of expiration and the middle phase of inspiration, this result implies that it is the intrapulmonary pressure and the cardiac volume, but not the relative position of the heart and electrodes, which cause the variation of the amplitude of QRS complex.

其中QRS波的振幅在呼气中期最高在吸气中期最低,根据呼吸运动时肺容积及肺内压变化的规律,认为是由于胸腔压力和心室舒容积的改变,而不是心脏与电极间的相对位置的改变造成了QRS波振幅的变化。

To try to limit such complications, David Pilcher, MD, a senior intensive care unit physician at Alfred Hospital in Melbourne, Australia, and colleagues developed a treatment guideline to direct care in the first 72 hours after transplant. On a simple 2-sided sheet of paper, designed to be hung at the bedside and practical enough to be useful to nurses and junior physicians, the algorithm includes direction on hemodynamic care on 1 side and respiratory care on the other.

May 3, 2007-过去的回溯性研究已经证实,接受移植病患其中央静脉压力高或是PaO2/FiO2(动脉氧气分压/吸气氧气浓度)低,在手术后,相较于没有些症状的病患,仍然需要呼吸器辅助、或是早期死亡风险较高根据项发表于国际心脏与肺脏移植学会第27届年会与科学座谈的研究,现在,研究者已经发现在手术后加护时使用一标准治疗流程,可以缩短病患仍然需要呼吸器的时间、且降低发生重移植器官功能不全的机率。

Penfield and Roberts show a region in which stimulation would occasionally cause the patient to vocalize, namely, either margin of the left Rolandic fissure. The sounds are described as a vowel, and the vocalization will last for the duration of the stimulation; if the patient runs out of breath, he will quickly inhale and continue. The patient is usually aware that he is making sounds, but he is unable to bring this under voluntary control.

潘菲尔和罗勃兹指出能让病患间歇发声的区域,就在中央沟(或称罗兰度氏裂 Rolandic fissure)右侧或左测的边缘,而刺激发出的声音是我们所称的母音,刺激的期间都能持续发声,若病患氧气不足时,他会赶紧吸气再继续发声,病患通常会意识到自己在发出声音,但是他无法随意控制自己的发声。

At a certain point in the suction cycle after the vacuum inlet, a defined amount of fresh air is let into the pump through the second suction opening from the atmosphere, thus allowing the pump not only to produce a good vacuum, but simultaneously produce a very high blast air flow even after the vacuum has been generated.

复合泵额外配有一个被称为&二次吸收&的风口。在真空进程之后的吸气循环一个特定点上,确定数量的新气体通过二次吸收口从大气进入泵体,从而使泵不仅产生良好的真空,而且在真空形成的同时产生压力很高的吹送气流。

The experimental studies were performed in the laboratory of Thermo King. Based on refrigerant flow distribution between the two evaporators, a new control method of on/off ratio of air-condition was put forward and compared with evaporator pressure regulator valves control method.

在深圳大冷王冷藏车实验室进行了制冷系统的实验研究,针对两侧蒸发器流量分配以及压缩机吸气压力波动的问题,提出了一种控制空调开停时间比的新控制方法,并与传统的蒸发压力调节阀控制方法进行了比较。

The results show that boundary layer suction can restrain the corner separated flow, weaken the intensity and scale of passage vortex, and improve the cascade flow capacity.

结果表明,采用吸力面两端吸气对抑制角区分离流动、减弱通道涡强度和尺度、提高叶栅内流动性能的效果要优于其它两种方式,积聚在角区的低能流体由于较大的吸气量而被大量吸除是性能改善的关键。

Choking milk is abnormal performance, we must read the doctor's examination, to give timely and appropriate treatment, if the milk after the baby choked breathing very smooth, it would be best way to think, let him cry and then force you to watch for when to cry oxygen and expiratory movements, watch to detect any abnormalities such as a weak voice tone, breathing difficulties, severe chest concave, etc.

呛奶是异常的表现,一定要经过医生的检查,给予及时、适当的治疗,如果呛奶后孩子呼吸很顺畅,最好还是想办法、让他再用力哭一下,以观察哭时的吸氧及吐气动作,看有无任何异常(如声音变调微弱、吸气困难、严重凹胸等),如有即送医院。
