通气

Indeed, by increasing the pressure in the right atrium and in the left ventricle with respect to extrathoracic vascular beds, positive-pressure ventilation affects the pressure gradients for both systemic venous return and left-ventricular ejection increase; Fig.

实际上，机械正压通气引起的右心房、左心室内的压力增加，这样和胸腔外血管床形成一定的压力梯度，此压力梯度会影响心肺两系统的静脉回流及左心射血（增加，见图1）。

OBJECTIVE: A systematic review of weaning and extubation for pediatric patients on mechanical ventilation.

目的：对儿科机械通气患者的脱机和拔管进行系统回顾。

Arcuata; A large quantity of cells in fascicular nodules were infected by rhizobia; 16S rRNA gene sequence of T. arcuata shared the highest identities with that of Sinorhizobium meliloti, and this strain was able to tolerate relatively higher temperature and alkalin.

弯果胡卢巴结瘤需要较好的土壤及通气条件；根瘤簇生，瘤内含大量被根瘤菌侵染的细胞；弯果胡卢巴根瘤菌与苜蓿中华根瘤菌同源性最高，是一类较耐高温和强碱的菌株。

Experiments have been made to investigate the performance of pump operating under conditions of air-water, solid-water and air-water-solid, also considered influence of adding frother when entrained air.

通过大量的试验，进行了气液、固液、气液固等各工况下泵性能的研究，并考虑了通气时加入起泡剂的影响。

The jaw advancement by ramus osteotomy and genioplasty for treating micromandibular deformity associated with OSAS can correct the maxillofacial deformities and enlarge the upper airway space to relieve OSAS. This method has achieved satisfactory result.

结论下颌升支截骨下颌骨前徙术治疗小下颌畸形伴OSAS，对扩张口咽通气道、解除睡眠时呼吸阻塞症状可获得较满意的效果，并同时改善了面部容貌。

If the partial pressure of oxygen decreases by 5% or more or by 4 mm Hg [0.5 kPa] or more when the patient moves from a supine to an upright position, or if the patient has worsening dyspnea related to further ventilation perfusion mismatch, then hepatopulmonary syndrome may be the problem.

如果当病人从仰卧位变为直立位时氧分压降低大于等于5%，或者降低大于等于4 mm Hg （0.5 kPa）--直立性低氧血症--或者病人由于通气灌注障碍导致呼吸变得更加困难，都可能是肝肺综合征造成的问题。

Objective To study the clinical parameters in obstructive sleep apnea/hyperpnoea syndrome.

目的 结合临床资料探讨阻塞性睡眠呼吸暂停低通气综合征的临床相关因素。

Methods: The postoperative complications of 31 patients with moderate pulmonary hypofunction and 62 patients with normal pulmonary function were reviewed.

本研究探讨了肺通气功能中度减退的肺癌患者术后并发症发生情况，探讨与并发症发生的其他相关因素。

METHODS: After induction of general anesthesia (1 minimum alveolar anesthetic concentration halothane and laryngeal mask airway), 62 children scheduled for inguinal surgery received an ilioinguinal/iliohypogastric nerve block based on standard anatomical landmarks.

全麻诱导后（1MAC 氟烷和喉罩通气），对62个择期行腹股沟手术的儿童在标准解剖定位下做髂腹下/髂腹股沟神经阻滞。

She gently rebuff ed him, but agreed that they could be friends

她婉言拒绝了，但同意作为朋友相处。

If in the penal farm, you were sure to be criticized.
