下气道

However, because of the consuming time and result jumpiness of using CFD, CFD can't replace the steady flow test in process of the development of the engine intake port presently.

但由于CFD相对试验来说耗时长，而且各气门升程下计算数据波动较大，故目前开发优化气道流程中CFD仍不能完全替代气道稳流试验。

Their sequential midline sagittal and axial images were obtained and displayed in the cine mode. Then we examined the upper airway of the retropalate region, retroglottal region and epiglottal region. We also did dynamic fiberoptic pharyngoscopy examination during sleep in 8 patients in another night.

对经多导睡眠监测（polysomnography， PSG）确诊的15例 OSAS患者应用超快速MRI在睡眠状态下对其上气道进行了矢状位和轴位扫描动态观察，对患者软腭后区（retropalatal region ， RP）、舌后区（retroglossal region， RG）和会厌区（epiglottal region， EPG）的上气道阻塞情况进行了观察分析。

Results:Length of soft palate and distance from tip of the uvula to NS were negatively related to the retropalatal airway both in sitting and supine position.

结果：两种体位下腭后气道大小与软腭长度及悬雍垂顶点到颅底距离均呈显著负相关，两种体位下腭后气道有显著差异。

METHODS: Pulmonary function tests were performed in 20 children with asthmatoid bronchitis (2 months-2.5 years of age) before and 30, 60, and 120 minutes after salbutamo and ipratropium bromide inhalation. The indexes of pulmonary function measured included tidal breathing flow volume loop, percent of tidal volume to peak tidal expiratory flow, terminal flows per peak expiratory flow (25/PF), peak tidal expiratory flow, rate of mid-expiratory to mid-inspiratory flow, respiratory rate and tidal volume per kilogram. RESULTS: Before drug inhalation, the descending branch of the TBFV loop was depressed.

20例2个月至2岁6个月的喘息性支气管炎患儿，在吸入药物沙丁胺醇+溴化异丙托品前、吸入后30，60，120min各行一次潮气流速容量环检查，并进行肺功能各项指标比较，包括潮气呼吸流速容量环的形态，反映小气道功能的敏感指标到达潮气呼气峰流速时的呼气量/潮气量，呼出75%潮气量时的呼气流速/潮气呼气峰流速(25/PF)，潮气呼气峰流速，反映大气道功能的指标潮气呼气中期流速/潮气吸气中期流速，潮气呼吸状态下的通气功能，包括呼吸频率，每公斤体重潮气量。

However, there were a great number of inflammatory cells, epithelial proliferation, partial breakage and defluvium of the airway epithelium in the bronchus, below the vessel mucous membrane and around lung tissues in the model control group.

正常对照组小鼠气道无明显炎症改变；模型对照组小鼠支气管、血管粘膜下和周围肺组织有明显炎症细胞浸润、气道上皮增生、气道黏液增多、气道上皮部分断裂脱落；细胞移植组小鼠气道炎症明显减轻。

Practice on mannequins was associated with improved comfortin using infraglottic airways in patients.

在人体模型上练习有助于提高声门下气道通气的技能。

MethodsFrom January 2003 to June 2008, 109 (98 males and 11 females) cases of severe OSAHS were treated with UPPP. All patients were checked with a fiber optic laryngoscope of Muller and X-ray or CT for upper air flue when they were in a waking state to locate the collapse level (oropharyngeal and palatopharyngeal level, most of them had an obstruction on the oropharyngeal level). After the UPPP, they were sent to the ICU and monitored with trachea cannula for 1 to 2days.

方法对重度OSAHS患者行UPPP联合舌骨悬吊术109例，每例患者术前均行清醒状态纤维喉镜下Muller检查、上气道的X线片或上气道CT测量，术前确定阻塞平面为腭-咽及舌-咽平面，但以舌-咽平面为主，均行UPPP联合舌骨悬吊术，术后均于ICU保留气管插管监护1～2d。

Attack the state of the Organization of congestive airway, edema, cramps, so that the airway narrow and blocked, affecting normal breathing, the use of Anti-allergy symptoms, spasmolytic measures to control seizures, relieve the symptoms.

发作状态下的气道组织充血、水肿、痉挛，使气道狭窄、阻塞，影响正常呼吸，对症使用抗敏、解痉措施可控制发作，减轻症状。

We compared conventional and continuous aspiration of subglottic secretions procedures in ventilated patients after major heart surgery.

我们在重大心脏手术后通气患者中对常规和连续声门下气道分泌物抽吸操作进行比较。

It has been put forward that there exists single Ball point and double Ball points on the symmetrical connecting-rod curves of equilateral mechanisms.

从鲍尔点的形成原理出发，分析对称连杆曲线上鲍尔点的产生条件，提出等边机构的对称连杆曲线上有单鲍尔点和双鲍尔点。
