目的：探讨侧卧位单肺容量控制通气时，吸呼比1∶1对老年患者呼吸动力学及氧合的影响。方法：选择56例老年开胸患者分成两组，实施容量控制单肺通气吸呼比为1∶1（A组）和1∶2（B组），分别在双肺通气后15 min，单肺通气后30 min及60 min，恢复双肺通气后15 min，记录动静脉血气分析结果和呼吸参数。结果：与B组相比，单肺通气期间A组的气道峰压和气道平台压（cm H2O）的标准差明显偏低（P<0.01）；动脉-呼气末二氧化碳分压差明显偏低（P<0.01）；而单肺通气期间的动脉氧分压PaO2无明显差异。结论：侧卧位单肺容量控制通气时1∶1吸呼比与1∶2相比能降低气道峰压和气道平台压，改善动态顺应性和肺泡通气效率，但不能实质改善动脉氧合。
目的：探討側臥位單肺容量控製通氣時，吸呼比1∶1對老年患者呼吸動力學及氧閤的影響。方法：選擇56例老年開胸患者分成兩組，實施容量控製單肺通氣吸呼比為1∶1（A組）和1∶2（B組），分彆在雙肺通氣後15 min，單肺通氣後30 min及60 min，恢複雙肺通氣後15 min，記錄動靜脈血氣分析結果和呼吸參數。結果：與B組相比，單肺通氣期間A組的氣道峰壓和氣道平檯壓（cm H2O）的標準差明顯偏低（P<0.01）；動脈-呼氣末二氧化碳分壓差明顯偏低（P<0.01）；而單肺通氣期間的動脈氧分壓PaO2無明顯差異。結論：側臥位單肺容量控製通氣時1∶1吸呼比與1∶2相比能降低氣道峰壓和氣道平檯壓，改善動態順應性和肺泡通氣效率，但不能實質改善動脈氧閤。

Objective: To investigate the lateral position of single lung ventilation volume control ventilation, call absorption ratio 1∶1 on elderly patients with respiratory dynamics and the influence of oxygen. Method: To choose 56 patients with elderly thoracotomy, randomly divide into 2 groups, the implementation of volume control ventilation, single lung ventilation call absorption ratio of 1∶1 (group A) respectively and 1∶2 (group B). After the double lung ventilation one-lung ventilation after 15 minutes, 30 minutes and 60 minutes, 15 minutes after the double lung ventilation recovery record arteriovenous blood gas to respectively analyze results and respiratory parameters.Result:Compared with group B, group A during the period of single lung ventilation airway peak pressure and airway platform (cm H2O) standard deviation was significantly lower (P<0.01). Artery-breathe out CO2 partial pressure difference at the end was lower significantly (P<0.01). The arterial oxygen partial pressure during one-lung ventilation PaO2 had no obvious difference.Conclusion:Lateral position of single lung volume control ventilation, compared with the 1∶2, 1∶1 call absorption than lower airway peak pressure and airway platform, improve the dynamic compliance and alveolar ventilation efficiency, but not the essence and improve arterial oxygen.
