3、定时监测血气分析结果，根据病人的生命体征和血气情况， 调整供氧方式及流量。 Regularly monitor the result of blood gas analysis and adjust the way and the flow rate of oxygen offer based on the patient‘s vital signs and blood gas.

（2）运用血管活性药物，根据患者的生命体征进 行调整 Use vasoactive drugs, and adjust according to the patient's vital signs

护理问题
Nursing Problem
◇低效性呼吸型态（Ineffective
breathing pattern） 与手术及术后伤口疼痛致咳痰无力有关 operation and postoperative wound pain induced sputum weakness ◇心输出量减少(decreased cardiac output)： 与心脏疾病、体液不足有关 Associated with heart disease, insufficient body fluid
◇潜在并发症（
potential complication ） 抗凝不足或抗凝过度 Inadequate or excessive anticoagulation、
护理措施 nursing intervention
（一）低效性呼吸型态
1、加强呼吸道护理，听诊双肺呼吸音，定时拍背、雾化， 鼓励患者咳嗽、咳痰。 Strengthen respiratory care, auscultation of lung breath sound, timed back patting ,and atomization ,and encourge patients to cough and expectorate.
诊治经过
2月20日患 者病情平稳 搬回病房。 The patient was stablly moved back to the ward on December 20th
2月17日-19日在ICU治疗
病情
2月17日在全麻CPB下行主动脉瓣置换术，术毕于12：50分带气 管插管返ICU，呼吸机辅助呼吸，清醒后，查血气示正常，于 22：30分拔出气管插管改面罩供氧。血氧饱和度99--100％，患 者咳嗽咳痰力量稍差 On december 17th, the aortic valve replacement was completed under general anesthesia CPB ,and the patient returned the icu at 12:50 with ventilator breathing. After waking, her blood check showed normal, so pulled out endotracheal intubation and it was replace by oxygen masks. The oxygen saturation was respectively 99%--100％. Patients with cough and expectoration somewhat less power.
