慢性阻塞性肺疾病患者血氧变化特点及护理

目的　探讨慢性阻塞性肺疾病 (COPD)患者血氧变化特点及护理。方法　观察 5 0例COPD患者 2 4h动态SaO2 及心电图变化情况。结果　 5 0例患者夜间SaO2 均下降 ,其中 35例SaO2 下降幅度大于 10 % ,凌晨 1:0 0 3:0 0SaO2 最低 ;夜间房性早搏较白天明显增高 ,经t检验 ,t=10 .7,P <0 .0 1,具有显著性差异。结论　根据COPD患者夜间SaO2 明显下降的特点 ,加强夜间呼吸道管理 ,防止SaO2 下降 ,是提高COPD患者生存质量 ,降低死亡率的关键。

The changes of SaO_2 in patients with chronic obstructive pulmonary disease and the nursing strategy

ObjectiveTo investigate the characteristics of changes of oxygen saturation of blood (SaO 2) changes in patients with chronic obstructive pulmonary disease (COPD) and discuss the nursing strategy.MethodsSaO 2 and dynamic ECG were monitored in 50 patients with COPD.ResultsA decline of SaO 2 was observed at night in all of the 50 cases. The level of nocturnal SaO 2 decreased more than 10% in 35 cases. The lowest level of SaO 2 appeared at 1:00~3:00 a.m. The occurrence of atrial and/or ventricular premature beats increased significantly at night.ConclusionIn view of the significant decline of nocturnal SaO 2, the key in nursing exists in strengthening observation of the respiratory tract and prevention of decline of nocturnal SaO 2 in order to improve the life quality and decrease the mortality of patients with COPD.
