延长吸氧管对氧疗效果的影响

目的探讨适当延长吸氧管长度对血氧饱和度的影响。方法对持续低流量氧疗病人按应用2 m、3 m、4 m、5 m吸氧管吸氧分为4组,观察血氧饱和度,计算氧气充满吸氧管时间,并调查延长吸氧管吸氧病人满意度。结果 4组病人组内比较吸氧后5 min和吸氧后10 min,末梢血氧饱和度均高于吸氧前(P<0.01);组间比较吸氧前、吸氧后5 min和吸氧后10 min,末梢血氧饱和度差异无统计学意义(P>0.05)。2 m、3 m、4 m、5 m吸氧管氧气充满管腔时间为1.26 min、1.88 min、2.51 min、3.14 min。病人均乐于接受延长吸氧管吸氧。结论适当延长吸氧管长度对吸氧效果无不良影响,既满足了氧疗病人用氧需求,又利于病人床边活动,利于疾病的康复。

Study on effects of prolonged oxygen inhalation tube on oxygen therapy/

Objective To explore the effects of prolonged oxygen inhalation tube on oxygen therapy. Methods Patients with persistent low flow oxygen therapy were treated with 2 m,3 m,4 m and 5 m oxygen inhalation tube for oxygen therapy respectively. The blood oxygen saturation, the time of oxygen inhalation tube filling with oxygen and the patient satisfaction with prolonged oxygen inhalation tube were compared among the four groups. Results The peripheral oxyen staturation in 5 and 10 minutes after oxygen therapy were higher than those before oxygen therapy within 4 groups comparisons （ P 〈 0.01 ）. There were no signifi- cant differences among the four groups in the peripheral oxygen saturation before oxygen therapy 5 and 10 minutes after oxygen therapy （P 〉 0.05 ）. And the time of 2 m ,3 m ,4 m and 5 m oxygen tube filling with oxygen were 1.26 rain, 1. gg rain ,2.51 min and 3.14 min, respectively. All the patients applauded for the pro- longed oxygen inhalation tube. Conclusion The appropriately prolonged oxygen inhalation tube has no adverse effects on oxygen therapy. And it not only meets the demands of oxygen therapy for patients, but also benefits for the bedside activities of patients and the rehabilitation of disease.
