Abstract:

Objective To learn about the current status of nurses’ knowledge concerning oxygen therapy,so as to provide the references for implementing training programs to promote safer oxygen therapies. Methods A self-designed questionnaire was carried out from May 4th to June 30th,2019 to investigate the mastery of knowledge concerning oxygen therapy among nurses who are the members of internal medicine nursing committee,association,critical care nursing committee,geriatric nursing committee and community nursing committee in certain nurse associations. The questionnaire is consisted of 5 parts,namely the content of the oxygen therapy from doctors’ prescription,demographic characteristics of the subjects,the indication of oxygen therapy,the assessment of oxygenation status and implementing oxygen therapy（practicing,monitoring and evaluation）. Results 2 789 nurses participated the survey,among which there were 2 719 effective and valid questionnaire,with the response rate of 97.49%. 87.75% of nurses are aware that the oxygen therapy should be undertaken based on the prescription. Only 18.50% of nurses insist that the target saturation should be included in the prescription. 82.42% of nurses mistakenly believe that the oxygen therapy could treat the underlying diseases which lead to the hypoxaemia. Over 95.29% of nurses believe that breathlessness could be relieved by oxygen therapy,while this is a common mistake. 3.49% of nurses could indicate the correct saturation range of the needed continuous monitoring. Except for chronic obstructive lung disease,the correct answer rates of nurses to several diseases risking of hypercapnia are less than 70.00%. 22.25% of nurses could indicate the correct target saturation for the patients with the risk of hypercapnia. Only 16.77% of nurses could indicate the correct time period of monitoring saturation once the oxygen therapy is paused. Conclusion Based on the results from the survey,the knowledge mastery of nurses on oxygen therapy needs to be improved. In order to correct the misunderstandings in oxygen therapy cognition and to provide more accurate and safer oxygen practice for the patients,the systematic training for the nurses should be developed and implemented.

摘要：

目的 了解临床护士对氧疗安全的认知情况,为制订相关培训方案提供参考。 方法 采用便利抽样法,于2019年5月4日—6月30日采用自行编制的问卷对来自30个省市200所医院的2 789名护士进行调查,调查内容包括氧疗医嘱内容及实施人员、氧疗目的和适应证、氧疗评估、氧疗实施等。 结果 共收回问卷2 789份,其中有效问卷2 719份,有效问卷回收率为97.49%。87.75%的护士认识到应根据医嘱实施氧疗,但只有18.50%的护士认为氧疗医嘱应包括目标血氧饱和度;82.42%的护士误认为氧疗可以治疗患者的原发病;95.29%的护士误认为氧疗可以缓解患者呼吸困难的症状;仅3.49%的护士知晓当患者血氧饱和度下降3%时需要连续监测血氧饱和度;除COPD患者外,护士对其他具有高碳酸血症风险的患者知晓率均小于70.00%;仅22.25%的护士能正确指出高碳酸血症风险患者氧疗时的目标血氧饱和度;仅16.77%的护士能正确回答氧疗停止1 h后监测患者血氧饱和度的时间。 结论 临床护士在氧疗安全方面的认知有待提高。应开展系统培训,纠正护士在氧疗认知上的误区,以进一步规范氧疗实践,为患者提供更为安全、精准的氧疗。
