简介:摘要通过运行厌氧氨氧化反应器,我们发现无机碳源对厌氧氨氧化的反应有很大的影响,无机碳源投加量的改变对厌氧氨氧化影响不同,当无机碳源投加量小于1g/L时,对厌氧氨氧化中氨氮的影响大于亚硝态氮,当无机碳源投加量大于1g/L时,则相反。厌氧氨氧化中氨氮的抗冲击力,明显小于亚硝态氮。
简介:压疮是由于身体局部组织长时间受压,血液循环障碍,以致局部持续缺血、缺氧、营养不良而致的软组织溃烂和坏死[1].压疮是神经内科、肿瘤科和骨科常见的并发症,多见于心脑血管疾病、晚期肿瘤、脊柱损伤以及其他慢性疾病病人.据统计,在美国39%的脊髓损伤病人伴有不同程度的压疮[2].随着医疗技术的进步,这些病人的生存时间显著延长,但病人需更长时间卧床的事实也显得尤为突出,因此压疮的护理与治疗就更为重要.临床上治疗压疮的方法众多,而局部给氧治疗则是常用的联合治疗手段之一.但临床实际应用中氧浓度、操作方法各异.为了探讨压疮局部氧疗的效果与最佳氧流量,达到提高疗效、缩短治疗时间、降低医疗成本的目的,我科对不同氧浓度局部氧疗的效果进行了比较研究.
简介:摘要目的探讨牙周病患者高压氧治疗时的护理措施。方法对60例患者采用牙周病的常规护理和高压氧治疗时的专科护理及特有心理疏导。结果所有患者高压氧治疗时未出现治疗及护理并发症,疗效显著。结论良好的护理措施是保证牙周病患者顺利、规则、足疗程地进行高压氧治疗的关键。
