Abstract

Background: Chronic respiratory diseases represent a significant global health burden, affecting millions of individuals. Long-term oxygen therapy (LTOT) has been a key treatment for patients with chronic hypoxemia due to these conditions, demonstrating benefits for survival and quality of life.

Methods: An observational, analytical, retrospective cohort study was conducted to evaluate clinical indicators for safely discontinuing oxygen therapy in 36 patients aged 50 years or older with chronic respiratory diseases residing in five nursing homes. Data included sociodemographic and clinical variables, such as comorbidities, oxygen saturation levels, and treatment details. A cohort of 36 nursing home residents with chronic respiratory diseases was analyzed.

Results: The study revealed that 83.3% of patients had at least one comorbidity. Most patients (80.6%) used a nasal cannula for oxygen delivery, with a mean flow rate of 2.06 L/min. Approximately 80.6% achieved oxygen saturation >92% without supplemental oxygen. None of the patients who discontinued oxygen required readmission or oxygen reinstatement within the 4-week follow-up period.

Conclusions: This study provides preliminary evidence that achieving oxygen saturation >92% at rest or in exertion may represent a potential clinical indicator for safely discontinuing supplemental oxygen in patients with chronic respiratory diseases. However, given the retrospective design and small sample size, these findings should be interpreted cautiously and validated in larger, prospective studies.

实施基于氧饱和度的标准对慢性呼吸系统疾病养老院居民停止长期氧疗。

背景：慢性呼吸道疾病是一项重大的全球健康负担，影响着数百万人。长期氧疗（LTOT）一直是慢性低氧血症患者的关键治疗方法，证明了对生存和生活质量的益处。方法：采用观察性、分析性、回顾性队列研究，对5家养老院36例50岁及以上慢性呼吸系统疾病患者安全停氧的临床指标进行评价。数据包括社会人口学和临床变量，如合并症、血氧饱和度水平和治疗细节。对36名患有慢性呼吸系统疾病的养老院居民进行队列分析。结果：83.3%的患者至少有一种合并症。大多数患者（80.6%）使用鼻插管供氧，平均流量为2.06 L/min。大约80.6%的人在没有补充氧气的情况下达到了氧饱和度。在4周的随访期内，无一例停止供氧的患者需要再次入院或恢复供氧。结论：本研究提供了初步证据，表明在休息或运动时达到血氧饱和度>92%可能是慢性呼吸系统疾病患者安全停止补充氧气的潜在临床指标。然而，考虑到回顾性设计和小样本量，这些发现应该谨慎解释，并在更大的前瞻性研究中得到验证。
