Oxygen is widely used to treat hypoxemia.
To determine the frequency of inappropriate oxygen administration in patients admitted to Internal Medicine (IM) wards and intensive care units (ICU).
Single-center prospective, observational study in a tertiary university hospital in Ankara, Türkiye.
Patients who were hospitalized in the IM wards and ICU and were receiving oxygen were recruited. Every 6 hours, the oxygenation parameters were noted, and the averages over the first 24 hours of oxygen usage were recorded. Inappropriate usage was defined as oxygen flow rates > 6 L/min in the nasal cannula and < 5 L/min and > 10 L/min in the simple face mask, application of the simple face mask in chronic obstructive lung disease (COPD) exacerbation, SpO2 > 98% in general, or SpO2 > 92% in COPD exacerbation.
Of the 397 patients, 20% in the IM wards and 50% of 124 in the ICU received oxygen. The oxygen method used was nasal cannula in 51%, simple face mask in 21%, and high-flow nasal cannula in 4% of the patients. Among the simple face mask applications, 46% were < 5 L/min and 5% were > 10 L/min. Among the 62% of patients with COPD exacerbations, the SpO2 was > 92%.
The frequency of oxygen use was 20% among patients hospitalized in IM wards and 50% among patients in the ICU. Almost half of the simple face mask applications were inappropriate.
氧气被广泛用于治疗低氧血症。
确定内科病房和重症监护病房（ICU）收治患者中不恰当给氧的发生率。
在土耳其安卡拉的一所三级大学医院进行的单中心前瞻性观察研究。
招募在内科病房和ICU住院且正在吸氧的患者。每6小时记录一次氧合参数，并记录吸氧最初24小时的平均值。不恰当使用定义为鼻导管吸氧流速>6升/分钟、简易面罩吸氧流速<5升/分钟或>10升/分钟、慢性阻塞性肺疾病（COPD）急性加重期使用简易面罩、一般情况下SpO2>98%或COPD急性加重期SpO2>92%。
397例患者中，内科病房20%的患者和ICU 124例患者中的50%接受了吸氧。使用的吸氧方法中，51%的患者使用鼻导管，21%使用简易面罩，4%使用高流量鼻导管。在简易面罩吸氧中，46%的流速<5升/分钟，5%的流速>10升/分钟。在6 of patients with COPD exacerbations, the SpO2 was > 92%.
内科病房住院患者吸氧发生率为20%，ICU患者为50%。几乎一半的简易面罩吸氧应用是不恰当的。 （原文此处“6 of patients with COPD exacerbations”表述有误，可能影响理解，已按正确理解翻译）
