To evaluate both concordance among those measurements obtained by three different pulse oximeters currently used by nursing professionals in hospital units and the factors which can influence this concordance.
Many models of wireless pulse oximeters in the present market do not offer possibility of calibration and, therefore, they do not ensure patients' safety in daily clinical practice.
This is a descriptive and cross-sectional study. The sample of patients (140) was selected from such hospital units, and all of them had to fulfil inclusion and exclusion criteria for participation.
The instruments used to carry out this research were a monitor (calibrated), two models of portable wireless pulse oximeters (used for 3 years by the nursing staff, without being calibrated), a tympanic thermometer and a weather meter. The concordance correlation coefficient (CCC) was used to establish the concordance, whereas the Landis-Koch criteria were used to interpret the results.
The concordance among the three devices was considered as "good" (CCC: 0.925 and 0.974 (95%)). The CCC (0.925) for saturation measures was regarded as "very good"/"almost perfect," and the pulse measure was considered as "very good" CCC 0.974, providing in both cases a high level of concordance (CCC > 0.91).
The overall concordance as regards pulse and oxygen saturation among the three pulse oximeters analysed is considered as "very good" according to the Landis-Koch criteria.
There exists a "very good" concordance among two wireless oximeters which have been used by the health staff for 3 years and which did not offer any possibility of calibration and one monitor which belongs to the healthcare institution. This aspect is of crucial importance in daily clinical practice, and it is also relevant to ensure patient's safety.
评估目前医院各科室护理人员使用的 3 种不同脉搏血氧计测量值的一致性，以及影响这种一致性的因素。
目前市场上许多无线脉搏血氧计型号都没有校准功能，因此不能确保患者在日常临床实践中的安全。
这是一项描述性和横断面研究。从这些医院科室中选择了（140）名患者作为样本，所有患者都必须符合参与的纳入和排除标准。
本研究使用的仪器包括一个（经校准的）监护仪、两种（已被护理人员使用了 3 年但未进行校准的）便携式无线脉搏血氧计、一个鼓膜温度计和一个气象计。使用一致性相关系数（CCC）来确定一致性，使用 Landis-Koch 标准来解释结果。
这三种设备之间的一致性被认为是“好”（CCC：0.925 和 0.974（95%））。饱和度测量的 CCC 被认为是“非常好”/“几乎完美”，脉搏测量的 CCC 被认为是“非常好”，值为 0.974，在这两种情况下都提供了高度的一致性（CCC>0.91）。
根据 Landis-Koch 标准，分析的 3 种脉搏血氧计中，脉搏和氧饱和度的总体一致性被认为是“非常好”。
在日常临床实践中，医护人员使用了 3 年且没有校准功能的两种无线血氧计与属于医疗机构的一个监护仪之间存在“非常好”的一致性。这一点在临床实践中非常重要，也与确保患者安全有关。
