Pulse oximetry is widely used to measure oxygen saturation in inpatient and outpatient settings. As with any medical technology, competence in interpretation and application of the data is essential for patient care. We therefore undertook a study to quantify pediatric house staff's knowledge of pulse oximetry and their ability to interpret the information.
A 16-item multiple choice questionnaire (6 demographic, 10 knowledge) was developed to assess knowledge of pulse oximetry. The questionnaire was administered to a total of 134 pediatric house staff from five medical school-affiliated residency programs in New York City.
The mean test score and standard deviation was 64.3% +/- 1.9, with a range of 10% to 100%. Regarding three questions related to the knowledge of the oxyhemoglobin deviation curve, only 17% of the the respondents answered all three questions correctly. In three questions pertaining to the accuracy of the pulse oximeter, 36% of the respondents answered all questions correctly. Forty-three percent of the house staff believed that training in the use of pulse oximetry was inadequate.
The results showed that there is marked variability in pediatric house staff's knowledge of all aspects of pulse oximetry. This could contribute to patient morbidity. We suggest that medical schools and residency programs place more emphasis on teaching the principles and applications of pulse oximetry and the oxyhemoglobin dissociation curve.
脉搏血氧饱和度测定法广泛应用于住院和门诊环境中测量血氧饱和度。与任何医疗技术一样，对数据的解读和应用能力对于患者护理至关重要。因此，我们开展了一项研究，以量化儿科住院医师对脉搏血氧饱和度测定法的知识以及他们解读信息的能力。
编制了一份包含16个项目的多项选择题问卷（6项人口统计学问题，10项知识问题），以评估对脉搏血氧饱和度测定法的知识。该问卷共发放给来自纽约市五所医学院附属住院医师培训项目的134名儿科住院医师。
平均测试成绩和标准差为64.3%±1.9%，范围为10%至100%。关于与氧合血红蛋白偏差曲线知识相关的三个问题，只有17%的受访者全部回答正确。在与脉搏血氧仪准确性相关的三个问题中，36%的受访者全部回答正确。43%的住院医师认为脉搏血氧饱和度测定法的使用培训不足。
结果表明，儿科住院医师对脉搏血氧饱和度测定法各方面的知识存在显著差异。这可能导致患者发病。我们建议医学院和住院医师培训项目更加重视讲授脉搏血氧饱和度测定法及氧合血红蛋白解离曲线的原理和应用。
