Every year, pneumonia kills more children before their fifth birthday than does any other infectious disease. To end preventable deaths of neonates and children younger than 5 years by 2030 (UN Sustainable Development Goal 3.2), effective primary care interventions for child pneumonia are needed. Hypoxaemia, low blood oxygen, is a key risk factor for child pneumonia mortality. In high-income settings, pulse oximeters, non-invasive portable devices that measure the peripheral arterial oxyhaemoglobin saturation (SpO ₂), have been used in routine paediatric clinical practice for more than 30 years. By contrast, most paediatric primary care settings in low-income and middle-income countries (LMICs) do not routinely use pulse oximeters at all.

低收入和中等收入国家的儿科初级保健中的脉搏血氧饱和度测定法。

每年，与其他传染病相比，肺炎在五岁生日之前杀死的儿童人数更多。为了在2030年前结束新生儿和5岁以下儿童的可预防死亡（联合国可持续发展目标3.2），需要有效的儿童肺炎初级保健干预措施。低氧血症，低血氧是儿童肺炎死亡的关键危险因素。在高收入环境中，用于测量外周动脉血红蛋白血红蛋白饱和度（SpO ₂）的无创便携式脉搏血氧仪已在常规儿科临床实践中使用了30多年。相比之下，低收入和中等收入国家（LMIC）的大多数儿科基层医疗机构根本没有常规使用脉搏血氧仪。
