With the high frequency of acute respiratory infections in children worldwide, particularly so in low-resource countries, the development of effective diagnostic support is crucial. While pulse oximetry has been found to be an acceptable method of hypoxemia detection, improving clinical decision making and efficient referral, many healthcare set ups in low- and middle-income countries have not been able to implement pulse oximetry into their practice.
A review of past pulse oximetry implementation attempts in low- and middle-income countries proposes the barriers and potential solutions for complete integration in the healthcare systems. The addition of pulse oximetry into WHO health guidelines would prove to improve detection of respiratory distress and ensuing therapeutic measures. Incorporation is limited by the cost and unavailability of pulse oximeters, and subsequent oxygen accessibility. This restriction is compounded by the lack of trained personnel, and healthcare provider misconceptions. These hurdles can be combated by focus on low-cost devices, and cooperation at national levels for development in healthcare infrastructure, resource transport, and oxygen delivery systems.
The implementation of pulse oximetry shows promise to improve child morbidity and mortality from pneumonia in low- and middle-income countries. Steady measures taken to improve access to pulse oximeters and oxygen supplies, along with enhanced medical provider training are encouraging steps to thorough pulse oximetry integration.
鉴于全球儿童急性呼吸道感染的高发频率,尤其是在资源匮乏的国家,开发有效的诊断支持至关重要。虽然脉搏血氧饱和度测定法已被证明是一种可接受的低氧血症检测方法,有助于改善临床决策和高效转诊,但许多低收入和中等收入国家的医疗机构仍无法将脉搏血氧饱和度测定法纳入其实际操作中。
对低收入和中等收入国家过去实施脉搏血氧饱和度测定法的尝试进行的一项综述提出了在医疗系统中完全整合的障碍及潜在解决方案。将脉搏血氧饱和度测定法纳入世界卫生组织的健康指南将有助于改善对呼吸窘迫的检测及后续治疗措施。其应用受到脉搏血氧仪成本高、难以获取以及后续氧气供应的限制。缺乏训练有素的人员以及医疗服务提供者的误解使这一限制更加复杂。可以通过关注低成本设备以及在国家层面开展合作以发展医疗基础设施、资源运输和氧气输送系统来克服这些障碍。
实施脉搏血氧饱和度测定法有望降低低收入和中等收入国家儿童因肺炎导致的发病率和死亡率。采取稳定措施改善脉搏血氧仪和氧气供应的可及性,以及加强医疗服务提供者培训,是全面整合脉搏血氧饱和度测定法的积极步骤。
