Oxygen economizing devices have been extensively studied, both at rest and during muscular exercise, in an attempt to increase the autonomy of a portable oxygen apparatus. The aim of this study is threefold: first, to suggest a simple method to verify in a simple way the technical accuracy of a demand flow oxygen delivery device; second, to suggest how we can monitor in a simple way the clinical efficacy of an economizer; and third, to remember that we can utilize an oxygen saving device to give a better protection than nasal prongs against the worsening of HbO2 desaturation induced by exercise.
为提高便携式氧气设备的自主性，人们已对氧气节约装置在静息和肌肉运动期间进行了广泛研究。本研究的目的有三个：第一，提出一种简单方法，以简便方式验证按需流量氧气输送装置的技术准确性；第二，提出如何以简单方式监测节约器的临床疗效；第三，提醒我们可以利用氧气节约装置提供比鼻导管更好的保护，以防止运动引起的血红蛋白氧饱和度恶化。
