What specific function do built-in oxygen analyzers serve in specialized Heliox delivery systems?
Answer
To immediately verify the fraction of inspired oxygen ($ ext{FiO}_2$)
Dedicated Heliox blending equipment, such as the Vapotherm Precision Flow® Heliox system, is designed to integrate the helium and oxygen sources to deliver a precise, continuous blend. A critical safety and accuracy feature incorporated into these advanced systems is the presence of built-in oxygen analyzers. Since the oxygen component is the element that sustains life, these analyzers function to immediately verify the fraction of inspired oxygen ($ ext{FiO}_2$) being delivered. This constant monitoring ensures that the desired blend ratio is maintained and that the life-sustaining oxygen concentration remains accurate, compensating for potential mixing errors.
