Which of the following parameters of mechanical ventilation is affected negatively by the use of heliox?

Question

Quizplus · Accepted Answer

The primary obstacle to heliox delivery via a mechanical ventilator is error in volume and flow measurement. Many mechanical ventilators rely on gas density to measure flows and volumes. Most errors result from underestimation of flow due to the low-density characteristics of helium. Volume is typically a mathematical integration of flow and time; therefore, volumes will be equally affected.
