How to Measure Gas Flow in a Mechanical Ventilator Using a ...

· In this article, we’ll look at another interesting application of pressure sensing in mechanical ventilation—that is, measuring gas flow using a differential pressure sensor. We will first look at two basic concepts from fluid mechanics: Bernoulli’s equation and the continuity equation. Then, combining these two concepts, we’ll derive an equation that relates the volumetric flow rate ...
