Pressure Sensors for Mechanical Ventilators and ...

· The use of pressure sensors in ventilators and respirators is similar to their use in CPAP and BiPAP. Essentially, when the lungs need assistance taking in air, a machine blows the required amount of air into the lungs. But how does the medical professional monitor and control the required amount of air, or positive airway pressure? This is where pressure sensors play a critical role.

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 ...
