why flow sensors in front of ventilator machine

Flow Sensors for mechanical ventilation

Every consumable is vital Since 1983, the proximal flow sensor has been the centerpiece of all Hamilton Medical ventilators. It provides you with valuable data from the airway opening, and the whole ventilation process depends on these measurements and their accuracy.

Ventilators and COVID-19: What You Need to Know > News ...

Jun 02, 2020· The COVID-19 pandemic has cast a spotlight on ventilators—but few know much about what they do or how they work.. A ventilator pumps air—usually with extra oxygen—into patients' airways when they are unable to breathe adequately on their own. If lung function has been severely impaired—due to injury or an illness such as COVID-19 —patients may need a ventilator.

Pressure Measuring - MIT Emergency Ventilator

Apr 22, 2020· The pressure sensor, described in Electrical Hardware and Controls, is to be connected in a position so as to allow sensing of pressure in the patient’s airway, as shown in Plumbing. Because pressure transducers with the correct specifications to sense human respiration are in low supply, these sensors should not be single-use.
