Ambulatory Negative Pressure Sensor

In ambulatory room monitoring, the primary sensing instrument is a low- ranged differential pressure sensor. In these applications, the ventilation system is focused on creating a negative pressure environment by taking the air breathed out from the mouth of a patient and porting it through a system filter that scrubs the air and then releases it back into the cabin. The exchanging efficiency must be high to minimize the influence of first responders moving within the cabin. The sensor accuracy, high resolution, and low noise is necessary in these applications.
