Mechanical Ventilation

Respiratory support devices are designed to deliver mechanical ventilation to patients with breathing difficulties, lung diseases, or other respiratory conditions. These devices, such as oxygen concentrators, CPAP and ventilators assist in delivering oxygen, removing mucus, or supporting breathing functions.

​A continuous positive air pressure (CPAP) device prescribed by a doctor can alleviate OSA (Obstructive Sleep Apnea) conditions. A CPAP device prevents airway obstructions during sleep by forcing air into the lungs to keep the air passage open. This device helps maintain positive air pressure in order to prevent a patient’s tongue or soft palate from blocking air flow into the back of the throat. High-end CPAP devices utilize pressure sensors to control the prescribed pressure settings that are generated by the blower. Snoring detection is an additional advantage of integrating a pressure sensor.​

How we add value

​A high-pressure setting will open the airway but may cause discomfort as it impedes exhalation. Since many people snore before experiencing apnea, a pressure sensor that is able to detect snoring can be used to precisely identify the snoring trigger point and define the pressure settings, thereby reducing discomfort during exhalation.​​

Currently, most gauge pressure sensors used in CPAP equipment are digital, and thus have a predefined update rate that is often not fast enough to capture snoring events. Mitsumi’s MMR920 offers selectable SPI or I2C digital outputs, has an update rate of 0.4ms, and has been proven to capture snoring events. Additionally, the sensor includes a data ready signal for the I2C bus to optimize microcontroller communication. Our MMR920 is an ideal pressure sensor for CPAP applications.​
