Sensors in Ventilation Devices

Learn how different sensor technologies are used in invasive and non-invasive ventilation equipment.

Life saving breathing aid

Mechanical ventilators are life saving devices for patients who are unable to breathe unassisted or need additional oxygen intake. Ventilation devices are found everywhere from intensive care units to home portable units. Ventilators pump breathable air or a mixture of air and gases into and out of the lungs either via an artificial airway (invasive ventilation) or via a face mask (non-invasive ventilation). For patients that can breathe unassisted but have a low level of blood oxygen, an oxygen concentrator provides a beneficial oxygen boost. Concentrators accomplish this by lowering the nitrogen content of the air. Oxygen conservers supply oxygen enriched air to the patient fed by an oxygen tank.

Supporting Sensing Technologies

TE Connectivity’s (TE) sensor technology allows for highly reliable and accurate measurements for these life critical applications. Low pressure sensors are utilized to control the airflow to the patient as well as the exhalation process and monitor the filter cleanliness. Sensors with high pressure ranges monitor the oxygen tank and air supply pressure. Additionally an absolute sensor can be integrated for barometric compensation to correct for altitude measurement errors. TE’s comprehensive pressure portfolio covers ultra-low to high pressure ranges, media compatible and stainless steal solutions, analog and digital interfaces, and products that are cleaned for oxygen service. For increased patient comfort, a humidifier adds heat and moisture to the inflow air. To support this function, TE offers humidity and temperature sensors. Besides the core functions TE's offering includes CO2 sensors and sensors for motor and fan control.
