Patients receiving a range of medical therapies in healthcare settings frequently require the provision of an oxygen-rich air mixture (pure medical-grade oxygen mixed with filtered and humidified ambient air or PSA-generated oxygen).
Doctors and medical personnel are frequently required to accurately monitor and control air volume, gas concentration, rate of flow or pressure in real-time. This varies depending on the situation or the severity of the trauma being treated, but almost all these processes necessitate the measurement of oxygen concentration and air flow rate.
Oxygen concentration and flow rate measurement plays a crucial role in a range of treatment instruments and medical devices, with substantial air flow rates and up to 100% oxygen necessitating accurate measurements in many applications.
Cubic has dedicated more than 18 years’ of its research and development efforts to meeting the stringent gas sensing (quantity and quality) needs of medical and healthcare applications.
Cubic offers comprehensive solutions for oxygen and flow sensing, EtCO2 sensing, CO and CH4 sensing and lung function measurement. The company’s instruments leverage the power of robust technologies, including NDIR, ultrasonic methods, and electrochemical methods.
Ultrasonic oxygen and flow sensors for medical devices
There has been rapidly increasing demand for oxygen concentrators and medical ventilators since 2020 due to COVID-19, placing increased pressure on the healthcare sector. Oxygen and flow sensors for medical devices have therefore become an essential contributor to the work of medical ventilators and concentrators.
Oxygen concentration and flow rate measurement solutions from Cubic are frequently integrated in medical devices. This article provides guidance and best practice on selecting the most appropriate devices for medical healthcare monitoring.
