Design and Implementation of a Precision Oxygen Delivery Control System in Facial Masks Oxygen inflammation cases have been constantly recorded, ending up in serious burns for the patients andor even fire breakouts in hospitals. The present work reports the development of a precision oxygen inflammation prevention system, which could be utilized during oxygen therapy. The present approach relies on the utilization of specific contact points on a mask attached to a patientu0027s skin. At the same time, a control system permits or interrupts oxygen flow. Since oxygen flow response times are crucial, capacitive touch sensor technology has been chosen. The final flow control is performed by a properly programed microcontroller. The methodology described in the present work, is expected to have a positive impact in patient management as well as result in savings concerning oxygen reserves in hospital management. Further on, the present apparatus is fully compatible with oxygen masks utilized in a hospital or primary health provider.

Wearable Sensor System to Monitor Physical Activity and the Physiological Effects of Heat Exposure Mobile health monitoring via noninvasive wearable sensors is poised to advance telehealth for older adults and other vulnerable populations. Extreme heat and other environmental conditions raise serious health challenges that warrant monitoring of realtime physiological data as people go about their normal activities. Mobile systems could be beneficial for many communities, including elite athletes, military special forces, and athome geriatric monitoring. While some commercial monitors exist, they are bulky, require reconfiguration, and do not fit seamlessly as a simple wearable device. We designed, prototyped and tested an integrated sensor platform that records heart rate, oxygen saturation, physical activity levels, skin temperature, and galvanic skin response. The device uses a small microcontroller to integrate the measurements and store data directly on the device for up to 48 h. continuously. The device was compared to clinical standards for calibration and performance benchmarking. We found that our system compared favorably with clinical measures, such as fingertip pulse oximetry and infrared thermometry, with high accuracy and correlation. Our novel platform would facilitate an individualized approach to care, particularly those whose access to healthcare facilities is limited. The platform also can be used as a research tool to study physiological responses to a variety of environmental conditions, such as extreme heat, and can be customized to incorporate new sensors to explore other lines of inquiry.
