Non-Invasive Ventilation Sensor Mask (NIVSM): Preliminary Design and Testing

Previous research has emphasized the significance of mask and interface design in non-invasive ventilation (NIV) and the prevention of pressure ulcers (PUs). Multiple variables are involved in the necrosis process, but the skin-mask interface has a significant impact. A preliminary design of a custom-fit Mask (CFM) embedded with a microclimate sensor has been introduced previously. This study aims to improve the comfort and safety of patients who use NIV masks for long periods. The personalized cushion fit (PCF) is designed using 3D scanning and printing technology and integrated into a pre-existing mask. Integration with a preexisting mask has been achieved by fabricating a modular design that acts as a disposable PCF. Embedded sensors are added to the mask to measure the skin-mask microclimate. Real-time data is plotted and monitored for critical conditions and to identify other key features. A preliminary temperature-humidity (T-H) monitoring of the skin-mask interface for both PCF and pre-existing mask shows fluctuation trends that could potentially induce PUs. However, there is a more sensitive reaction in the PCF test. The NIVSM can be combined with a ventilation device and utilized to establish ideal levels of humidity and temperature on the skin to prevent the formation of PUs
