Custom Fit Non-Invasive Ventilation Mask with Microclimate Monitor: Preliminary Study

Mask and interface design have been emphasized in previous research in relation to Non-invasive Ventilation (NIV) and pressure ulcer prevention. A number of variables contribute to necrosis, but critical research has shown that the skin-mask interface is the most important. The goal of this study is to determine whether preexisting ventilation mask designs can be modified in order to improve clinical outcomes. A Custom-Fit ventilation Mask (CFM) was created using 3D scanning and printer technology. A disposable, custom-fit cushion has been fabricated in order to integrate with a pre-existing mask. A mask is equipped with embedded sensors that measure the microclimate between the skin and the mask as precisely as possible. 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 shows fluctuation trends that could potentially induce PUs. However, there is a less sensitive reaction in the original mask test.
