Customized Masks in Non-Invasive Mechanical Ventilation

In non-invasive mechanical ventilation (NIMV), the interface is the primary determinant of success, as adherence and the quality of therapy depend mainly on it. A deteriorated or inadequate mask can lead to unintentional leaks or jaw and tongue displacements, thereby increasing obstructive events in the upper airway. There is a growing interest in the use of personalized masks designed using facial scanning and 3D printing technology. Previous studies have demonstrated their effectiveness in complex patients, such as premature neonates, and healthy individuals, successfully reducing leaks and skin sores. The aim of the project is to demonstrate the utility of a 3D-printed, customised mask to improve the quality of ventilation, primarily by reducing leaks and mask-related obstructions in adult patients receiving home NIMV. Two usage periods of NIMV will be studied, one month with a personalized mask created through 3D printing (M3D) and another month with a commercial mask (MC). The primary variable under study will be the difference in leak levels between M3D and MC throughout the study month with each of them. Variables derived from respiratory polygraphy, performed with each mask, will also be included, in addition to the patient's experience.
