Finite Element Method
In late years, the patient load of chronic respiratory failure disease, such as a Obstructive Pulmonary Disease (COPD) or Sleep Apnea Syndrome (SAS) increaseschronic obstructive pulmonary disease (COPD) and sleep apnea syndrome (SAS), is increasing. For the patient, in whom such condition is comparatively serious, non-invasive positive pressure ventilation (NPPV) may be prescribed. Since this disposal method uses a nasal mask, a patient is treated non-invasively. Although, It is reported that skin obstacles arise, such as a pressure necrosis and compression gangrene, by the reason the mask pressed the face. Consequentially, it was created that the finite element model of the face portion based on a human body slice picture, and the stress which acts on the contact area of a nasal mask was calculated. And, It turned out that a nasal mask suitable for the form of an individual face is required, in order to reduce a skin obstacle.
