Experimental: Custom Mask Interface
Patients use a custom mask interface for one month with an option to use for a year if it performs better than a commercial mask.
Device: Custom Mask Interface
Subjects enrolled in the study will received a custom designed, 3D printed, non-invasive ventilation mask interface.
- Average number of hours the custom NIV mask interface is used per night [ Time Frame: 1 month ]Average number of hours the custom NIV mask interface is used per night
- Leak parameters from device [ Time Frame: 1 month ]Average minutes in large leak or leak measured from the device in liters per minute and averaged over the month
- Tidal volume measurements [ Time Frame: 1 month ](average measured tidal volume/average set tidal volume)*100%
- Interviews with subjects regarding their experience with the custom mask Qualitative assessment of custom NIV mask efficacy [ Time Frame: 1 month ]Interviews with subjects regarding their experience with the custom mask
- ALS Depression Inventory-12 (ADI-12) [ Time Frame: 1 month ]Depression Scale. Scales: For each question, the following is selected: "I fully agree", "I agree", "I don't agree", "I do not agree at all"
- ALS Functional Rating Scale, Revised (ALSFRS-R) [ Time Frame: 1 month ]Functional Rating Scale. Scales: Customized for each question, but 4 is the maximum and generally means 'normal', and 0 represents significant impairment.
- ALS Specific Quality of Life-20 (ALSSQOL20) [ Time Frame: 1 month ]Quality of Life Scale. Scales: For each question, 1-10 is selected, where 10 means "extremely" and 0 means "not at all".
- Epworth Sleepiness Scale (ESS) [ Time Frame: 1 month ]Sleepiness Scale. Scales: 3 means "high chance of dozing", 2 means "moderate chance of dozing", 1 means "slight chance of dozing", and 0 means "would never doze".
- PROMIS Neuro-Quality of Life Fatigue Scale [ Time Frame: 1 month ]Fatigue Scale. Scales: For each question, "Always" (5), "Often" (4), "Sometimes" (3), "Rarely" (2), and "Never" (1) is selected.
- PROMIS Neuro-Quality of Life Sleep Disturbance Scale [ Time Frame: 1 month ]Sleep Disturbance Scale. Scales: For each question, "Always" (5), "Often" (4), "Sometimes" (3), "Rarely" (2), and "Never" (1) is selected.
