Noninvasive ventilation (NIV) can increase survival, alleviate symptoms, reduce hospital admissions, and improve the quality of life of these patients. The key factor in respiratory management of patients with ALS is achieving effective NIV; ineffective NIV has a negative impact on survival, with a reduction of up to 50% compared to patients with an effective technique. The most common cause of ineffective NIV is air leaks; other causes include upper airway obstruction events, residual hypoventilation, hyperventilation, and upper airway obstruction secondary to an oronasal mask. Regular monitoring of the effectiveness of NIV is essential given its impact on survival; the key tools that detect the main problems are the presence of hypoventilation symptoms, arterial blood gases, nocturnal oximetry and capnography, and built-in ventilator software. Different measures have been proposed to address the ineffectiveness of NIV, such as fitting the mask to reduce air leaks, increasing ventilatory support for residual hypoventilation, decreasing ventilatory support for hyperventilation, or a trial with a nasal mask to address oronasal interface effects. In the case of obstruction, the most common measure is to increase positive expiratory pressure during NIV. These measures enable NIV to be effective in 58% of cases, achieving a survival rate similar to that of patients who have effective NIV from the outset.<\/jats:p>","DOI":"10.3390\/jcm14238609","type":"journal-article","created":{"date-parts":[[2025,12,8]],"date-time":"2025-12-08T16:20:29Z","timestamp":1765210829000},"page":"8609","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":4,"title":["Noninvasive Ventilation Effectiveness in Amyotrophic Lateral Sclerosis"],"prefix":"10.3390","volume":"14","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-5778-5983","authenticated-orcid":false,"given":"Jes\u00fas","family":"Sancho","sequence":"first","affiliation":[{"name":"Respiratory Medicine Department, Hospital Clinico Universitario, 46010 Valencia, Spain"},{"name":"Institute of Health Research INCLIVA, 46010 Valencia, Spain"},{"name":"Medicine Department, Medicine Faculty, Universidad de Valencia, 46010 Valencia, Spain"},{"name":"ALS Reference Unit of Comunidad Valenciana, 46010 Valencia, Spain"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-9961-4242","authenticated-orcid":false,"given":"Santos","family":"Ferrer","sequence":"additional","affiliation":[{"name":"Respiratory Medicine Department, Hospital Clinico Universitario, 46010 Valencia, Spain"},{"name":"Institute of Health Research INCLIVA, 46010 Valencia, Spain"},{"name":"Medicine Department, Medicine Faculty, Universidad de Valencia, 46010 Valencia, Spain"},{"name":"ALS Reference Unit of Comunidad Valenciana, 46010 Valencia, Spain"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-8221-6045","authenticated-orcid":false,"given":"Jaime","family":"Signes-Costa","sequence":"additional","affiliation":[{"name":"Respiratory Medicine Department, Hospital Clinico Universitario, 46010 Valencia, Spain"},{"name":"Institute of Health Research INCLIVA, 46010 Valencia, Spain"},{"name":"Medicine Department, Medicine Faculty, Universidad de Valencia, 46010 Valencia, Spain"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2025,12,4]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"480","DOI":"10.1016\/S1474-4422(21)00465-8","article-title":"Recent advances in the diagnosis and prognosis of amyotrophic lateral sclerosis","volume":"21","author":"Goutman","year":"2022","journal-title":"Lancet Neurol."},{"key":"ref_2","doi-asserted-by":"crossref","first-page":"649","DOI":"10.1097\/WCO.0000000000000862","article-title":"Cognitive and behavioural impairment in amyotrophic lateral sclerosis","volume":"33","author":"Pender","year":"2020","journal-title":"Curr.
