Transcutaneous CO₂ monitoring as indication for inpatient non‐invasive ventilation initiation in patients with amyotrophic lateral sclerosis

Amyotrophic lateral sclerosis (ALS) is characterized by profound muscle weakness, including diaphragmatic weakness resulting in hypercapnic respiratory failure. While non-invasive ventilation (NIV) is usually initiated in the home, patients presenting with hypercapnic respiratory failure may be at high risk of adverse outcomes with delays in treatment. We aim to describe the clinical utility of transcutaneous CO2 (TCO2 ) to assess the need for...
