Amyotrophic lateral sclerosis (ALS), as a consequence of the progressive failure of respiratory muscles, often causes chronic ventilatory failure (CVF), indicated by hypercapnia. This study analyses the physiological parameters of breathing in patients with ALS over time and the variables which influence survival time. ⋯ Hypercapnia has a significant impact on the prognosis for ALS patients. In the case of CVF (hypercapnia), the survival time of ALS patients is significantly reduced. NIV is able to significantly increase the survival time of ALS patients with hypercapnia.
