Objectives: To analyze the prevalence of nocturnal hypoventilation (NHV) in hypercapnic COPD patients and to determine predictive...

...Yoshitaka Oku; Gerald M. Saidel; Neil S. Cherniack; Murray D. Altose Remarkable augmentation of breathing discomfort has been noted when ventilation is constrained to the steady state level during progressive hypercapnia. However, the effect of willful enhancement of ventilation on breathing...

... is a disorder associated with recurrent arousals and chronic activation of the sympathetic nervous system, leading to daytime sleepiness and disturbances in the autonomic system. Hypoventilation results from reduced alveolar ventilation and is associated with hypercapnia. In rare cases it is caused by genuine...
