Hypercapnic and hypoxic ventilatory responses in parents and siblings of children with congenital central hypoventilation syndrome.
Marcus CL, Livingston FR, Wood SE, Keens TG. Marcus CL, et al. Am Rev Respir Dis. 1991 Jul;144(1):136-40. doi: 10.1164/ajrccm/144.1.136. Am Rev Respir Dis. 1991. PMID: 2064119
Instantaneous minute ventilation, mean inspiratory flow (tidal volume/inspiratory time), and respiratory timing (inspiratory timing/total respiratory cycle timing) were calculated on a breath-by-breath basis. Hypercapnic ventilatory responses were 1.97 +/- 0.32 L/min/mm Hg …

Theophylline does not increase ventilatory responses to hypercapnia or hypoxia.
Swaminathan S, Paton JY, Ward SL, Sargent CW, Keens TG. Swaminathan S, et al. Am Rev Respir Dis. 1992 Dec;146(6):1398-401. doi: 10.1164/ajrccm/146.6.1398. Am Rev Respir Dis. 1992. PMID: 1456555 Clinical Trial.
We measured hypercapnic and hypoxic ventilatory responses using rebreathing techniques in 15 subjects (21 to 41 yr of age, with normal lung function) on three occasions: baseline, after 4 days of Drug 1, and after 4 days of Drug 2. For subjects receiving theophylline, the …
