Babcock, and M. Effect of gender on the development of hypocapnic apnea/hypopnea during NREM sleep. J Appl Physiol 89:, We hypothesized that a decreased susceptibility to the development of hypocapnic central apnea during non-rapid eye movement (NREM) sleep in women compared with men could be an explanation for the gender difference in the sleep apnea/hypopnea syndrome. Suffolk UniversityWe studied eight men (age yr) and eight women in the midluteal phase of the menstrual cycle (age yr); we repeated studies in six women during the midfollicular phase. Hypocapnia was induced via nasal mechanical ventilation for 3 min, with respiratory frequency matched to eupneic frequency. Tidal volume (VT) was increased between 110 and 200% of eupneic control. Cessation of mechanical ventilation resulted in hypocapnic central apnea or hypopnea, depending on the magnitude of hypocapnia. Nadir minute ventilation in the recovery period was plotted against the change in end-tidal PCO 2 (PET CO2 ) per trial; minute ventilation was given a value of 0 during central apnea.
