Study Summary
The purpose for this research protocol was to examine the role of breathing control mechanisms that determine the development of sleep-disordered breathing in the elderly. This proposal focused on key factors that contribute to the control of ventilation in elderly adults during sleep. The investigators studied the age-specific changes in ventilatory control in older and young adults during NREM sleep.
Primary Outcome
The AT was defined as the end-tidal (PETCO2) that demarcated the central apnea closest to the eupneic PETCO2. The CO2 reserve was defined as the difference in PETCO2 between eupnea and AT.
Interventions
- OTHER 1) hyperventilation via noninvasive positive pressure ventilation 2) multiple trials of episodic hypoxia
