Sustained hyperoxia stabilizes breathing in healthy individuals during NREM sleep.
The present study was designed to determine whether hyperoxia would lower the hypocapnic apneic threshold (AT) during non-rapid eye movement (NREM) sleep. Nasal noninvasive mechanical ventilation was used to induce hypocapnia and subsequent central apnea in healthy subjects during stable NREM sleep. Mechanical ventilation trials were conducted under normoxic (room air) and hyperoxic conditions ...
متن کاملArterial blood pressure response to transient arousals from NREM sleep in nonapneic snorers with sleep fragmentation.
STUDY OBJECTIVES To assess the hemodynamic effects of graded arousals during nonrapid eye movement (NREM) sleep in patients with partial upper airway obstruction during sleep without obstructive sleep apnea/hypopnea, overnight beat-to-beat BP was recorded in six patients. SETTING At the end of each nonapneic obstructive event, EEG responses were graded as follows: grade 2, grade 1, and grade ...
متن کاملNasal continuous positive airway pressure for nonapneic snoring?
The feasibility of nasal continuous positive airway pressure (CPAP) for heavy snoring associated with daytime sleepiness was studied in 118 consecutive patients with an apnea hypopnea index below 5. Fifty-nine of them reported daytime sleepiness in a questionnaire and were offered treatment with nasal CPAP. Whereas 48 patients refused it, the remaining 11 (19%) accepted nasal CPAP for home ther...
متن کاملPosthypoxic ventilatory decline during NREM sleep: influence of sleep apnea.
We wished to determine the severity of posthypoxic ventilatory decline in patients with sleep apnea relative to normal subjects during sleep. We studied 11 men with sleep apnea/hypopnea syndrome and 11 normal men during non-rapid eye movement sleep. We measured EEG, electrooculogram, arterial O(2) saturation, and end-tidal P(CO2). To maintain upper airway patency in patients with sleep apnea, n...
متن کاملSpindle Power Is Not Affected after Spontaneous K-Complexes during Human NREM Sleep
K-complexes and sleep spindles often grouped together characterize the second stage of NREM sleep and interest has been raised on a possible interaction of their underlying mechanisms. The reported inhibition of spindles power for about 15 seconds following evoked K-complexes has implications on their role in arousal. Our objective was to assess this inhibition following spontaneous K-complexes...
