The reasons for these differences are unknown and difficult to tease apart in clinical populations. If OSA could be temporarily induced in healthy men and women, the causes of some of these differences could be investigated. Nasal blocking has been used to induce OSA in healthy men but its effect in women has not been reported.Patients and Methods: A total of 14 healthy individuals (10 women) underwent in-laboratory diagnostic sleep studies on two occasions separated by a week. On one occasion, the nasal passages were blocked, whereas on the other occasion, participants slept naturally. In both conditions, a full-face mask was used to monitor respiratory events. Participants’ self-reported sleepiness, mood and performance on a motor learning task were assessed in the evening and morning of both sleep studies. Furthermore, endothelial function and self-reported sleep quality were assessed in the morning following each study.Results: Nasal blockage induced OSA in healthy young (age=22± 3 years) and slim (BMI=22.2± 3.2 kg/m2) women (control AHI=2.0± 2.6, blocked AHI=33.1± 36.7 events/hr, p=0.02). One night of OSA was associated with poorer self-reported sleep quality (p< 0.001) and increased self-reported snoring (p< 0.04), choking and gasping during sleep (p< 0.001) but was not associated with alterations in mood, neurocognitive or endothelial function on the following morning.Conclusion: Nasal blockage induces OSA in healthy, young, and normal weight women. However, whether the induced OSA is representative of naturally occurring OSA and the technique useful for future studies is unclear.Keywords: pathophysiology, upper airway collapse, sex, breathing route, obstructive sleep apnea, nasal blockage, femalePittaway IIshkova ABean HMcCarthy SLay IAvraam JDawson AThornton TNicholas CLTrinder JO'Donoghue FJJackson MLJordan ASDove Medical Pressarticlepathophysiologyupper airway collapsesexbreathing routeobstructive sleep apneanasal blockagefemalePsychiatryRC435-571Neurophysiology and neuropsychologyQP351-495ENNature and Science of Sleep, Vol Volume 12, Pp 347-355 (2020) |
