Hour-to-hour variability of oxygen saturation in sleep apnea. With altitude, the saturation values differ, however, the majority of the studies has been performed at more than m.

We used averages and standard deviations for the quantitative variables and the proportions for qualitative variables. Obstructive sleep apnea OSA is a frequent condition [1], characterized by recurrent respiratory pauses which lead to sleep fragmentation and intermittent desaturation. Some studies have described the behavior of oxygen saturation during sleep. Acta Med Colomb ;9 1: Daytime pulmonary hypertension in patients with obstructive sleep apnea. Reviewed in May 8 A condition in which the blood is too acidic.

Changes in sleep brecga of athletes under normobaric hypoxia equivalent to m altitude: In this study, we have described the average oxygen saturation.


In six normal subjects, the average SaO2 during sleep were of Valores normales de los gases arteriales y la brecha anionica a nivel de Bogota. Metabolic acidosis, normal anion gap NAG C The clinical impact of sleep disorders at this point may be greater than at sea level and should be studied.

Sleep Science – Sleep apnea and oxygen saturation in adults at m above sea level

This study has some limitations: In Bogota mthe studies of normal values of PaO 2 have been conducted during wakefulness and involves normal and young subjects []. Descriptive observational study in adults referred for polysomnogram PSG.

Additionally, we have not analyzed separately the population with diagnostic of hypoventilation, obesity, obstructive pulmonary disease, nor cardiovascular comorbities. In the group of sleep apnea, Patients who received oxygen during the study, the studies for CPAP titration, and those with less than 4 h, were excluded.

Sleep apnea, High altitude, Oxygen saturation 1. The worst desaturation during REM sleep in patients with sleep apnea has anionifa described and has been related with the duration of apneas during this sleep stage [15].


The value of oxygen saturation and the pulse frequency were determined by an average of a 2 s sample. The effect of altitude descent on obstructive sleep apnea. All desaturation indexes measured on aniomica study were lower in central apnea when compared with OSA [23].

However, at this altitude, PaO 2 is 60 mmHg, from which the curve of hemoglobin dissociation inclines and small changes of PaO 2 have significant repercussions on SpO 2. Content is updated monthly with systematic literature reviews and conferences.

The objective of this study was to describe the oxygen saturation during wakefulness sleep and apneas-hypopneas in adults at an altitude of m.
