Acta Med Colomb 13 suppl. Gasimetria arterial en adultos jovenes sanos en Bogota. Patients who received oxygen during the study, the studies for CPAP titration, and those with less than 4 h, were excluded. N Engl J Med ; Sleep and breathing in recreational climbers at an altitude of and m: Metabolicus acidosisMetabolikus acidosisMetabolikus acidosis k. In six normal subjects, the average SaO2 during sleep were of Apnea duration and hypoxemia during REM sleep in patients with obstructive.

For the definition of hypopnea and consequently, for the diagnosis of OSA, oxygen desaturation is involved as one of its components [2,3]. Sleep Sci ;6 2: Acta Med Colomb ;7 6: All desaturation indexes measured on the study were lower in central apnea when compared with OSA [23]. Gasimetria arterial a diferentes edades en Bogota. 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.

Patients should address specific medical concerns with their physicians. Back Links pages that link to this page.

Sleep apnea and oxygen saturation in adults at 2640 m above sea level

Acid and Base Disorders Chapter. Eur Respir J ;8: Metabolic bdecha, increased anion gap IAG C Acta Med Colomb ;9 1: Although access to this website is aniknica restricted, the information found here is intended for use by medical providers. Some studies have described the behavior of oxygen saturation during sleep. Nephrology – Acid and Base Disorders Brecya.

Started inthis collection now contains interlinked topic pages divided into a tree of 31 specialty books and chapters. Obstructive sleep apnea OSA is a frequent condition [1], characterized by recurrent respiratory pauses which lead to sleep fragmentation and intermittent desaturation.

Due to the fact that patients with more severe AHI were older and had higher BMI, additional future studies are dully required to evaluate the impact of these variables upon SpO 2 at Bogota’s altitude, as well as the possible differences that might exist between genders. The effect of altitude descent on obstructive sleep apnea.

Anionia Bing Images Extra: Respiratory events and periodic breathing in cyclists sleeping at m simulated altitude. The saturation decreased mildly with age, ranging from The impact of this upon the development of complications such as pulmonary hypertension in patients with SAHS at this time, is still undetermined. The worst desaturation during REM sleep in patients with sleep apnea has been described and has been related with the duration of apneas during this sleep stage [15].

Related links to external sites from Bing. Gasimetria arterial y alveolar en adultos sanos a nivel de Bogota. The apnea-hypopnea index AHI was defined as the total number of apneas and hypopneas per hour of sleep.

The strengths of this study were the significant number of patients included and that this is as our best knowledge, the first article describing the behavior of oxygen saturation during sleep in individuals with OSA, living at high altitude above mcontributing for better understanding of this pathology among our population and in populations living in similar altitudes.

Pulmonary hemodynamics in the obstructive sleep apnea syndrome. Accepted em May 14 Additionally, we have not analyzed separately the population with diagnostic of hypoventilation, obesity, obstructive pulmonary disease, nor cardiovascular comorbities.

The clinical impact of sleep disorders at this point may be greater than at sea level and should be studied. Acidosi metabolicaAcidosi metabolica NAS.

The sleep stages were classified according to international criteria during the years of study Reschtchaffen and Kales [13]. The value of brechaa saturation and the pulse frequency were determined by an average of a 2 s sample.

Findings of the majority of studies performed at altitude are not comparable with the ones of our study, since they were performed after acute exposition to altitude, which can induce the appearance of central apneas and reflect the changes that are detected with an early adaptation [22].

The studies during sleep in intermediate altitudes are few and were performed at simulated altitudes normobaric hypoxia [20,21]. Metabolic acidosis, normal anion gap NAG C Desaturation was larger lower SpO 2 during apnea or hypopnea events for all the severity groups of OSA.

To establish the degree of statistical significance of the different proportions, we used the chi square test. Causes include diabetes, kidney failure and shock. Patients with severe OSA had higher desaturation during wakefulness In this study, we have described the average oxygen saturation.
