Sleep apnea and oxygen saturation in adults at 2640 m above sea level☆
PURPOSE To describe the SpO2 in wakefulness, sleep and during the apnea-hypopnea in adults living in Bogotá, located at 2640 m above sea level. METHODS Descriptive observational study in adults referred for polysomnogram (PSG). A normal Apnea hypopnea index (AHI) was defined as ≤5 and obstructive sleep apnea (OSA) was classified as mild (AHI 5-15), moderate (AHI 15-30), and severe (AHI >30). ...
متن کاملEffect of moderate elevation above sea level on blood oxygen saturation in healthy young adults.
BACKGROUND Arterial hemoglobin oxygen saturation (SaO₂) decreases at an altitude of >1,500 m. There are no reports on normal SaO₂ at altitudes between 0 and 1,500 m. The clinical significance of decreased SaO₂ at such altitudes is unclear. OBJECTIVE To test the hypothesis that in healthy volunteers normal SaO₂ at moderate altitude (MA; 725 m) is lower than that at almost sea level (SL; 43 m)....
متن کاملOxygen saturation, periodic breathing and apnea during sleep in infants 1 to 4 month old living at 2,560 meters above sea level.
UNLABELLED There are few data in the literature related to polysomnography in infants in altitudes from 2,200 m to 2,800 m. The main objective of this investigation was to describe oxygen saturation (SpO2) levels during sleep in infants aged between 1 and 4 months living at an altitude of 2,560 m. The secondary objectives were the description of periodic breathing (PB) and apnea indexes. Polyso...
متن کاملOxygen saturation, periodic breathing, and sleep apnea in infants aged 1-4 months old living at 3200 meters above sea level.
OBJECTIVES To describe, in infants aged 1-4 months old living at 3200 meters above sea level (MASL), oxygen saturation (SpO2), sleep apnea indices, and periodic breathing (PB) during sleep. Polysomnographies were done in 18 healthy infants. RESULTS The median SpO2 was 87%, and the median PB was 7.2% for the total sleep time. The median central sleep apnea index was 30.5/hour, which decreased ...
متن کاملHour-to-hour variability of oxygen saturation in sleep apnea.
STUDY OBJECTIVES Methods used to express the severity of oxygen desaturation during polysomnography include the average oxygen saturation (AO2), lowest oxygen saturation (LO2), and the percent of the total time with oxygen saturation level lower than 90% (T<90%). We wanted to determine which one of these methods is least variable during different hours of monitoring. DESIGN Prospective, obser...
