The early diagnosis of Sleep Disordered Breathing (SDB) may allow proper intervention. Currently, polygraphy (PG) is a reliable and accessible alternative. Objective: To describe and analyze the PG of children >= 1 year old with suspicion of SDB. Patients and Method: PG of children >= 1 year old and adolescents from Concepcion, Chile, with suspected SDB were included, from December 2011 to August 2017. Demographic, clinical and polygraphic variables were collected. It was used descriptive statistics, expressing results in median and range. The association between apnea-hypopnea index (AHI) and oxygen saturation was determined by Spearman's Rho, considering significance of p < 0.05. Results: 190 studies were analyzed. Age 7.9 years old (1.0-20.6), 61% males. Diagnosis: neuromuscular disease (NMD) (24.2%), chronic lung damage (21.1%), upper airway obstruction (UAO) (19.5%), neurological damage (11%), Down syndrome (8.9%), upper airway malformations (7.4%), central hypoventilation (3.7%), obesity (2.6%), and others (1.6%). 55.3% were altered PG, with 53.3% of mild Obstructive Sleep Apnea Hypopnea Syndrome (OSAHS), 30.5% moderate, and 16.2% severe. There were no significant differences in AHI between groups of pathologies (p = 0.032), highlighting a higher AHI in obese patients 9 (0.41-51), and those with NMD 23.9 (0.4-36.6). It was found association between AHI and oxygen saturation parameters: mean saturation (rho = -0.425; p = 0.001), minimum (rho = -0.654; p = 0.001), and oxygen saturation below 90% (rho = 0.323; p = 0.001) in the whole sample. Discussion: There was a high percentage of OSAHS in at-risk pediatric patients, especially in those with NMD and obesity. PG is an accessible and implementable tool in a public hospital, a situation that can potentially be extrapolated to other healthcare centers.
