ARAYA - GOMEZ, Vivien  y  ALPIZAR - RIVAS, Rodolfo. Use of Ambulatory Holter monitoring with oxygen saturation in evaluation of patients with suspect of sleep apnea. Rev. costarric. cardiol [online]. 2014, vol.16, n.1, pp.05-12. ISSN 1409-4142.

Justification and Objective: the respiratory abnormalities that may occur during the sleep period are frequent. Sleep apnea has an important place as a health problem, because of the association with arrhythmias, metabolic abnormalities, hypertension and ischemic hearth. To diagnosis this condition is not easy because of the complexity and cost of the methods, like the polisomnography. The objective of this paper is to present the experience with the Ambulatory Holter Monitoring with 24 hours Oxygen Saturation (OxyholtherR), as an initial diagnosis method for this condition. Methodology: descriptive study of the main findings in the OxiholtherR in the ¨Centro Cardiológico Integral¨ between the year of 2005 and 2013. The study analyzed the presence of oxygen saturation abnormalities during the night period according to the age, gender, and weight. This abnormalities were classify base on the severity and the time in which the desaturation lasted. Results: we analyzed 494 studies, the age in general average was 65 years, 279 (56 %) were mans and 215 (43 %) women. A 10 % (51 cases) had a normal oxygen saturation level. Of the 443 (90 %) studies that show a significant decrease in saturation, 43 % had this decrement for a period of time less than 30 minutes and 57 % extended for more than 30 minutes until 10 hours. In 33 % of the group with abnormalities show mild decrease in saturation levels (saturation 80 to 88 %), 39% had moderate decrease (saturation 70-79 %) and 28 % show saturation level below 69 % (severe). In the 443 cases with nocturnal low oxygen saturation, 88 patients (20 %) had arrhythmias in the same nocturnal period. Conclusions: sleep apnea is a frequently health problem in adult patients. There are mild and other very severe cases of sleep apnea. The OxyholtherR of 24 h is a simple, not invasive and useful method to begin the evaluation of patients in which there is suspicion of sleep apnea.
