Abstract

Pulsioximetry has been validated as a very reliable non-invasive technique to assess arterial saturation (SaO2). Our aim was to study the variations of SaO2 during aerobic exercise in different groups of women: pre- and post-menopausal. Arterial desaturation was classified as light, moderate, and serious. Thirty-one sedentary women gave their consent to participate voluntarily in this study and were divided into two groups: pre-and post-menopausal. We measured SaO2 during a 60-minute session of aerobic dance, every 15 minutes, to determine the level of each participant�s arterial desaturation. At rest, no significant differences in SaO2 between groups were observed. However, the pre-menopausal group had a higher frequency of normal SaO2 (92.3%) than post-menopausal women (66.7%). Light arterial desaturation was less frequent in pre (7.7%) than post-menopausal (27.8%) women. Moderate levels of desaturation were only observed in post-menopausal women (5.6%). In conclusion, post-menopausal women experience more arterial desaturation than pre-menopausal women during aerobic exercise. Pulsioximetry and arterial desaturation evaluation may be a useful tool for post-menopausal women, who suffer more desaturation, in order to detect high intensities when other means are not available, both due to its relationship with lactate production as well as being a very simple and non-invasive technique.
