Abstract
This study assessed the peak expiratory flow rate and pulse pressure during the luteal and menstruation phases of the menstrual cycle. The peak expiratory flow rate and pulse pressure were measured using the Wright’s Peak Flow Meter and Mercury Sphygmomanometer respectively. The peak expiratory flow rate and pulse pressure in the luteal phase were 420.80±12.27 and 42.72±2.52 respectively. While the peak expiratory flow rate and pulse pressure in the menstruation phase were 378.40±11.85 and 35.36±1.95 respectively. The peak expiratory flow rate and the pulse pressure in the luteal phase were significantly higher (p<0.05) than the values during menstruation. The finding may be as a result of the relative increase in progesterone and estrogen levels in the luteal phase. The study thus shows an improved respiratory function and vasodilation during the luteal phase of the menstrual cycle. Keywords: Menstruation, Luteal, Menstrual cycle ,Pulse Presuure, PEFR
Highlights
The physiologic interplay of hormones of the menstrual cycle distinctly divides it into the estrogen dependent proliferative phase and the progesterone dependent secretory phase
A total of 60 volunteers comprising 30 subjects in the late luteal phase of the menstrual cycle and 30 subjects in the menstruation phase of the menstrual cycle participated in the study
A total of sixty subjects volunteered for the study with thirty subjects in the luteal phase of the menstrual cycle and thirty in the menstruation phase
Summary
The physiologic interplay of hormones of the menstrual cycle distinctly divides it into the estrogen dependent proliferative (follicular) phase and the progesterone dependent secretory (luteal) phase. Systemic blood pressure increases relatively at the onset of the menstrual phase when compared to the other phases of the menstrual cycle (Dunne et al, 1991). This study is aimed at comparing the peak expiratory flow rate (PEFR) and the pulse pressure during the luteal and menstrual phases of the menstrual cycle.
