Peak expiratory flow rate and Pulse Pressure values during the Luteal and Menstruation Phases of the Menstrual Cycle

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
