Abstract
Aim: This study evaluated effect of alternate nostril breathing on peak expiratory flow rate (PEFR) in second trimester of pregnancy at the end of 4 weeks. In this study the focus was made on the effect of alternate nostril breathing in improving peak expiratory flow rate.Peak Expiratory Flow Rate (PEFR) is the highest flow that can be achieved during a forced expiration from full inspiration. Peak flow measures the ease with which the lungs are ventilated and reflects resistance in large airways, expiratory muscle strength and effort. Peak expiratory flow rate gets reduced in second trimester of pregnancy due to enlarged gravid uterus, lesser force of contraction of main expiratory muscles like ‘anterior abdominals’ and ‘internal intercostal muscles’, vertical dimension is reduced limiting movement of diaphragm.

Methodology: 60 subjects were selected for the purpose of study from gynaecological hospitals in and around Pune city. Data was collected and peak expiratory flow rate was measured by using Mini wright peak flow meter.
Procedure: 60 females who were in second trimester of pregnancy within the age group of 20-35 years having normal pre-pregnancy BMI were selected and peak expiratory flow rate was measured. The left nostril initiated alternate nostril breathing was performed for 15 minutes in the morning every day of the week for the period of 4 weeks.
Statistical Tool: Paired t-test was used for the pre and post data analysis of the group.
Conclusion: This study concludes that alternate nostril breathing technique is effective in improving peak expiratory flow rate (PEFR) in second trimester of pregnancy with women having normal pre-pregnancy BMI at the end of 4 weeks.
