Response of Pulmonary Functions to Deep Breathing Exercise in Twin Pregnancy

Study Overview
=================
Brief Summary
-----------------
this study is to investigate the response of pulmonary function to deep breathing exercise in twin pregnancy

Detailed Description
-----------------
Physiological changes during pregnancy impose numerous changes on the respiratory system that can affect the health of both mother and foetus. Regarding the importance of the normal breathing in the health of mother and foetus. Many investigators have studied pulmonary function tests during normal pregnancy, most of them found a significant decrease in pulmonary function test parameters during all pregnancy trimesters. Others showed that the PFTs parameters are normal in the first trimester but there was significant decrease in them in the second and third trimesters, or in the third trimester only. Study Design: Randomized control trial Sixty twin pregnant women during the third trimester i (27th weeks gestation),aged 25 to 35 years old and body mass index was ≥ 30 kg/m², will participate in this study. They will be assigned into two equal groups; control group and study group ( study group only will make deep breathing exercise inform of diaphragmatic and costal breathing 3times a day for 15 repetitions each exercise for 9 weeks, pulmonary function test will be applied for both groups at 27th week gestation and at 36th weeks gestation.

What is the study measuring?
-----------------
Primary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| forced vital capacity (FVC) | inspiratory reserve volume + tidal volume+ expiratory reserve volume | FVC will be applied at 27th week gestation and at 36th weeks gestation (3 months) | 
| Forced Expiratory Volume in 1 Sec (FEV1) | Pulmonary Function Tests: (Forced Expiratory Volume in 1 Sec) | FEV1 will be applied at 27th week gestation and at 36th weeks gestation (3 months) | 
| FEV1/FVC | ratio between Forced Expiratory Volume in 1 Sec (FEV1) and forced vital capacity (FVC) | FEV1/FVC will be applied at 27th week gestation and at 36th weeks gestation (3 months) |
