Overview
Brief Summary
The aim of this study is to examine the effect of pelvic floor muscle exercises on the hemodynamic responses of the vena cava inferior in pregnant and non-pregnant women.
Detailed Description
The IVC is responsible for approximately two-thirds of the total venous return to the heart. The blood flow in the IVC is affected by the respiratory and cardiac cycle. One of the factors affecting blood flow is pregnancy. Studies have shown that the hemodynamic responses of the IVC may vary depending on the position, and that the supine position puts pressure on the IVC during pregnancy. Compression of the growing fetus against the IVC can cause supine hypotensive syndrome and fetal danger. However, there is no definite finding about the effects of exercise performed in the supine position. Jefferys et al. reported that the reduction in blood flow at rest is twice that that occurs during exercise and that the level of blood flow should not be a cause for concern in healthy asymptomatic women who choose to exercise in the supine position in late pregnancy. Based on this information, we predict that pelvic floor muscle exercises can change the hemodynamic responses of the IVC and reduce the compression on it. In order to evaluate the effect of pelvic floor muscle exercises on hemodynamic responses of IVC and compression on it, pregnant and non-pregnant women will be measured by ultrasonography. Women eligible for the study will be seated and rested for 30 minutes before taking the measurement. Then, he will be taken to the supine position, rested for 2 minutes, and the first measurements will be taken at the 3rd minute. pelvic floor muscle exercises will be applied for 5 minutes as stated in the literature. Ultrasonographic measurements will be repeated in the supine position immediately after the pelvic floor exercises and 5 minutes after the exercise. Measurements will be applied to all participants in the same order. During the exercises blood pressure, heart rate and peripheral oxygen saturation will be monitored. Before and after the exercises, the heart rate and blood pressure parameters of the women will be recorded.

- •Not having any mental problems that prevent cooperation and understanding.
Exclusion Criteria
- •Pregnant women with acute or chronic diseases with poor placental adaptation and vascular damage such as diabetes, chronic arterial hypertension and preeclampsia, as the fetus is closer to the threshold of hypoxia and acidemia and adaptive phenomena may fail,

Outcomes
Primary Outcomes
Change of Pulsatility index of IVC
Time Frame: immediately after the intervention
Doppler (Toshiba Medical Systems, Aplio 400, Berlin) flow velocimetry will be evaluated.
Changes of IVC diameters
Time Frame: immediately after the intervention
M mode ultrasonography will be used for expiratory (IVC d min) and end-inspiratory (IVC d min) diameter measurement.
Change of the collapsibility index (%) of IVC
Time Frame: immediately after the intervention
The collapsibility index (%) of IVC will be calculated using the formula: \[(Maximum IVC diameter - Minimum IVC diameter)/Maximum IVC diameter\] × 100.
Secondary Outcomes
- Change of Pulsatility index of IVC(5 minutes after the intervention)
- Changes of IVC diameters(5 minutes after the intervention)
- Change of the collapsibility index (%) of IVC(5 minutes after the intervention)
