Prospective, observational study of the changes in hemodynamic variables such as blood pressure, cardiac output, systemic vascular resistance, and of changes in respiratory variables such as vital capacity, and functional residual volume.A cohort study of 100 healthy pregnant women tested with non-invasive methods during pregnancy and 6 months after delivery.
Primary Outcome Measures:
- Pregnancy specific changes in hemodynamic variables [ Time Frame: Normal pregnancy time frame ] [ Designated as safety issue: No ]
Secondary Outcome Measures:
- Respiratory functional changes [ Time Frame: Normal pregnancy time frame ] [ Designated as safety issue: No ]

Healthy pregnant women with the willingness to consent in physiologic tests at 3 different time points during, and one time point after pregnancy. Spirometric tests will be performed with V-MAX, non-invasive measuring of hemodynamics will be measured by Finometer.
