简要总结
This study focuses on elucidating the changes of hemodynamics assessed by USCOM and respiratory mechanics assessed by impedance oscillometry (IOS) over the course of pregnancy and the postpartum period. Additionally, to understand how these changes over the course of gestation relate to the development of preeclampsia.

结局指标
主要结局
Stroke Volume
时间窗: 1st Trimester at 8-14 weeks, 2nd Trimester at 22-28 weeks, 3rd Trimester at 34-40 weeks, and 4-12 Weeks Postpartum
The volume of blood pumped out of the left ventricle of the heart with each heartbeat.
Cardiac Output
时间窗: 1st Trimester at 8-14 weeks, 2nd Trimester at 22-28 weeks, 3rd Trimester at 34-40 weeks, and 4-12 Weeks Postpartum
The total volume of blood pumped out of the heart and into the rest of the body with each heartbeat.
Systemic Vascular Resistance
时间窗: 1st Trimester at 8-14 weeks, 2nd Trimester at 22-28 weeks, 3rd Trimester at 34-40 weeks, and 4-12 Weeks Postpartum
The level of force (or resistance) against which the heart must work to pump blood into the circulatory system.
Cardiac Index
时间窗: 1st Trimester at 8-14 weeks, 2nd Trimester at 22-28 weeks, 3rd Trimester at 34-40 weeks, and 4-12 Weeks Postpartum
A measure of the pumping capacity of the heart, calculated by dividing one's cardiac output by their body surface area.
R5
时间窗: 1st Trimester at 8-14 weeks, 2nd Trimester at 22-28 weeks, 3rd Trimester at 34-40 weeks, and 4-12 Weeks Postpartum
A respiratory measure of the resistance across all airways, both large and small, using 5Hz soundwaves.
R20
时间窗: 1st Trimester at 8-14 weeks, 2nd Trimester at 22-28 weeks, 3rd Trimester at 34-40 weeks, and 4-12 Weeks Postpartum
A respiratory measure of the resistance across central/large airways only, using 20Hz soundwaves.
X5
时间窗: 1st Trimester at 8-14 weeks, 2nd Trimester at 22-28 weeks, 3rd Trimester at 34-40 weeks, and 4-12 Weeks Postpartum
A respiratory measure of the elasticity of airways using 5Hz soundwaves to calculate the difference in energy to and from lung tissue.
Fres
时间窗: 1st Trimester at 8-14 weeks, 2nd Trimester at 22-28 weeks, 3rd Trimester at 34-40 weeks, and 4-12 Weeks Postpartum
This denotes the Resonant Frequency, which measures the frequency of soundwaves required to balance the internal forces of the lung tissue with its external capacity.
AX
时间窗: 1st Trimester at 8-14 weeks, 2nd Trimester at 22-28 weeks, 3rd Trimester at 34-40 weeks, and 4-12 Weeks Postpartum
Called the Area of Reactance, this is the measure of the area under the curve from the lowest measured frequency to the Resonant Frequency, and reflects the dysfunction of small airways.
R5-R20
时间窗: 1st Trimester at 8-14 weeks, 2nd Trimester at 22-28 weeks, 3rd Trimester at 34-40 weeks, and 4-12 Weeks Postpartum
A measure isolating the resistance of small airways, subtracting the R20 value from the R5 value to calculate the difference. Greater levels of this value correspond to greater small airway resistance.
