Description of intervention(s) / exposure
Observations of cardiac function using transthoracic echocardiography at the time of treatment interventions. Transthoracic echocardiography will be performed prior to and after treatment interventions and also after the intervention of passive leg raising to assess stroke volume changes. Transthoracic echocardiography will also be performed in healthy pregnant women at rest and during passive leg raising. Transthoracic echocardiography examination will take approximately 15 minutes. The post-intervention measurements will occur within 60 minutes of the drug being administered.
