Subjects be identified during their clinical course in the ED and will be randomized to either the LifeFlow® fluid delivery or an IV fluid bolus through the Alaris® pump (standard of care). IV fluids will be provided until the subject notes the sensation of a full bladder, at which point, the standard of care clinical practice is to perform the ultrasound. The transabdominal pelvic ultrasound requires a full bladder for optimal visualization of the ovaries, adnexa, and uterus, and is the only alternative to a transvaginal pelvic ultrasound for virginal young women. All other clinical care is per standard of care. The only research component is the randomization and data collection.
