The first generation sensor suite of the Sensatex System can also accommodate fetal and maternal vital signs monitoring. Pregnant women with chronic medical problems, past history of preterm delivery, or abnormalities of the fetus or placenta are at increased risk of complications. Of chronic conditions, high blood pressure, diabetes, anemia, excess or shortage of amniotic fluid, and lung disease in the mother are the most commonly reported causes of pregnancy complications. Expectant mothers with these conditions accounted for nearly 11% of, or 429,000, pregnancies in 1998. The Sensatex System currently has the ability to measure fetal heart rate, uterine contractions, maternal body temperature, and fetal movement. Later generations of the System will also monitor urine albumin, blood glucose, and fetal pressure.
