The monitor uses electrodes attached to the abdomen and measures the minute electrical signals of the uterine contractions
and fetal heart beats.
Ach and PGF2[alpha] produce uterine contraction
by activation of the muscarinic (M3)-receptor and the prostaglandin FP receptor on the myometrium, respectively (Myatt and Lye 2004; Pappano 2007).
Furthermore, the magnitude, acceleration, and direction of the vector of the stretch force is the product of the sum of the traction force generated by the obstetrician and the propulsive force generated by spontaneous or induced uterine contractions
2: The inhibitory effects on uterine contractions
showed a dose-response relationship.
Stimulation of pregnant rat uterine contraction
by the polychlorinated biphenyl (PCB) mixture Aroclor 1242 may be mediated by arachidonic acid release through activation of phospholipase A2 enzymes.
Effect of different amounts of PGE on uterine contractions
induced by KCl (60 mM), oxytocin (10 mU/ml), Kcl+propranolol, Kcl+naloxane, and barium (4 mM) Uterine contraction
(Mean [+ or -] SD)/PGE extract * Ecbolic agents Type of extract 0.
Timely and effective uterine contraction
is a critical component of parturition (22).
2) Normal uterine contractions
or umbilical cord compressions are the common stressors.
We also recommended new terminology and nomenclature for the description of uterine contractions
University of Geneva, Geneva, Switzerland, et al, concluded that pretreatment with lidocaine vaginal gel reduces intrauterine pressure, uterine contraction
frequency and pain of induced dysmenorrhea, suggesting a new treatment option.
The monitoring system also automatically senses when the mother is having a uterine contraction
and holds blood pressure readings until the contraction is over.

Designed from the ground up at the West Health Institute (watch video), the Sense4Baby system is an innovative, proprietary, portable wireless maternal/fetal monitor and uterine contraction
monitor device that uses custom sensors, software and hardware connected to a cellular network to address high risk pregnancies.
