In addition, EMG data will be obtained via the electrodes. This will be analyzed real-time and compared with the toco and/or IUPC contraction information. When the toco signal fails (e.g., when the patient moves and the strap no longer overlies the uterus), the patient's nurse will be asked to reposition the strap. We may count the frequency with which nursing intervention is required. This intervention is always required when a patient is monitored with a toco, we are merely counting the frequency of required nursing intervention.
