PeriCALM Patterns is intended for use to provide additional secondary information as an adjunct to qualified clinical decision-making during antepartum or intrapartum obstetrical monitoring at ≥32 weeks gestation for annotation and summary of the fetal heart rate recording for baseline, accelerations and the uterine pressure recording for contractions. WARNING: Evaluation of FHR during labor and patient management decisions should not be based solely on PeriCALM Patterns annotations or summaries and should include inspection of the fetal monitor tracing and consideration of all pertinent clinical information.

PeriCALM Patterns 3.0 is a software device to be used with fetal/maternal monitoring systems. The subject device is a software algorithm to detect, label and measure features (accelerations, decelerations, baseline, and contractions) in electronic fetal monitoring (EFM) records. PeriCALM Patterns 3.0 uses fetal monitor data imported through an interface with an external source or with a third-party clinical information system. PeriCALM Patterns can function in a networked environment or as a standalone workstation. The subject device includes present-day Long and Short-Term Memory (LSTM) neural networks to identify segments of a fetal heart rate tracing corresponding to accelerations, decelerations, baseline as well as uninterpretable segments where is missing tracing. Contraction detection is achieved using the same processes as the predicate device.
