Intended Use

The CALM system is intended for use as a central monitoring system with signal analysis and display functions and remote repeaters in the perinatal clinical environment. It interfaces with standard fetal and maternal monitors and provides fetal surveillance, monitoring of labor progress, charting, reporting and data analysis, display and archiving functions.

Device Story

CALM (Computer Assisted Labor Monitoring) is a perinatal patient data management system. It interfaces with standard fetal and maternal monitors to acquire Fetal Heart Rate (FHR) and Uterine Activity (UA) signals; it also accepts manual data entry from caregivers. The system processes these inputs to provide real-time monitoring, display, and charting of physiological data for multiple patients simultaneously. It calculates patient age, gestational age, and estimated delivery date. A key feature is the plotting of cervical dilatation over time, which is compared against a reference population. Used in labor and delivery departments by clinicians (doctors/nurses) via networked workstations. Output includes visual displays (chalkboard, tracings), printed reports, and archived data. The system supports clinical decision-making by providing centralized surveillance and labor progress tracking. Benefits include improved data management, standardized reporting, and remote access to patient observations.

Clinical Evidence

No clinical data provided; substantial equivalence is based on technological characteristics and functional comparison to the predicate device.

Technological Characteristics

System consists of personal computers, data acquisition modules, and a system server. Connectivity via network to workstations; remote access via modem. Supports HL7 v2.3 protocol for hospital information system integration. Data sampling rate for FHR is minimum 4 samples per second. Archiving via dual optical disk.

Indications for Use

Indicated for use in the perinatal clinical environment for fetal surveillance and monitoring of labor progress in patients requiring obstetrical care.

Regulatory Classification

Identification

A perinatal monitoring system is a device used to show graphically the relationship between maternal labor and the fetal heart rate by means of combining and coordinating uterine contraction and fetal heart monitors with appropriate displays of the well-being of the fetus during pregnancy, labor, and delivery. This generic type of device may include any of the devices subject to §§ 884.2600, 884.2640, 884.2660, 884.2675, 884.2700, and 884.2720. This generic type of device may include the following accessories: Central monitoring system and remote repeaters, signal analysis and display equipment, patient and equipment supports, and component parts.
