Moni-Patch Temperature Data Collection for Algorithm Development During Surgery

This is a prospective, single-center study designed to collect synchronized Moni-Patch and esophageal temperature data for algorithm development and refinement. Approximately 30 adult patients undergoing elective surgery under general anesthesia lasting at least 120 minutes will be enrolled. A Moni-Patch sensor will be attached to the skin over the carotid artery in the neck. The sensor will communicate wirelessly with a PC-based data logger to continuously record temperature measurements and device data. Esophageal temperature will be monitored using a clinically indicated temperature probe connected to the patient monitoring system. Synchronized temperature data will be collected during surgery. At least 120 minutes of valid simultaneous Moni-Patch and esophageal temperature measurements will be targeted for each participant. Data collection will also include patient characteristics, surgical and anesthesia information, warming conditions, device-use information, and relevant environmental conditions. The collected data will be used to identify opportunities for algorithm improvement and to characterize device performance internally. Descriptive analyses may be performed, but no formal clinical accuracy hypothesis test or pass/fail acceptance criterion is planned. Moni-Patch readings will not be used to guide clinical care.
