Veterinary Vital Sign Time-Series Database during General Anesthesia (PhysioNet, 226 canine/feline cases)

This resource contains physiological time-series recordings from dogs and cats undergoing inhalational general anesthesia at VIP Animal Medical Center, Cheongdam, Seoul, Republic of Korea. The dataset was assembled from routine clinical recordings obtained in 2026 and includes 226 anesthesia cases (191 canine and 35 feline). Some cases were stored as multiple sequential recording files, and a small number of animals contributed more than one case; animal-level identifiers are not included in this release. Data were acquired using Vital Recorder from Dräger Infinity M540 patient monitors and, where connected to the recording system, Dräger Atlan A350 anesthesia workstations. Available signals differ between recordings: some contain monitor-derived numerical measurements only, whereas others additionally contain physiological waveforms and/or anesthesia-machine measurements and settings. Accompanying clinical metadata describe species, breed, age, sex, neuter status, body weight, physical status, and procedures performed. The release includes 241 de-identified recording files, totaling approximately 369 hours of recording, together with file-level signal inventories, a data dictionary, and an example for reading the recordings. The resource supports exploratory veterinary perioperative physiology research, signal-processing method development, and feasibility assessment for future larger studies. It represents a single-center, availability-based cohort rather than a complete census of anesthetized patients; heterogeneous signal availability and limited subgroup sizes should be considered when interpreting analyses.
