Patients undergoing major surgery are at risk of postoperative complications. Complications may be preceded by abnormal vital signs. Standard monitoring at general wards is intermittent and manual, leaving the patients unobserved for extended periods.~The chance to enhance monitoring has arisen with recent technological advances in the form of small wearable and wireless devices that continuously record vital signs. Wearable devices enable continuous monitoring outside the intensive care unit and post-anesthesia care unit, thus enabling early detection of patient deterioration. However, before implementing such devices in hospital settings, good accuracy, and precision of measurements is required.~This validation study, which is part of the WARD-SX project, aimed to assess the agreement between vital signs recorded by standard and novel wireless devices
