Inclusion criteria
Inclusion criteria: Participants are adult surgical patients who meet all of the following criteria: - Patients aged 19 to 70 years who undergo elective surgery under general anesthesia and are classified as American Society of Anesthesiologists (ASA) physical status I or II - Patients who are planned to be admitted to the general ward, not the intensive care unit, after surgery - Patients who have received a full explanation of the study objectives and procedures and have provided voluntary written informed consent - Patients who are considered to be hemodynamically stable after surgery and suitable for noninvasive blood pressure monitoring (e.g., stable blood pressure in the post-anesthesia care unit without excessive hypertension or hypotension prior to transfer to the general ward) - Patients with no significant problems at the device attachment site (finger) and who are able to tolerate continuous monitoring for up to 48 hours (e.g., capable of independent activity in the ward)
Exclusion criteria
Exclusion criteria: Patients meeting any of the following criteria will be excluded from the study: - Patients who are admitted to the intensive care unit (ICU) after surgery, making ward-based observation infeasible (e.g., transfer to the ICU due to postoperative instability) - Patients who require continuous invasive arterial blood pressure monitoring for blood pressure management, as continuous hemodynamic surveillance is already in place and the study intervention would not be applicable - Patients for whom noninvasive blood pressure measurement is contraindicated in both upper extremities (e.g., risk of lymphedema following lymph node dissection) - Patients with severe arrhythmias or other conditions that result in repeated measurement failure with automated noninvasive blood pressure devices - Patients who are not fully conscious, lack the capacity to provide informed consent, or are otherwise unable to adequately understand or cooperate with study procedures (e.g., severe cognitive impairment) - Pregnant women, as pregnancy is not included in the target population of this study - Any other patients who, in the judgment of the investigator, may be at increased risk or for whom participation in the study may negatively affect patient safety or standard clinical care (e.g., severe pain or conditions that make sustained cuff pressure intolerable)
