Inclusion criteria
Inclusion criteria: ? Pregnant women aged 20 years or older ? Parturients diagnosed with preeclampsia or eclampsia (or preeclampsia superimposed on chronic hypertension) ? Patients who are scheduled to undergo cesarean delivery under combined spinal–epidural anesthesia ?Patients who have received sufficient explanation regarding the purpose and methods of the study and have provided written informed consent for study participation and the use of medical records/physiologic signal data
Exclusion criteria
Exclusion criteria: ? Refusal to provide written consent for study participation and the use of personal information/medical records, or withdrawal of consent at any time ? Cases requiring emergency cesarean delivery due to obstetric emergencies (e.g., severe abnormal fetal heart rate patterns, massive bleeding) ? Cases in which accurate measurement by noninvasive blood pressure devices or finger cuff–based noninvasive blood pressure devices is considered difficult due to severe arrhythmias (e.g., atrial fibrillation), implanted pacemaker, severe structural heart disease, or severe aortic stenosis ? Cases in which invasive arterial catheter insertion or application of a finger cuff device is considered technically difficult or hazardous due to the presence of an arteriovenous fistula in the upper limb (for hemodialysis), severe vascular injury from prior surgery or trauma, or severe peripheral vascular disease ? Cases in which the likelihood of failed noninvasive blood pressure measurement (upper-arm cuff–based or finger cuff–based) is considered high due to severe obesity (BMI = 40 kg/m²) ? Cases in which the study explanation and consent process cannot be appropriately conducted due to decreased level of consciousness, inability to cooperate, or cognitive impairment ? Any other cases in which the responsible investigator or attending anesthesiologist determines that study participation is inappropriate considering the patient’s overall condition, comorbidities, and surgical/anesthetic plan
