Arterial pressure is monitored and obtained
Arterial pressure
After the induction of anesthesia, 20G catheter is placed for invasive arterial pressure monitoring in the radial artery and pressure sensor is attached for noninvasive arterial pressure monitoring in the contralateral radial artery. Then, invasive and noninvasive arterial pressures are monitored and obtained simultaneously.
Time frame: For 30 min after the induction of anesthesia,
