Arterial Waveform Analysis for Predicting Post-induction Hypotension
Noninvasive and Continuous Arterial Waveform Analysis for Predicting Post-induction Hypotension of Endoscopic Surgery Patients.
The goal of this observational study is to develop a computation model for accurately predicting post-induction hypotension in patients receiving laparoscopic surgery under general anesthesia. The main question[s] it aims to answer are:
• whether the corresponding characteristics on pressure wave forms could be use to predict post-induction hypotension.
Participants will be observed before and after induction of general anesthesia for non-invasive arterial pressure wave forms and blood pressure changes.
