Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

1. Ultrasound records at least one quiet breathing cycle and one deep inhalation cycle to calculate IJVV
2. Propofol was infused target-controlled at 4 μg/ml, and changes in arterial blood pressure within 3 minutes of propofol induction were observed.
3. Aim to conduct a prospective observational study to evaluate the correlation between internal jugular vein variability during deep inhalation and the decrease in blood pressure during propofol induction.
