Internal Jugular Vein Collapsibility Index as a Predictor of Hypotension

Internal Jugular Vein Collapsibility Index as a Predictor of Hypotension After The Induction of General Anesthesia in Geriatric Patients Undergoing Laparoscopic Colorectal Surgeries: A Prospective Observational Study

The internal jugular vein (IJV) collapsibility index has been proposed as a practical alternative of of the inferior vena cava collapsibility index (IVC-CI), as it is easily accessible using bedside ultrasonography. Several studies have demonstrated a correlation between IJV collapsibility and central venous pressure as well as right atrial pressure.
