IntroductionReliable hemodynamic parameters are crucial to prevent perioperative hypotension, one of the most significant modifiable risk factors for postoperative morbidity and mortality. The current standard of care for intraoperative hemodynamic monitoring is achieved through an arterial radial catheter, but its reliability has been increasingly questioned due to the incidence of a phenomenon called the radial-to-central arterial pressure gradient. Studies have shown that this gradient occurs...
