Around 300 million surgical operations are performed globally, and of these, 40 to 50 million are performed in the USA. The perioperative period is characterized by hemodynamic instability and, most importantly, hypotension. Intraoperative hypotension is frequent, and the incidence ranges between 5% and 99% during non-cardiac surgery, depending on the definition. The aim of the study is determined as the relationship between two different time intervals of measurements and time spent hypotensive under harm thresholds in non-cardiac surgery in adults having non-cardiac surgery. Secondarily, it will be determined if more frequent non-invasive blood pressure measurement use decreases postoperative acute kidney injury. Exploratory, it will be evaluated if more frequent non-invasive blood pressure use causes pain or nerve injury in the arms or not.

The time-average spend hypotensive (under MAP thresholds of 65 mmHg) for at least 1 minute
Timeframe: Every 2.5 minute in the surgery upto end of the surgery.
