The Pneumatic Tourniquet Technique for Endoscopic Radial Artery Harvest; Does it Affect Patient Hemodynamics?

"Endoscopic radial artery harvesting technique is performed after applying a tourniquet over the distal arm proximally to the elbow. The tourniquet pressure is increased 90 mmHg over the systolic pressure and the tourniquet time will be monitored.~he changes in Heart rate (HR), systolic blood pressure (SBP) and diastolic blood pressure (DBP) will be assessed before and after deflating the tourniquet every 5 minutes for 30 minutes."
