There are numerous methods to find the maximum heart rate. After those initial stages, the modified Bruce protocol METs follows the normal Bruce protocol from stage 1. But higher scores above 0 are associated with more risk for future disease, particularly scores above 1 (which is higher than 84.1% of US adults) or 2 (which is higher than 97.7% of US adults). 2.Treadmill Speed? What is a metabolic equivalent of task (MET)? A MET minute is equal to one minute spent at a MET score of one (inactivity). Evidence from studies done before publication of the guidelines suggested that general anesthesia and epidural anesthesia did not differ significantly in their rates of perioperative cardiac complications.16,17[Reference 16Evidence level A, randomized controlled trial (RCT). A reinfarction rate of 27 to 37 percent occurred in patients who underwent surgery within three months of infarction. Perioperative management of the elderly patient is increasingly important as the elderly population continues to grow. Weight (lbs. These values are based on a person weighing 70 kg, or 154 lbs.
