What is the standard Bruce protocol?
In the standard Bruce protocol, the starting point (ie, stage 1) is 1.7 mph at a 10% grade (5 METs). Stage 2 is 2.5 mph at a 12% grade (7 METs). Stage 3 is 3.4 mph at a 14% grade (9 METs). This protocol includes 3-minute periods to allow achievement of a steady state before workload is increased.
How many stages are in Bruce protocol?
According to the original Bruce protocol, the patient walks on an uphill treadmill in a graded exercise test with electrodes on the chest to monitor the EKG. Every 3 minutes, the speed and incline of the treadmill are increased. There are 7 such stages and only very fit athletes can complete all 7 stages.
How high does your heart rate go during a stress test?
Your target heart rate during a stress test depends on your age. For adults, the maximum predicted heart rate is 220 minus your age. So, if you’re 40 years old, the maximum predicted heart rate is 220 – 40 = 180.
How long is each stage of Bruce protocol?
The Bruce protocol is a standard test in cardiology and is comprised of multiple exercise stages of three minutes each. At each stage, the gradient and speed of the treadmill are elevated to increase work output, called METS.
How long do you walk on a treadmill for a stress test?
You will be asked to walk on a treadmill for approximately 5 to 15 minutes. The test begins slowly and increases gradually in speed and incline every two to three minutes. During this time, your heart rate, blood pressure and EKG will be monitored.
Is 13 METs good on a stress test?
Exercise capacity is based on metabolic equivalents (MET) achieved, (one MET is defined as 3.5 mL O2 uptake/kg per min, which is the resting oxygen uptake in a sitting position). Less than 5 METS is poor, 5–8 METS is fair, 9–11 METS is good, and 12 METS or more is excellent.
How do I increase my METs score?
One MET minute equals one minute spent at a MET score of 1 (inactivity). To reach 1,000 MET minutes, a person could combine brisk walking and low-impact aerobics, both with a MET score of 5, for 200 minutes a week (5 x 200 = 1,000). Generally, an improvement in health requires 500-1000 MET minutes a week.
What is the standard Bruce Protocol?
Level 1 – 10% Incline at 2.7 km/h
What are the stages of Bruce Protocol?
– By convention, the maximum predicted heart rate is calculated as 220 (210 for women) minus the patient’s age – A satisfactory heart rate response is achieved on reaching 85% of the maximum predicted heart rate – Attainment of maximum heart rate is a good prognostic sign
What is the Bruce Protocol?
Never presume customers have the mental capacity to make the decision in question.
How many Mets are on the Bruce Protocol?
In the standard Bruce protocol, the starting point (ie, stage 1) is 1.7 mph at a 10% grade (5 METs). Stage 2 is 2.5 mph at a 12% grade (7 METs). Stage 3 is 3.4 mph at a 14% grade (9 METs). This protocol includes 3-minute periods to allow achievement of a steady state before workload is increased.
