13 In most cases, clinical exercise tests can be supervised by properly trained exercise physiologists, physical therapists, nurses, physician assistants, or medical technicians who are working under the direct supervision of a physician.

Who should not do a treadmill stress test?
Exercise stress testing should not be performed in patients with symptoms of anemia or severe hepatic, renal or metabolic disorders. A resting ECG is an essential part of the pretest evaluation. The patient should have a resting ECG that is free of the abnormalities listed in Table 4.
What is the correct protocol for the Bruce treadmill test?
The modified Bruce protocol has 2 warmup stages, each lasting 3 minutes. The first is at 1.7 mph and a 0% grade, and the second is at 1.7 mph and a 5% grade. This protocol it is most often used in older individuals or those whose exercise capacity is limited by cardiac disease.
How is Bruce protocol performed?
Developed by Robert A. Bruce in 1963 who was an American Cardiologist. 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. Every 3 min the speed & incline of the treadmill are increased.
Can nurse practitioners perform stress tests?
As documented in this expert statement, many groups of non-physicians typically supervise stress tests depending on the needs at various institutions, and these non-physicians include exercise physiologists, physical therapists, registered nurses, nurse practitioners, physician assistants, and other health …
Who runs a cardiac stress test?
Exercise stress test A health care provider monitors the heartbeat while the person walks on a treadmill or pedals a stationary bike. A stress test usually takes about an hour, including both prep time and the time it takes to do the actual test. The actual exercise test takes only around 15 minutes.
When is modified Bruce protocol used?
The Modified Bruce protocol starts at a lower workload than the Standard Bruce, and is typically used for patients who are deconditioned and/or post MI, whose history suggests symptoms at a low workload, and for elderly or sedentary patients who may not be able to keep pace with the faster Standard Bruce protocol.
Is 9 minutes on a treadmill stress test good?
The FAA does accept a minimum of 85% of maximum predicted rate, but stay on the treadmill as long as possible, up to nine minutes to demonstrate maximum effort. “The FAA allows for applicants over age 70 to exercise for at least six minutes, but must still attain 85% of predicted maximum heart rate.”
How high should your heart rate be 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.
What is the difference between the Bruce and modified Bruce protocol?
Conclusions: Modified Bruce protocol has a lighter initial increment, but decreases moderately the capacity of peak exercise due to peripheral fatigue secondary to the first stage of low intensity. Bruce protocol has a higher initial increment but permits to attain higher peak exercise intensities.
Is 12 minutes on treadmill stress test good?
The goal is to have your heart work hard for about eight to 12 minutes to thoroughly monitor its function. You continue exercising until you develop symptoms that do not allow you to continue. Occasionally your doctor may stop the test sooner for other reasons.
How accurate are treadmill stress tests?
Bottom line: In a study where every patient gets the same gold standard, the accuracy of stress test is poor, with sensitivity and specificity both less than 80%.
How long is each stage of Bruce protocol?
In the most widely used test, called the Bruce protocol, there are seven stages, each one lasting for three minutes. If you get to the last stage, you’ll be walking at 5.5 mph up a 20% grade.
How many METs are on the Bruce protocol?
But most importantly: your training status has a massive influence on your maximum METs! Average non-trained women have a maximum METs of around 8 and non-trained men 10. A good maximum METs value for a 30-year-old woman is 14 and for a man 15. Elite athletes can reach maximum METs of up to 22 (women) and 25 (men).
How do doctors perform a stress test?
A stress test is an assessment done in two parts. In a very controlled situation, the heart is stressed using either exercise on a treadmill or a chemical injection, depending on the status of the individual getting the test. Heart rate, rhythm, and blood pressure are continuously monitored throughout the entire exam.
Does a doctor need to be present for a stress test?
The physician must order the diagnostic test and is responsible for training the staff performing the tests, as well as maintaining the testing equipment. He or she does not need to be present in the room during the procedure.

In general, the physician should be present to observe the patient continuously (ie, personally supervise) when the test is performed on a patient with a recent (within 7 to 10 days) history of documented acute coronary syndrome, severe left ventricular dysfunction, severe valvular stenosis (eg, aortic stenosis), or …
Which is better chemical or treadmill stress test?
It may be best to do a chemical stress test as opposed to exercise if you are not able to walk safely on the treadmill, have certain EKG patterns, a pacemaker, or a defibrillator. In addition, if you try the treadmill and cannot achieve the target heart rate, then a chemical stress test will be necessary.
What are the 3 types of stress tests?
There are three main types of stress tests: exercise stress tests, nuclear stress tests, and stress echocardiograms.
How do they do a stress test without a treadmill?
Without exercise In a chemical stress test, the patient receives medications that either speed up the heart rate or dilate the arteries. The body responds in a similar way it would to exercise. A radionuclide is injected into the patient’s arm or hand while resting.
When does Bruce protocol stop?
Stopping the test In clinical practice, patients rarely exercise for the full duration (21 minutes) of the Bruce protocol. However, completion of 9-12 minutes of exercise or reaching 85% of the maximum predicted changes in heart rate is usually satisfactory.
Is the Bruce protocol a maximal test?
Procedure. Bruce test is considered a maximal exercise test where the athlete or client runs to complete fatigue as the treadmill speed and incline are increased every three minutes. Record total running time.
How long does the average person last on the treadmill during a stress test?
The person will exercise for 10–15 minutes but can ask to stop at any time if they feel unwell. If the person experiences any of the following, the doctor might stop the test : dizziness. high blood pressure.
