1. (8pts) From these data, graph your mean arterial pressure (MAP; see formula) and heart rate (y axes) vs. workload (in METS) on the x-axis (include resting results). Using this information, answer the following questions. Show ALL work.
MAP = [1/3 (SBP-DBP)] +DBP
MAP: [1/3 (SBP-DBP)] + DBP Resting (supine) - [1/3 (118-72)] + 72= 87.33~87 mmHg Resting (standing) - [1/3 (108-70)] + 70= 82.67~83 mmHg Bruce Protocol Stage 1 - [1/3 (120-64)] + 64= 82.67~83 mmHg Bruce Protocol Stage 2 - [1/3 (130-68)] + 68= 88.67~89 mmHg
METs: Resting = 1 MET Bruce Protocol Stage 1= 4.6 METs Bruce Protocol Stage 2 = 7 METs
Heart Rate: Resting (supine) - 64 bts/min Resting (standing)- 127 bts/min Bruce Protocol Stage 1- 126 bts/min …show more content…
The narrowing of the artery walls is going to make moving oxygen through them much harder than it would be in healthy arteries. So if a patient with atherosclerotic arteries performed the same test, they would show a higher double product. The patient 's resting double product is going to start higher and, with exercise, the patient will most likely become fatigued more quickly.
4. (3 pts) What is the risk for a cardiac related event during exercise (or exercise testing)? Please provide statistical examples (i.e. 1 event for every X number of individuals). Also, elaborate on various populations (i.e. young, adult, male/female, etc.). (Hint; guidelines Ch. 1)
The risk for a cardiac related event occurring during exercise for a healthy individual is very low when participating in moderate exercise. The rick increases when an individual is exercising at a higher intensity. Data has shown that one per 133,000 men and one per 769,000 women athletes of high school and college age are at risk for an exercise related death. Cardiac related deaths among young individuals was one per 185,000 men and one per 1.5 million women. A sudden cardiac death is one per 15,000-18,000 for adults who showed previous signs. Overall, six cardiac events were shown for every 10,000 tests, showing the risk is low for a cardiac related event to occur during exercise or exercise …show more content…
Acute infection with fever, lymph gland inflammation or general body aches.
Relative Contraindications:
1. High degree atrioventricular block.
2. Elevated resting blood pressure; > 200 systolic or >110 diastolic.
3. Neuromotor, musculoskeletal, or rheumatoid disorders that are exacerbated by exercise.
The difference between absolute and relative contraindications deal with the decision to continue exercise or to stop exercise. When you have an absolute contraindication, you want to discontinue exercise immediately because continuing with exercise can be harmful to the patient. With a relative contraindication, you will want to monitor the patient very closely to make sure the exercise testing does not become dangerous for the patient to continue.
6. (3 pts) what is RPE and why do we use it? (Please provide a short paragraph on the importance of RPE) RPE stands for Rate of Perceived Exertion and is used to determine how the patient is feeling during each stage of the protocol. The RPE correlates to the intensity of the exercise and how hard the patient feels their body is working. It is a tool to be able to self-monitor during the exercise so the physician who is running the test knows where the patient is and how much more they can
