Flashcards in Lab 3: Exercising ECGs Deck (13):
List the data we will be interested in for the exercising ECG lab.
List the roles of group members during the exercising ECG lab.
-RPE scale tech
Describe the role of the test administrator before the GXT, during the GXT, and in an emergency.
-Make sure team has all necessary background info
-Choose testing mode, protocol, and pre-determined end point (calculate predicted max HR)
-Explains protocol and obtains informed consent
-Oversees execution of protocol (determines when to progress workload, informs subject when they advance workload, physically changes workload)
-Call for termination of test if end-point is reached or termination criteria are present
-Supervise recovery period
How do we determine the subject's predicted max HR?
85% (220 - age in years)
Describe the role of the ECG tech before the GXT, during the GXT, and in an emergency.
-Obtain resting ECG
-Prep subject for exercising ECG
-Continuously monitor ECG for indications of disease
-Collect 12-lead at end of every stage
-Collect 1 pg rhythm strip at end of every minute
-Label each page w/ subject's name and phase of test
-Continue to monitor ECG and record any changes
Describe the role of the BP tech before the GXT, during the GXT, and in an emergency.
-Measure supine, seated, and pre-exercise (on mode) resting BPs
-Mark location of artery and secure BP cuff in place w/ tape
-Measure BPs at end of every stage
-Stays w/ subject and monitor condition
What does the BP tech need to do in order to accurately measure exercising BP? Why?
Fully support the weight of the arm to minimize muscle tension
When using a treadmill, what does the BP tech need to do in order to accurately measure BP? Why?
Move up and down in time w/ the subject to further reduce muscle tension
When using a bike, what does the BP tech need to do in order to accurately measure exercising BP?
Remove subject's hand from handlebar so noise from the bike doesn't transfer to the stethoscope
Describe the role of the RPE tech before the GXT, during the GXT, and in an emergency.
-Explain how scale works
-Monitor subject for changes in appearance of responsiveness that indicate poor exercise tolerance
-Note responses and stage and time that they occur
-At end of each minute, record subject's RPE and any pain they are experiencing
-Go get first aid and AED kits
-Assist BP tech w/ CPR
Describe the role of the subject before the GXT, during the GXT, and in an emergency.
-Inform testing team of their health and fitness history
-Understand risks and benefits of participation in GXT
-Perform test to the best of their abilities
-Communicate any probs or symptoms
-Remain calm and communicate
How does the RPE scale work?
Subject rates their perception of the level of intensity of the exercise using either a 6-10 Borg scale or a modified 1-10 scale
