Cardio- Exercs And Prescription Flashcards
Can the PT perform Maximal exercise testing ( also known as a Stress test)?
No. Only doctors can.
Ex: treadmill tests w Bruce protocol)
Can the PT perfom Submaximal exercise testing)?
Yes. It’s used as a measure of endurance and exercise capacity.
Ex: 6MWT
How is the 6MWT performed?
- The distance covered by the pt walking at a COMFORTABLE pace for 6 min
-pt is allowed to take breaks as needed
-2 practice trials are required
What ate the parameters for exercise prescription?
FITT
F: frequency
I: intensity
T: time
T: type
The intensity of exercise can be prescribed based on…
- RPE rating of perceived exertion
- percentage of max HR
-percentage of HRR
-percentage of max o2 uptake (Vo2 max)
-Vo2 R reserve
-Mets max
STANDARD intensity ranged based on the following methods: HR max, HRR, Vo2max, Vo2R, METS is…
60-85%
HIGH RISK intensity ranged based on the following methods: HR max, HRR, Vo2max, Vo2R, METS is…
50-75%
How is the percentage of Maximum Heart Rate (HR max) calculated?
Max= 220-age
How is the target HR calculated?
Targer HR= HR max x % intensity desired
How to calculate the Percentage of Heart Rate reserve?
Karvonen equation
Target HR= [( HR max- HR rest) x % intensity desired] + HR rest
What is the canadian physical activity guidelines for exercs?
Adults should accumulate at least 150min of Moderate to vigorous intensity aerobic physical activity per week.
Muscle/bone strengthening activities using major muscle groups at least 2days/week
What is the safety precaution w hypertensive pts?
Upper body exercs may increase SBP.
Avoid high intensive upper body exercs.
What are some indications to terminare exercs session?
-moderately severe or increasing angina
- marked dyspnea
-dizziness,light headedness or ataxia
-cyanosis or pallor
-excessive fatigue
-leg cramps or claudication
- failure of Sbp to rise
-progressively decrease in sbp 10-15mmhg
-hypertensive response
significant chanhes i cardiac rhythm
-blood glucose menor q 60 ou maior d 250
What are some abnorma responses that may be indication to terminate exercs session?
Failure of SBP to rise as exercs continue
Progressive fall in SBP of 10-15mmHG
Hypertensive BP response (SBP more than 200mmHg and or DBP more than 110mmHG
Significant change in cardiac rhythm detected by palpation or ECG
What is the optimal position for V/Q matching when the pt has unilateral lung disease?
Lie on unaffected side “good lung down”
What is the optimal position for V/Q matching when the pt has bilateral lung disease?
Lie in prone
Will improve oxygenation
What is the optimal position for V/Q matching when the pt has pneumonectomy?
Do not lie with affect side up
What is the optimal position for V/Q matching when the pt has ARDS (acute respiratory distress syndrome)?
Lie in prone
What are good positions to decrease dyspnea in COPD pts?
1- standing,leaning back against a wall w hands resting onto thighs
2-standing,leaning against a table
3-sitting,leaning foward w elbows resting on thighs
4-sitting,leaning forward against a table
