Cardiopulmonary Part Seven Flashcards
what is rate pressure product
the product of systolic BP and HR
average exercise frequency, intensities, and METs
3-5 sessions/week
moderate intensities/duration
> 5 METs
what is rating of perceived exertion (RPE)
subjective rating of feelings during exercise and impending fatigue
when should systolic BP rise
increasing workloads and VO2
when are resistive exercises usually prescribed
later rehab after a period of aerobic conditioning
for Phase I inpatient cardiac rehab, when is return to indepencence and ADLs initiated
24 hours (or until theyre stable for 24 hours)
what is transtelephonic EKG monitoring
used to monitor patients as they exercise at home
when does HR plateau in exercise
before maximal oxygen uptake
for exercise, what are absolute indications
drop in systolic over 10 mmHG with increased workload
moderate/severe angina
increasing nervous system symptoms (ataxia, dizziness, near syncope)
signs of poor perfusion
technical difficulties in monitoring EKG
subject’s desire to stop
sustained VT
ST elevation over 1.0mm
how many METs for daily/multiple daily sessions for low intensity
under 5 METs
what is ambulatory monitoring (telemetry)
continuous 24-hour EKG monitoring
the category-ratio scale interpretation
scored 1-10
0 = nothing at all
5 = strong
10 = extremely strong
how is VO2 max with arm ergonometry compared to leg ergometry
lower VO2 max with arm ergometry
at discharge of Phase I cardiac inpatient rehab, what METs should be used
over or equal to 5 METs
early rehabilitation for exercise prescription: activity should be…
discontinous (interval training) with frequent rest periods
how does HR increase linearly
a function of increasing workload and oxygen uptake
____ % of HR max corresponds to __% of functional capacity or VO2 max
70-85% HR max
corresponds to
60-80% functional capacity or VO2 max
intensity used for resistive exercise prescription
moderate: 60-80% of 1 rep
exercise prescription for post-PTCA (percutaneous transluminal coronary angioplasty)
wait to exercise vigorously 2 weeks post-PTCA (to allow inflammatory process to subside)
walking program initiated immediately
severely compromised individuals may benefit from… (regarding conditioning)
multiple, short exercise sessions spaced throughout the day
3-10 minute sessions
who is RPE especially used for
people who don’t exhibit the typical rise in HR (patients on medications that depress HR (beta-blockers))
what is a MET equal to
3.5 mL/kg per minute
for moderate intensity exercise, what is average conditioning time
20-30 minutes
increased myocardial oxygen consumption (MVO2) indicates
increased coronary blood flow
what happens to EKG in exercise in healthy person
reduced R wave
increased Q wave
EKG changes with exercise for someone with CAD
significant tachycardia (occurs at lower level of exercise)
exertional arrhythmias (increased frequencies)
ST segment depression (horizontal or downsloping depression greater than 1 mm)
RPE is measured between…
6-20
max HR AND METs post-MI for Phase 1 Inpatient Cardiac Rehab
for how long
70% max HR/5 METs
6 weeks post-MI
with increasing workloads, what should happen to diastolic BP
should remain the same
is abrupt beginning or cessation of exercise recommended
no
maximal oxygen uptake AKA
VO2 max
an ST segment depression more than 1 mm below baseline indicates
MI
how long should warm up and cool downs be
5-10 minutes
exercise prescription post CABG
limit UE exercise while sternal incision is healing
avoid lifting, pushing, pulling for 4-6 weeks post surg
purpose of the category-ratio scale
rates exercise intensity
are exertional arrhythmias normal during exericse
yes
what does Valsalva do to BP and work of heart
dramatic increase in BP
increased work of heart
what does gradually increasing/decreasing intensity of exercise do to the body
promote circulatory and muscular adjustment to exercise
what does beta blocking affect
ability of HR to rise in response to exercise stress
typical exercise intensity is __%-___% of functional capacity
60-80
minimal METs to promote endurance
5-6 METs
what is a MET
the amount of oxygen consumed at rest
what do pacemakers affect
the ability of HR to rise in response to an exercise stress if it is fixed
how many METs for Phase I Cardiac Inpatient Rehab TO START
2-3 METs
heart rate range or reserve can more closely approximate the relationship between…
HR and VO2 max
cardiovascular effects with arm egometry compared to low ergometry
higher HR
lower SV
higher sytolic and diastolic BP
resistive exercises are contraindicated with
uncontrolled HTN
arrhythmias
for uncomplicated MI, how long is hospital stay
3-5 days
oxygen uptake AKA
VO2
