High hazard @ slight & lively depth: what/who is wanted
scientific exam, workout take a look at & MD supervision prior to workout
moderate hazard @ vigorous depth: what/who is needed
best medical examination prior to exercise
low risk @ moderate & full of life intensity: what/who is needed
nothing
mild danger @ slight intensity: what/who is wanted
not anything
which sufferers (threat stratified) may be supervised with the aid of non-doctor health care
experts if professionals are specially educated in CET & medical doctor is with ease/at once
available?
All threat companies may be; low threat may be supervised w/o doctor immediately available
who ought to have PFT's carried out?
All people who smoke <45y.O & anyone presenting with dyspnea
ECG monitoring during test
recorded last 15secs of each stage
BP monitoring during test
measured/recorded last 45secs of each stage
HR monitoring during test
recorded last 5secs of each stage
ECG monitoring after test
monitored continuously, recorded immediately post exercise, during last 15secs of 1st
minute then every 2 minutes thereafter
, BP monitoring after test
measured & recorded immediately post exercise then every 2 minutes thereafter
HR monitoring after test
monitored continuously then recorded during last 5secs of each minute
technetium (tc) -99m
comparison of rest & stress imaging permits ID of fixed & reversible perfusion abnormalities
as well as differentiation; permits higher does with less radiation exposure; preferred imaging
agent
thallum 201
circulates myocardium showing images of where lack/inadequate blood flow is; shows
images of inadequate perfusion
dobutamine
elicits wall motion abnormalities by increasing HR & therefore myocardial O2 demand;
infused intravenously with dose increased gradually until maximal does or endpoint is
acheived
adenosine (dipyridamole)
causes maximal coronary vasodilation in normal epicardial arteries; rest images then
compared with imaging obtain after coronary vasodilation
optimal ExRx
cardiorespiratory fitness (CRF), muscular strength, muscular endurance, flexibility, body
comp, & neuromotor fitness (gradual progression of volume/intensity)
overload principle
states exercise below minimum intensity will not challenge body sufficiently to result in
changes in physiologic parameters
intensity (light, moderate, vigorous(
light = 30-40%
moderate = 40-60%
vigorous = 60-90%
HRR method
