Quiz 1 - 2 Flashcards

1
Q

dyspnea - 5

A

Shortness breath at rest, with mild exertion or usual activities - anything that makes the heart work harder - cold weather, inclines, large meal
○ Abnormally uncomfortable awareness of breathing
○ Strenuous exertion in healthy trained
○ Mod exertion in healthy untrained
○ Abnormal
§ Occurs at a level of exertion not expected to evoke symptom
□ May indicate heart failure or pulmonary disease

68
Q

eval of ex response - 3

A

○ Determine functional capacity/ex tolerance
○ Symptoms
○ Help guide ex prescription/plan

69
Q

Principles of ex testing - 4

A
  • Protocol should accommodate ind’s ability to perform the ex
    ○ Lower impact/less demanding
  • If using a multi stage protocol, intensity should increase gradually in 2-3 mins stages - metabolism to stabilize and reach a steady state - not solely anaerobic
  • Increments in work rate should be chosen to test time ranges bw 8-12 mins
  • Typically, HR, BP and ratings of perceived exertion are measured and symptoms
    ○ ACSM’s guidelines for ex testing and prescription
70
Q

Gen testing procedures - 9

A
  • Review how pt is feeling - health status change?
  • Verify meds/ that they have taken them
  • Ensure pt is wearing comfortable clothing and appropriate footwear - tell them to prepare before hand - closed toe shoes
  • Familiarize participant with protocol/equipment/consent form
  • Obtain resting vitals - i.e. HR, BP, O2 stat
  • Monitor vitals and RPE as appropriate during test (HR last 10-15 seconds of each stage, BP last 30-60 seconds, Re LAST 10-15 SECONDS - then active recovery - walk to get their HR and BP back to normal - presyncope or syncope if stopped too quickly
    ○ BP in 30 seconds or less
  • PT’s appearance and symptoms should be monitored regularly
  • Cont low level ex until HR and BP stabilize but not necessarily until they reach pre-ex values
    Recheck vitals in recovery for at least 5 mins unless abnormal
71
Q

13 general indications for stopping a test

A
  • Onset of mod=severe angina or angina-like symptoms (>/- 3/5 on standard angina scale) ○ Track numbers to see if there is any change
  • Increase nervous system symptoms - ataxia, dizziniess, or near syncope
  • Signs of poor perfusion - i.e. light-headedness, confusion, pallor, cyanoisis, nausea, or cold and clammy skin)
  • Shortness of breathe, wheezing, leg cramps, claudication
  • Physical or verbal manifestation of severe fatigue
  • Drop in SBP >/- 10mmHg with an increase in work rate, or if SBP decrease below value obtained in same position prior to testing
  • Excessive rise in BP:SBP>250mmHg and or DBP >115 mmHg
  • Failure of HR to increase with increase in ex intensity
  • O2sat - 80, normal >/- 95%
  • HR > age predicted max (i.e. 220-age) - accurate within 10 beats - closer - closer to being done the test - good to use 85% of max
  • Failure of the testing equipment
  • Participant requests to stop
    Participant has completed the protocol
72

92
Q

How to estimate VO2max with submax tests

A

HR/time

93
Q

limitation of submax tests

A

○ Requires assumptions in order to estimate VO2 max - breaking those would affect your results

94
Q

6 assumptions to estimate VO2 max

A
  1. A linear - straight line - relationship exists bw HR, VO2 and workload (i.e. HR 110-150bpm)
    1) Stroke volume plateaus in this range
  2. Diff bw actual and predicted max HR is minimal
    1) i.e. predicted Hrmax = 220-age, accuracy +/- 10bpm
  3. A steady - state HR is obtained at each work rate in 3-4 min
    1) HR in last two min of stage - 5bpm
  4. Mechanical efficiency is the same for everyone at a given workload
  5. Participant is not on any meds that alter HR response (i.e. beta-blocker)
  6. Participant is not on high quantities of caffeine, ill or in a high temp environment - all may alter HR response to ex
