    Poor Conditioning
    Present with [blank_start]increased[blank_end] HR and low/mod workloads with normal ECG and Vt, RR, Ve <[blank_start]70[blank_end]% MMV


    Poor Effort
    Present when ECG, SaO2 and HR are [blank_start]normal[blank_end] and anaerobic threshold is [blank_start]not[blank_end] achieved and Ve <[blank_start]70[blank_end]% MMV

  7. 7Workload: Amount of [blank_start]energy[blank_end] being generated by patient during exercise. Measure in kilopond meters (kpm)

    Power: Amount of [blank_start]work[blank_end] per minute. Measure in [blank_start]watts[blank_end]. 1 watt = 6.12 kpm/min


    Metabolic Equivalents (METS) – Unit that measures O2 [blank_start]consumption[blank_end] per kg of body weight. 1 met = 3.5 mL/O2/kg (normal at rest) VO2 is measured during test and [blank_start]divided[blank_end] by pt weight in kg, then divided by 3.5 to get METS.

    Anaerobic Threshold – Level of exercise or VO2 at which [blank_start]anaerobic[blank_end] metabolism will begin to supplement aerobic metabolism. Lactic acid increases, pH decreases, HR is stable, Ventilatory equivalent for O2 and CO2 changes.

    O2 Max – [blank_start]Work[blank_end] continues to increase but [blank_start]VO2[blank_end] does not.

  8. 8Steady State Vs Multistage Testing
    Steady State – Pt is exercised at [blank_start]submaximal[blank_end] level for 5-8 minutes at 50-[blank_start]75[blank_end]% of max load.
    (220-age = max HR)
    Once that target is reached, timing begins, measurements are made during final [blank_start]1[blank_end]-[blank_start]2[blank_end] minutes.

    Multistage – Workloads are [blank_start]increased[blank_end] and measurement made at the end of each [blank_start]stage[blank_end] (increase at 15 watts/min)
    <50 watts – [blank_start]low[blank_end]
    50-100 watts – [blank_start]medium[blank_end]
    >100 watts – [blank_start]high[blank_end]
    200 watts [blank_start]too[blank_end] high for stress testing.
    Can be changed every [blank_start]1[blank_end]-[blank_start]6[blank_end] minutes by increasing [blank_start]speed[blank_end], grade, or [blank_start]resistance[blank_end].

    To verify treadmill is at a 10% incline – take a [blank_start]30[blank_end]” carpenter’s level and place on treadmill. The High end should be [blank_start]3[blank_end]” above the low end.
    3” Rise / 30” run = 10
    Set workload at [blank_start]10[blank_end] – [blank_start]15[blank_end] watts/min to reach 100 -150 watts in 10 min.

  9. 9Stress Test without Gas Analysis (Multistage)
    Prepare Patient: 12 lead [blank_start]ECG[blank_end] – resting. Hx and physical exam. Informed consent
    Equipment: Treadmill, cycle or step
    Pt is stressed until [blank_start]Max[blank_end] HR achieved or pt develops [blank_start]symptoms[blank_end] that indicate to stop.
    Workload should gradually be [blank_start]decreased[blank_end] and pt monitored until vitals return to [blank_start]normal[blank_end]


    Stress testing with Gas Analysis (Steady State)
    Pt is prepared and stressed at [blank_start]sub[blank_end] maximal level for 5-8 minutes
    Expired gas is collected near [blank_start]end[blank_end] of each stage and during final [blank_start]1[blank_end] – [blank_start]2[blank_end] minutes of testing
    Collected using: Volume Spirometer, pneumotach, or breath by breath analysis.
    Measurement Includes: Exhaled [blank_start]Volume[blank_end], Temperature, Time of collection, respiratory [blank_start]rate[blank_end], [blank_start]Fe[blank_end]O2, [blank_start]Fe[blank_end]CO2
    Allows for calculation of: [blank_start]Minute[blank_end] ventilation, Vt, [blank_start]VO2[blank_end], CO2 Production, Respiratory Exchange [blank_start]Ratio[blank_end], VE/VO2, VE/VCO2

  10. 10Stress Testing with Gas Analysis and ABG
    ABG is performed [blank_start]same[blank_end] time as gas analysis
    Inability to stabilize arm for [blank_start]puncture[blank_end] is a problem. Arterial line would be [blank_start]preferred[blank_end]
    Indicated for patients with primary [blank_start]pulmonary[blank_end] problems
    Additional measurements: Physiologic [blank_start]Deadspace[blank_end], [blank_start]VA[blank_end], VD/Vt, [blank_start]Cardiac[blank_end] Output
