CPET Analysis Review

These flashcards cover key vocabulary and concepts related to cardiopulmonary exercise testing (CPET) as discussed in the lecture.

CRITERIA FOR MAXIMAL TEST

Parameters that must be met for a maximal cardiopulmonary exercise test, such as RER >1.05-1.15, workload >80% predicted, exercise duration of 8-12 min, and heart rate exceeding 80% (some guidelines >90%).

RER

Respiratory Exchange Ratio, a measure of the ratio of carbon dioxide produced to oxygen consumed during exercise.

pVO2

Percent predicted VO2, indicating an individual's oxygen consumption capacity compared to a predicted value.

O2 pulse

The amount of oxygen consumed per heartbeat, calculated by VO2/HR.

AT

Anaerobic Threshold, which represents the exercise intensity at which lactate starts to accumulate in the blood.

VO2/work

The ratio of oxygen consumption to workload, typically expressed in mL/min/W.

SpO2

Peripheral oxygen saturation, the percentage of oxygen-saturated hemoglobin in the blood.

VE/VCO2

The ratio of minute ventilation (VE) to carbon dioxide production (VCO2), used to assess ventilation efficiency.

RPE rating (modified Borg)

A subjective measure of exertion ranging from 0 to 10, where 10 represents maximal effort.

Normal Response in CPET

Expected physiological responses during CPET, such as pVO2 >80% predicted, VO2/work 9-11 mL/min/W, and SpO2 >95% or less than 4% drop.
