This research aims to explore new methods for assessing cardiovascular function by evaluating oxygen uptake during exercise.
Analyzed oxygen uptake (VO2) and carbon dioxide output (VCO2) during exercise stimuli.
Utilized the Fick principle to relate blood flow parameters to oxygen transport.
Assessed initial and subsequent changes in VO2 to detect circulatory disturbances.
Estimation of cardiovascular function using VO2 in the first 15 seconds of exercise provides critical insights.
Increased VCO2 in relation to VO2 indicates the anaerobic threshold and subsequent lactic acid production.
Defined dynamic coupling of external and cellular respiration offers direct, noninvasive information about cardiovascular mechanisms.

Karlman Wasserman (1988) studied this question.
