Abstract

Rapidly responding gas.analyzers have simplified the monitoring of oxygen uptake {Mathematical expression} in the clinical exercise laboratory. An incremental, exhaustive, upright exercise test can be safely used to determine the, plateau in oxygen uptake during exercise, or maximal {Mathematical expression}, in patients with chronic cardiac or circulatory failure. We define {Mathematical expression} in these patients as an increase in {Mathematical expression} of less than 1 ml/min/kg despite an increment in work load. The value for {Mathematical expression} indicates the patient's aerobic capacity; it also predicts the maximal cardiac output during exercise and therefore serves as an estimate of cardiac reserve and of the severity of cardiac or circulatory failure. Symptom-limited {Mathematical expression} during exercise, termed maximum oxygen uptake but more appropriately peak {Mathematical expression}, bears no relationship to {Mathematical expression}. The two terms should not be used interchangeably.
