Abstract :
Alternating breath test (ABT) evaluated peripheral chemoreceptor function. The ventilatory response to ABT is measured in infant by mean alternation coefficients. The authors´ simulations and measurements show the test can lead to unreliable values if the absolute value of minute ventilation is drifting during the test. The large errors the authors found suggest that ventilation should be de-trended before calculations
