Hypoxia exaggerates inspiratory accessory muscle deoxygenation during hyperpnoea

Abstract The purpose of this study was to elucidate inspiratory accessory muscle deoxygenation and myoelectric activity during isolated volitional hyperpnoea under hypoxic conditions. Subjects performed voluntary isocapnic hyperpnoea (tidal volume = 30–40% of forced vital capacity, breathing frequen...
