The CO2, O2, and N2 gradients between alveolar air and arterial blood were measured during a mild steady-state exercise test in three groups of non-smoking men, 20–29, 40–49, and 63–70 years old, respectively. Breathing a low O2-mixture (15.8% O2) the (a-A) D CO2 and the (a-A) D N2 decreased during exercise, compared to room air breathing, when the same exercise level was imposed, indicating a more homogeneous distribution of alveolar ventilation and perfusion under the influence of hypoxia… CONTINUE READING
