the pha measured during this phase was duplicated during the later continuous infusion of nahco3 at which time either 1 ) ventilation was held constant at the control level , allowing arterial carbon dioxide tension ( paco2 ) to rise as a consequence of the bicarbonate dissociation , or 2 ) paco2 was held constant by servo control of ventilation .
