Breathlessness, disability, and exercise tolerance were assessed in 26 patients with severe chronic airflow limitation forced expiratory volume in one second FEV1 less than or equal to 1 litre divided into two groups patients who were normocapnic pressure of arterial carbon dioxide Paco2 less than 5.

The two groups were well matched for spirometric values FEV1 0. All of the hypercapnic patients could improve blood gas tensions towards normal by hyperventilation.

There were no significant differences in visual analogue scores of breathlessness during treadmill exercise, disability oxygen-cost diagram, dyspnoea gradeor exercise tolerance puffwr walk, maximal consumption of oxygen during bicycle ergometry, distance walked to exhaustion in progressive treadmill test.

The findings show that the “fight” to maintain normal blood gas tensions in the face of severe airflow limitation does not have an appreciable cost in terms of disability.
