WebThe range of values for “breathing reserve” was broad ( Fig 4 ), and seven of our normal subjects in fact had a “breathing reserve” of less than 11 L/min at the end of exercise. The second method assesses the ratio of V ˙ e max/ V ˙ co 2 max. A mean value of 31.9±4.4 for male subjects has been reported. 7. WebEvidence-based recommendations on the clinical use of cardiopulmonary exercise testing (CPET) in lung and heart disease are presented, with reference to the assessment of exercise intolerance, prognostic assessment and the evaluation of therapeutic interventions ( e.g. drugs, supplemental oxygen, exercise training).
