WebTraditionally, ventilatory reserve has been evaluated by examining how closely the peak minute ventilation on a CPET approaches the greatest volume of gas that can be breathed per minute by voluntary effort, termed the maximal voluntary ventilation (MVV). Previous guidelines state that breathing reserve [] should be >15% at peak exercise . This ... Webinvasive CPET can provide important clues as to whether the heart or lungs is the severe contributor to symptoms. For example, patients that develop arterial desaturation, or display reduced breathing reserve likely have more severe lung disease, because these are not typical in isolated HF. Alternative exercise methods include echocardiography
