ABSTRACT In patients with COPD, an acute worsening of respiratory symptoms is often described as an exacerbation. Exacerbations are associated with a significant increase in mortality, hospitalization, and health-care utilization, but there is currently no widely accepted definition of what constitutes an exacerbation of COPD. This paper summarizes the discussions of the workshop, "COPD: Working Towards a Greater Understanding," in which the participants proposed the following working definition of an exacerbation of COPD: a sustained worsening of the patient's condition, from the stable state and beyond normal day-to-day variations, that is acute in onset and necessitates a change in regular medication in a patient with underlying COPD.

    ABSTRACT: The role of noninvasive positive pressure ventilation (NPPV) has been well established in the treatment of acute hypercapnic respiratory failure due to chronic obstructive pulmonary disease (COPD), however, its benefits in clinically stable hypercapnic COPD patients still not well known, so this trial aimed to assess the efficacy of NPPV in patients with stable hypercapnic COPD.

    ABSTRACT: Mechanical ventilation (MV) weaning trial can be compared to a cardiac stress test where spontaneous ventilation is a form of an exercise and therefore hemodynamic compromise can occur during the weaning process in critically ill patients. The combined increase in arterial pressure and heart rate during unsuccessful weaning is quite suggestive of weaning failure of cardiac origin. Assessment and prediction of weaning failure from cardiac origin remain complicated in patients with chronic obstructive pulmonary disease (COPD). Recent data showed that COPD itself is a powerful independent risk factor for cardiovascular morbidity and mortality, suggesting that occult cardiac dysfunction could be frequent in patients with COPD. The immediate transition from positive pressure mechanical ventilation to spontaneous ventilation may generate significant cardiopulmonary alterations that are complex and mainly include the inspiratory fall in intrathoracic pressure, the increase in work of breathing, and the catecholamine discharge that occur during abrupt transfer from mechanical ventilation to spontaneous breathing. Therefore, it could be suggested that a treatment targeting the cardiovascular system decreasing the preload might help the heart to tolerate the critical period of weaning more effectively.

    ABSTRACT: Patients with COPD are frequently hospitalized for acute exacerbations (AECOPD), which may cause respiratory failure and death. Proportional assist ventilation (PAV) is a relatively new mode of ventilator-based, inspiratory support designed to assist spontaneous breathing in patients with intact neural drive. It is a form of synchronized partial ventilatory assistance with peculiar characteristic that ventilator generates pressure in proportion to patient’s instantaneous effort. Pressure support ventilation (PSV) is an attractive weaning mode, however at higher pressure support levels, many patients displayed expiratory muscle activation indicating that the patient is “fighting the ventilator”.
