What causes low ventilator expiratory minute volume?

Low ventilator expiratory minute volume can be caused by several factors, including inadequate tidal volume settings, increased airway resistance, or reduced lung compliance. Additionally, patient factors such as respiratory muscle weakness or obstructive airway conditions can contribute to diminished ventilation. Equipment malfunctions or leaks in the ventilatory circuit may also lead to lower minute volumes. Proper assessment and adjustments are essential to address the underlying causes effectively.
