Recall now that Type 2 respiratory failure defined by hypoxia AND hypercapnoea is due to ventilatory failure, treat the oxygenation by providing increased MAP.In addition, treat hypercapnoea by increasing the minute ventilation (MV) by increasing the tidal volume. (MV = Respiratory rate multiplied by Tidal Volume).Tidal volume can be manipulated by providing a further increase of pressure at beginning of inspiration, this is called inspiratory positive airway pressure (IPAP). It lasts only during inspiration.At expiration, the airway pressure drops to an elevated (compared to patients intrinsic) PEEP called expiratory positive airway pressure (EPAP).
