Mediflo DUO is a dual-use incentive spirometer that can be used for both sustained maximal inspiration (SMI) and positive expiratory pressure (PEP) simply by turning the product round and re-attaching the corrugated tubing. During SMI the flow regulation lid allows the unit to be adjusted according to the patient’s functional capacity, giving a sense of achievement and increased compliance. Low output values for flow and breathing effort (200ml/sec).
During PEP, slow exhalation against resistance of approx 15-20cm H2O increases intrapulmonary pressure, expands the bronchial system, encourages the transport of secretions by means of bronchial calibre fluctuations and assists treatment of pulmonary emphysema. Clear indication of correct pressure. Flow regulation via metering lid.
