Plusmed Pm-Fm4 Full Face Mask Medium

Plusmed PM-FM4 Full Face Mask The PM-FM4 Full Face Mask non-invasively directs airflow to a patient from a positive airway pressure device, such as a continuous positive airway pressure (CPAP) or Bi-level BiPAP system. For use by adult patients (>66 lb / 30 kg) for whom positive airway pressure therapy is prescribed. Intended for single-patient reuse in the home environment and multi-patient reuse in the hospital/institutional environment. General Features: Light Flexible Silent Adjustable headband Dimensions: Small-Medium-Large Technical Specifications: Dead Space Information: The dead space of the mask varies depending on the buffer size, but is less than 260 ml. Treatment Pressure: 4 to 30 cmH²O Resistance: Measured pressure drop (average values ​​for 3 sizes) 0.15cmH²O at 50lt/min, 0.5cmH²O at 100lt/min Inspiratory and Expiratory Resistance: Inspiratory resistance of the mask (when used with the Non-Rebreathing Valve) 1.8 cmH²O at 50 lt/min Mask expiratory resistance (when used with Non-Rebreathing Valve) 2.0 cmH²O at 50 lt/min Anti Asphyxia Valve open atmospheric pressure: < 4cmH²O Anti Asphyxia Valve closed atmospheric pressure: < 4cmH²O Noisy : Declared binary noise emission values ​​in accordance with ISO 4871.
