Abstract
The present invention has been developed primarily for a flow diverting valve used in controlling the pressure and flow rate, and measuring the flow rate, of a breathable gas supplied to the airways of a patient by a breathable gas supply apparatus during, for example, nasal Continuous Positive Airway Pressure (CPAP) treatment of Obstructive Sleep Apnea (OSA) and ventilatory assistance treatments such as non-invasive positive pressure ventilation (NIPPV).
