Abstract
Methods and apparatus for the supply of non-invasive positive pressure ventilation by motor-driven blowers, and having fast acceleration between treatment pressures, are described. A blower ( ) supplies treatment pressure of air or breathable gas to a patient mask ( ) via a conduit ( ) at a first pressure and at a second, higher pressure. The blower ( ) receives its power from a power supply ( ) and cascaded motor controller ( ). The power supply ( ) has the capacity to supply sufficient power for the first pressure to be achieved. A static capacitor ( ), that is charged by the power supply ( ), provides the energy to the blower ( ) to achieve the second pressure, during which period the power supply ( ) is effectively shut down.
