摘要：
A portable ventilator uses a Roots-type blower as a compressor to reduce boththe size and power consumption of the ventilator. Various functional aspectsof the ventilator are delegated to multiple subassemblies having dedicatedcontrollers and software that interact with a ventilator processor to provideuser interface functions, exhalation control and flow control servos, andmonitoring of patient status. The ventilator overcomes noise problems throughthe use of noise reducing pressure compensating orifices on the Roots blowerhousing and multiple baffling chambers. The ventilator is configured with ahighly portable form factor, and may be used as a stand-alone device or as adocked device having a docking cradle with enhanced interface and monitoringcapabilities.
