1. A portable ventilator system comprising a pneumatic subsystem, a power subsystem, a sensor subsystem and a logic board;
- said logic board further comprising a timing circuit and connected to each of said subsystems;
said pneumatic subsystem, said power subsystem and said logic board further constructed so as to be enclosed within a housing having a recessed control panel;
said pneumatic subsystem further comprising first and second dual head air compressors, said first and second compressor each further comprising two outputs, said compressors constructed so as to compress ambient air;
an accumulator tank connected to each of said two outputs of said first compressor and said two outputs of said second compressor, so as to hold combined outputs of compressed air from each of said compressors;
a connector system, said connector system constructed so as to provide constant, total airflow through said accumulator to a user over a period of time, wherein said logic board is constructed so as to not require microprocessor control; and
wherein said logic board is further constructed so as to control said air that is delivered to said user.
