  • an electrical power supply;

    an air compressor including conduit means for conveying air compressed by said air compressor to a patient;

    first means for producing a first pulsed electrical signal including a first control means for modifying said first pulsed electrical signal, and wherein said first means is comprised of a timing circuit;

    second means for producing a second pulsed electrical signal including a second control means for modifying said second pulsed electrical signal, and wherein said second means is further comprised of means for sensing a vacuum for producing said second pulsed electrical signal after said vacuum has been sensed;

    third means for producing a third pulsed electrical signal, wherein said third means is further comprised of a first switching means, and wherein said first switching means is comprised of a manually activated switch;

    a second switching means including means for connecting said second switching means to said air compressor;

    said second switching means including means for selectively supplying power to said first means, said second means, and said third means;

    whereby said first means causes said air compressor to provide intermittent positive pressure ventilation to a patient, said second means causes said air compressor to provide compressed breathable gas to a patient in response to said means for sensing a vacuum, and said third means causes said compressor to provide compressed breathable gas to a patient upon manual activation of said first switching means.
