1. A portable emergency ventilating apparatus, wherein said ventilating apparatus is comprised of:
- 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.

Abstract
A portable emergency respirator is disclosed. This respirator contains an electrical power supply, an air compressor, and a switch which allows one to produce three separate different types of pneumatic outputs from the air compressor. In one mode of operation, the output from the air compressor provides intermittent positive pressure ventilation to the patient. In a second mode of operation, the output from the air compressor is automatically synchronized with the patient breathing. In a third mode of operation, the output from the air compressor is manually controlled by an operator.
