Cardiopulmonary resuscitation (C.P.R.) is a technique employed to ventilate the lungs as well as to oxygenate and circulate blood through the body when the heart and lungs cease to function effectively. When a patient stops breathing respiratory gases can be exchanged by means of a rescuer blowing air directly into the mouth or airway and thence to the lungs. When the pumping action of the heart fails, blood can be circulated by the rhythmic alternation of compression and relaxation on the lower half of the central chest, or sternum. Basic C.P.R. is the fast step in a sequence of support measures designed to sustain life by supporting vital organ functions that are transiently failing or arrested. Some of the disadvantages of the manual performance of C.P.R. are the methods employed by rescuers. If too much pressure is applied to the victim a rib or ribs can be broken. This in turn may force the broken rib to puncture the lungs thereby doing irreparable damage. Once the lung deflates due to such a puncture the victim now in heart failure, also has to contend with an added serious problem. Also as any rescuer will attest, performing manual C.P.R. is a very exhausting challenge most especially if there is only one rescuer available. -2- Depending on the length of time it may take for medical help to arrive the physical and mental drain on the first cider can be tremendous. Recent advancement in the C.P.R. area has helped rescuers to keep victims alive, however, it is fully dependent on the skills and professionalism of the people involved. Hence, "The Portable C.P.R. Life Enhancement System". This apparatus is so designed as to allow its mechanical functions to provide adequate compressions on the victim's chest while simultaneously allowing oxygen into the victim's lungs. The Portable C.P.R. Life Enhancement System is an apparatus which is so designed as to perform two separate features in a simultaneous fashion. Consisting of a strong wide belt that is placed under the victim's back and is then secured by a specially designed belt buckle. A pneumatic pump is built in to the open ended belt and is, when fastened unto the victim, adjusted for P.S.I. requirements dependent on the size of the victim. As well two mini canisters of oxygen, being part of the assembly are used along with an oxygen hose and mask which is placed over the victim's mouth. Using the recommended compressions for medical C.P.R. life support which for instance suggest a downward thrust of 5 cm. or 2" on the P. S.I. of the Electro Pneumatic Control System is preset for an adult victim. Lessor P. S.I. is also -3- necessary for smaller framed individuals including children. Hence, a preset weight dial is activated. Allowing the normal sequence of thrusts such as 1001 - 1002 - 1003 - 100 - 1005, etc. the oxygen cylinders at precisely timed intervals allow a deep breath through the face mask. Once the sequence is maintained the system is continued until the victim is placed on board the emergency vehicle and can be so used until reaching the nearest hospital. This automatic lifesaving system further allows rescue personnel to work on other external injuries such as excessive bleeding, broken or fractured bones and any additional trauma sustained by the victim. Even in the event of placing a victim unto a backboard and being pulled by ropes up over a cliff or difficult terrain, the Portable C.P.R. Life Enhancement System will continue to perform while the victim is basically in mid air. A rechargeable battery pack allows the full unit to work continuously for hours at a time.
