Abstract: In my previous patent application it was standard medical procedure to give thirty (30) thrusts per minute upon the heart attack victim and then give mouth to mouth resuscitation. A few years ago, Japanese medical scientists recommended one hundred (100) thrusts per minute upon the victim's chest. This is now accepted worldwide in the performing of CPR, thus the CPR standard procedure of thirty (30) thrusts has changed to more than triple its original format.     Because of AIDS, Hepatitis, and more recently, SARS, and other new and in some cases contagious diseases, mouth to mouth resuscitation has been in some cases discouraged. After speaking with cardiologists on this matter it was suggested that oxygen, although not as important as the actual CPR chest thrusts, would certainly do no harm to the patient and, in all likelihood, help the patient. Because of this we have allowed, through our computerized circuit board, a pause after every hundred (30) thrusts and then through the circuit board (or controller), oxygen is allowed into the victim's lungs by way of a line attached to the oxygen bottle. Also proposed is a cell phone connection (911) directly to nearest emergency station or facility so as to allow user immediate response to be built into the apparatus.     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 CPR is the first 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 CPR 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 CPR is a very exhausting challenge most especially if there is only one rescuer available. Depending on the length of time it may take for medical help to arrive, the physical and mental drain on the first aider can be tremendous.   Recent advancement in the CPR 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.   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 CPR life support which, for instance, suggest a downward trust of 5 cm or 2" on the psi of the Electro Pneumatic Control System is preset for an adult victim. Lesser psi is also necessary for smaller framed individuals including children. Hence, a preset weight dial is activated. Allowing the normal sequence of thrusts, such a 1, 2, 3, 4, 5, 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.
