<P>PROBLEM TO BE SOLVED: To provide an apparatus for automatic delivery of chest compressions and ventilation to a patient. <P>SOLUTION: The apparatus includes: a chest compressing device configured to deliver compression phases during which pressure is applied to compress the chest and decompression phases during which approximately zero pressure is applied to the chest; a ventilator configured to deliver positive, negative, or approximately zero pressure to the airway; and a control circuitry and processor. The control circuitry and processor are configured to cause the chest compressing device to repeatedly deliver a set containing a plurality of systolic flow cycles, each systolic flow cycle comprising a systolic decompression phase and a systolic compression phase, and at least one diastolic flow cycle interspersed between sets of systolic flow cycles, each diastolic flow cycle comprising a diastolic decompression phase and a diastolic compression phase, wherein the diastolic decompression phase is substantially longer than the systolic decompression phase. <P>COPYRIGHT: (C)2012,JPO&INPIT |
